Other creatures and plants have a much greater effect on what happens. Because of the recent rapid growth, this means that whoever is alive today makes up 6.5 percent of this extremely high number. Which biome is the most stable? If we do or don’t do it, someone will laugh, Your email address will not be published. Deserts cover 33 percent of the land area of the earth. The correct figure for the percentage of the earth’s land mass which is actually occupied by humans is .03%. Area of water: 361 740 000 km2 (139 668 500 square miles), this are 71% of the total surface of the Earth. 40 billion people would also raise the CO2 emission greatly causing inccreased climate change, which is the cause of stronger hurricanes, animal and plant population decrease and poor air quality for everyone, shortening the life span of humans. However, even non-urban areas contain roads, train tracks, farms and other marks of human domination. Rivers constitute the smallest volume of Earth's water--aside from biological water in Earth's occupants--with a volume of 509 cubic miles. There are also other discrepancies within your article, so I’m not sure if you just copy&pasted some of the bits (which would be fine generally) without truly thinking about them. So, like it or not, we humans are insignificant in the real workings of the earth, but we are an egocentric species, who overstate our importance. Forests cover 31 percent of the world’s land surface, just over 4 billion hectares. In The Salt of the Earth (2014 a photographer Sebastiao Salgado suggested that half of the world is inhabited. Tracts of land around the world have been designated as protected areas due to their natural, cultural, or ecological value. Twenty-nine percent of Earth is land, and seventy-one percent is water. Yes you’re right, thanks for pointing this out! Seen from space, the majority of the Earth’s surface is covered by oceans – that makes up 71% of the surface of the Earth, with the remaining 29% … In my research all of the data found on the land surface area was around 1.5 × 10 8 km 2 . I would agree that the percentage of 10% is untouched by humans/uninhabited is extremely low. Interestingly, 108 billion people have ever walked this earth. Top subjects are Literature, Business, and History. So this means that out of 1000 units of land, we occupy three. Doing some writing research and this is usual :O, We should convert sea water into sweat water and we should make canals for providing water in all deserts of the world and that area where rocky barren land where we put arable sand in this way our earth can support 40 billion people. Online tool for visualization and analysis. I say that because this would have to be a consideration in your “conclusion”. The United Nations (UN) has set a goal for 10% of the world's oceans to be protected by 2020. If you continue to use this site we will assume that you are happy with that. Learn how your comment data is processed. Water covers approximately 70 percent of our world's surface. About 1/3. About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. percentage, but how to measure the area. https://www.scienceworldreport.com/articles/12366/2014012... https://www.usgs.gov/special-topic/water-science-school/s... What human activities can increase the rate of weathering? Half of all habitable land is used for agriculture. Nasa How Hard Are We Pushing The Land. https://www.quora.com/How-much-land-on-Earth-in-terms-of-percentage-is-populated-by-humans. Ron Nichols/U.S. Further, it is just silly to assume that if I as a human would use a steady route through an otherwise “untouched” area I would “impact” said area deeming it to be a part of your 90%, and in the same breath believe that the area would be magically immune from any other “impact” by any other life-form that would be living within it or any other occurrence that would affect it, such as a volcano or earthquake. This is just 1/4400 the total mass of the Earth, which means that while the oceans cover 71% of the Earth’s surface, they only account for 0.02% of our planet’s total mass. Which to trust? So we could all stand on Rhodes or Mauritius, but not Manhattan (which is less than 13 square miles). At 3.79 million square miles (9.83 million km²) and with about 305 million people, the United States is the third or fourth largest country by total area, and third largest by land area and by population. The thing is, landcover is something that is changing (and our technology to estimate it is improving) constantly, so even fairly recent estimates may already be out of date. The total land surface area of Earth is about 57,308,738 square miles, of which about 33% is desert and about 24% is mountainous. If you need a larger version the file is attached in the lab instructions. Land gains and loses heat much quicker than oceans. Forests cover about 31% of the land on Earth, but, sadly, that number is decreasing at a rapid rate. How much of the land on Earth is covered by humans? Under the FAO's definitions above, agricultural land covers 38.4% of the world's land area as of 2011. Which of the following is the world’s largest biome by area? According to the FAO Global Land Cover SHARE database, produced in 2014, 0.6% of Earth's land surface is defined as 'Artificial surfaces'. It’s unfortunate that you chose to pick out just one sentence from my article and ignore the science that was sitting next to you. Only 3.74% of cells were No Data and filled via human population density on a country-by-country basis. 97 percent is salt water and only 3 percent is fresh water. The third greatest source of water, after (1) oceans and seas and (2) icecaps and glaciers, is ground water, or aquifers. Puerto covers approximately 100 by 35 miles. The first is the more general about 70% of Earth is water while about 30% is land (US Geological Society). All Countries and Economies. Buffalo grazing on rangeland in Crook County, Wyoming. Are you a teacher? Earthquakes can cause tsunamis which can kill hundreds of thousands of people, injuring countless others and destroy decades of human development in a matter of minutes. In the year 2000, estimates suggest that globally, urban land covered somewhere between 700,000 and 3.5 million km2 – but that’s a pretty big margin of error. Land covered by water, wetland and bareland accounted for a relatively low proportion of total land cover in most of the EU Member States in 2015. As you go West- those percentage probably go up quite a bit- Nebraska, Montana, Colorado, Utah, Idaho etc. Most Recent Value. Artificial surfaces include any areas that have an artificial cover as a result of human activities such as construction (cities, towns, transportation), extraction (open mines and quarries) or waste disposal. 30 10 50 Ο Ο Ο 100 25 Question 2 Where are the two ice sheets located today? Being 3500 square miles in size, it is roughly the size of the state of Connecticut. Country . The percentages of earth's land surface can be divided into different types: 20% covered by snow land, 20% mountains, 20% dry land, 30% good land that can be farmed, 10% land doesn't have topsoil. naturally regenerated forests of native species, where there are no visible indications of human activities and the ecological processes are … No matter how you measure it, humans are a SMALL percentage of what goes on on earth. WDI Tables. Subtracting this uninhabitable 57% (32,665,981 mi 2) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land. This figure gives us an estimate of roughly 900,000 km2 of human-covered land worldwide. Our summaries and analyses are written by experts, and your questions are answered by real teachers. I kept in my mind this. The Iran-wide land cover map was generated by processing Sentinel imagery within the Google Earth Engine Cloud platform. It is interesting to note that of Earth's freshwater sources, about 69% is in icecaps and glaciers (NOAA). Just over 2/3 of the Earth is ocean. Question 1 What percentage of Earth's land surface do glaciers currently cover? However, only 10% of land on Earth was considered ‘remote’ – more than 48 hours from a large city. Which land biome covers the largest percentage of land? Findings published in Nature in January 2014 show that warming currents in the North Atlantic adversely affect (1) "sea-ice redistribution" (i.e., shifting positions of large bodies of sea-ice) in Antarctica, (2) melting ice in the southern icecap of Antarctica, (3) a warming climate with (4) increased ice melt in Antarctica. Greenland and Antarctica together hold about 99% of Earth's freshwater ice, which is undergoing significant changes in location and water phase (from frozen to liquid and vapor). By using such imaging satellites as Landsat 5, Landsat 7 and Terra, scientists have the ability to observe large tracts of the Earth's surface in a fraction of the time needed to complete aerial or ground surveys. In 2009, the European Commission’s Joint Research Center published a map in the World Bank’s World Development report, showing that 95% of the world’s population is concentrated in just 10% of the land surface. Or you could take a more glass half-empty view and say that 90% of Earth is covered by humans – either populated or connected with an ever-expanding network of roads, train tracks, highways, farms and industrial land. So in that sense, 90% of the land on Earth is being regularly accessed and therefore impacted by humans. km) Download. Land covers 196.9 million square miles of the planet, which is broken up into 196 countries that are home to 7.125 billion people. (Asked by Lynne). eNotes.com will help you with any book or any question. Earth’s surface is about 500 million km2, but most of that (70.8%) is water, which we’re not really very good at. Featured image from MODIS is in the Public Domain. buffalo grazing on rangeland. I find it very insulting that you would suggest I merely copied and pasted text from elsewhere – I would never plagiarise someone else’s work on my blog, this is a very serious allegation and simply not true.

Both will serve, depending upon your need and aim. The volume of aquifer water is about 5,614,000 cubic miles. forests, grasslands, croplands, lakes, wetlands. Now when I needed this information I started searching and encountered this article. Artificial surfaces include any areas that have an artificial cover as a result of human activities such as construction (cities, towns, transportation), extraction (open mines and quarries) or waste … Besides, do you not realise that we humans are as much natural and a part of earth as anything else on it? Historical land cover data for the years 1500–2005 are based on HYDE 3.1 and future land cover projections for the period 2006–2100 came from four Integrated Assessment Model (IAM) scenarios which reach different levels of radiative forcing by year 2100: MESSAGE (8.5 W/m2), AIM (6 W/m2), GCAM (4.5 W/m2), and IMAGE (2.6 W/m2). It is very telling that you would leave the reader with that as an actual conclusion, which essentially defeats any of the numbers you provided prior to your “glass-half-empty”conclusion. A GIS question: I want to summarize the percent of each pixel type in a raster layer (it's a land use/ land cover layer) in a circle around each point in a point shapefile. Land use Land use vineyards and orchards ) are 3.1% (1.2% of global land area). A tiny, tiny fraction. Leaving 35% untouched and uninhabited by humans. At 3.79 million square miles (9.83 million km²) and with about 305 million people, the United States is the third or fourth largest country by total area, and third largest by land area and by population. Most Recent Year. For years scientists across the world have been mapping changes in the landscape (forest to field, grassland to desert, ice to rock) to prevent future disasters, monitor natural resources, and collect information on the environment. Hot air goes up and leaves the vacuum under it, which is filled by cold air again. Land cover maps represent spatial information on different types (classes) of physical coverage of the Earth's surface, e.g. Land Cloud Cover, which is also included, is determined by calculating the percentage of clouds over land-only pixels in a scene using a mask that discriminates land from water. It seems that caldera is a larger depression than a crater. If the European 60% less factor is assumed, then urbanization would cover 1% of the world's land (1.3 million square kilometers). Subtracting this uninhabitable 57% (32,665,981 mi 2 ) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land. Of course the planet has also been impacted by other living organisms (although I’d argue few if any to the same extent or degree) and by natural forces such as volcanism and tectonics. What is an example of a continental divergent boundary? As of 2020, the global population has risen to an astonishing 7.8 billion. km) Urban land area (sq. Give an example of divergent boundary. Earth's hydrologic cycle, the movement of water from Earth to air to Earth's occupants, keeps the water circulating and going through various hydrologic phases, liquid, vapor and frozen forms such as snow and ice. Livestock takes up nearly 80% of global agricultural land, yet produces less than 20% of the world’s supply of calories (as shown in the visualization). Sorry what I meant to say is that your text was plagiarized by Rithwik. To move air from one place to other it is must that one area is hot and one area is cold at same time. What’s the biggest forest in the world? These volumes are surprisingly close while saline oceanic water bears no comparison at all, with a volume of 321,000,000 cubic miles. Burundi and Rwanda have the highest proportions of anthropogenic land cover at 85.99% and 82.27% respectively. Land use categories of cropland, pasture, primary land, secondary (recovering) land, and urban land, and underlying annual land-use transitions, are included. There are generally two versions of the answer to this question. The amount of water covering the earth's surface is a staggering 70 percent, with the remaining 30 percent being covered by land.However, there is an irony to this fact of there being so much water on earth. This suggests the lower end of the estimates made in 2000 were probably more accurate, and that we’ve still got a long way to go before we hit Seto and colleague’s projections! The zealots included land which is being farmed and forested, but this land is not subject to any kind of contamination. Liberals! While your plan will apparently support 40 billion people, why would we want this? You people are so loony. If The Earth Stood Still What Would Hen Stopped Spinning . km) Urban land area where elevation is below 5 meters (sq. Sea, Fertile Land, Desert, Hills and High mountains are essential part of nature’s echo system and nature’s cycle of seasons. Your email address will not be published. According to the FAO Global Land Cover SHARE database, produced in 2014, 0.6% of Earth’s land surface is defined as ‘Artificial surfaces‘. i would like to know total land area usable in which how much human worldwide cover the area and how much is balance to be utalize hope my query is clear. The second is the more specific 71% of Earth is water while 29% is land. It does not include land that is predominantly under agricultural or urban land use" (FAO 2015). The meta-analysis found that the largest rates of increase in urban landcover were seen in India, China and Africa, while North America experienced the largest total change since 1970. https://www.epa.gov/sites/production/files/signpost/cc.html. The underlying dataset for this landcover product is the IGBP layer found within the MODIS annual landcover product (MCD12Q1). Online tool for visualization and analysis. The FAO GLC SHARE data shows that 12.6% of land is categorised as cropland. Start your 48-hour free trial and unlock all the summaries, Q&A, and analyses you need to get better grades now. The amount of water located on Earth is enough to cover the entire land mass of the contiguous United States to a depth of 107 miles. the percentage that covers the earth's surface that is land is 30% What covers 30 percent of earth? Though humans have been modifying land … This means that what we eat is more important than how much we eat in determining the amount of land required to produce our food. Landcover is one key way that we can measure how much of the terrestrial environment has been covered by humans. For instance, while warming temperatures from greenhouse gases cause greater ocean cloud cover, counteracting some of the rise in Earth temperature, the warming is also raising sea levels and making ocean waters more acidic affecting saltwater flora and sea creatures. DataBank. Heat and air travel process causes rain. Already a member? What are the 4 major biomes? Understanding the land cover of Earth aids policy makers involved in natural resource management. Ultimately there is no one right answer to this question since there are many ways to interpret it – I tried to present a number of different ways of looking at the same question and provide some kind of answer to each. True deserts cover about 14 percent of the world's land area, or about 8,000,000 square miles (20,800,000 square kilometers). Dynamic land cover maps include transitions of land cover classes over time and hence captures land cover changes. Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. Do the oceans cover 75 percent of the entire Earth? The costs of a big brain outweigh the benefits, Sedentary hunter-gatherers domesticated mice, a science blog, covering topics ranging from medicine to conservation, and from evolution to technology. While land cover can be observed on the ground or by airplane, the most efficient way to map it is from space. Snow and Ice Cover on Earth. The total land surface area of Earth is about 57,308,738 square miles, of which about 33% is desert and about 24% is mountainous. km) Rural land area where elevation is below 5 meters (sq. This site uses Akismet to reduce spam. How Much Land Is There On Earth/In The World In Total? This question is an interesting one because, when my friend asked me the other day, I could tell her confidently that not only did science know the answer, science had multiple different ways to quantify that answer, but that I had absolutely no idea what it was. I’ve reported the answer to Quora as plagiarised. To create passages from water ways to deserts we’d be destroying natural habitats of species living in the desert and disturbing those of species who live in the water, effecting their migration and food sources and further deteriorating their population. In fact, the earth's surface is covered mostly with water, with land areas forming a very small percentage. Not only that, but of that 2.5 percent, more than two-thirds is locked away in glaciers and not particularly able to help meet the growing demands of society. Using data from 1970 to 2000, the researchers then tried to project future urban land cover change – their results predict that global urban landcover will increase by a further 1.5 million km2 by 2030. It’s unfortunate that you don’t understand the discrepancy. That leaves between 3.5% and 2.5% distributed between all Earth's freshwater sources, including water vapor in the air and water in occupants of Earth (US Geological Society). The satellite image was classified based on land-use type using ERDAS software, and the land utilization map was manually digitized and grouped into land-use type using Map Info software. Both the satellite image and the map were compared to see the changes of percentage and total area of land cover. It does not include land that is predominantly under agricultural or urban land use" (FAO 2015). Rangelands thus occupy about 40–50 percent of the land area of the Earth. For this purpose, over 2,500 Sentinel-1 and over 11,000 Sentinel-2 images were processed to produce a single mosaic dataset for the year 2017. Land covers 30% of the Earth, while the Oceans take up the remaining 70%. All you have to do to get a correct answer to this dispute is to look out the window on a flight from east to west coast of North America. The percentages of earth's land surface can be divided into different types: 20% covered by snow land, 20% mountains, 20% dry land, 30% good land that can be farmed, 10% land doesn't have topsoil. DataBank. The entire population of the earth can stand on Manhattan Island with room to spare. Over half-way to this prediction, where are we now? CSV XML EXCEL. I don’t think the Manhattan fact is true. Land covers 196.9 million square miles of the planet, which is broken up into 196 countries that are home to 7.125 billion people. Forests cover 31 percent of the world’s land surface, just over 4 billion hectares. Hills & mountains help the wet air to rise up in order to increase density of clouds, which ultimately rains. Space Place... in a snap!How much water is on Earth?Earth is special because it has so much water. Seriously? “90% of Earth is covered by humans”! Forests cover 31 percent of the global land area. Describe the present condition of the 'mother earth.'. I’m not sure. Land covered by water, wetland and bareland accounted for a relatively low proportion of total land cover in most of the EU Member States in 2015. How do we know humans are causing climate change? Describe the earth's present condition. km) Download . 10% of the world is covered by glaciers, and a further 19% is barren land – deserts, dry salt flats, beaches, sand dunes, and exposed rocks. 1992 data are primarily based on unsupervised classification of Landsat data, while the rest of the images rely on the imperviousness data layer for the urban classes and on a decision-tree classification for the rest. However, only 10% of land on Earth was considered ‘remote’ – more than 48 hours from a large city.”. Area of land: 148 326 000 km2 (57 268 900 square miles), this are 29% of the total surface of Planet Earth. Governments are also beginning to protect marine areas known as Marine Protected Areas (MPAs). The top 3 countries with the most total cultivated land right now are 1. 1 This leaves what we call ‘habitable land’. Annual data on age and biomass density of secondary land, as well as annual wood harvest, are included for each grid cell. So ignoring oil rigs and the occasional cruise liner, we’re only talking about a total possible land surface to cover of roughly 149 million km2. Why is it important to study rocks? The totality of Earth's water is comprised of water in the oceans, water in the air, water in frozen icecaps and glaciers, water in underground aquifers, and water in lakes, rivers and ponds. How much farmable land is left of Earth, and it’s suitability – There is still some farmable land left on Earth, but there could be challenges in accessing it, challenges in trying to farm on it. This includes the land occupied by cities, towns, and commercial enterprises. Kenya contains the greatest percentage of land still in a natural state (82.65%), mostly within the nation's arid north. The only countries which recorded shares in excess of 10.0 % were Sweden (19.0 %), Cyprus (16.8 %), Finland (15.9 %) and the Netherlands (12.4 %). Seto, Fragkias, Güneralp, and Reilly (2011). Maybe some humans have trekked through various parts but they are not living there. Humans have disturbed a very small portion of the earths surface. ©2020 eNotes.com, Inc. All Rights Reserved. If the water above ground, saline and freshwater, on Earth is measured by volume, the total volume would cover about 1,064 miles in diameter and more than 335,000,000 cubic miles. Which biome covers the largest part of Earth? 30 10 50 Ο Ο Ο 100 25 Question 2 Where are the two ice sheets located today? The interesting thing is that the percentage of water on Earth does not include only the obvious sources of water, like oceans and lakes, but less obvious sources as well. Oceans and their influence on earth have a much greater impact – try to stop or create a hurricane, typhoon, cyclone, monsoon, etc. Curious Meerkat uses cookies. United States, 3.
