She created Curious Meerkat in 2009, and has also written for a variety of publications including New Scientist, BBC Earth, Science, Nature, Mongabay, and The Scientist, as well as contributing to several books.. She completed her PhD in 2013 on the social behaviour of dinosaur ants. As of 2020, the global population has risen to an astonishing 7.8 billion. 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. Sorry what I meant to say is that your text was plagiarized by Rithwik. I would agree that the percentage of 10% is untouched by humans/uninhabited is extremely low. According to the FAO Global Land Cover SHARE database, produced in 2014, 0.6% of Earth's land surface is defined as 'Artificial surfaces'. If you need a larger version the file is attached in the lab instructions. Being 3500 square miles in size, it is roughly the size of the state of Connecticut. Both will serve, depending upon your need and aim. All Countries and Economies. 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. 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. The United Nations (UN) has set a goal for 10% of the world's oceans to be protected by 2020. How do we know humans are causing climate change? I’m sorry you didn’t enjoy the article. Rural land area where elevation is below 5 meters (% of total land area) Urban land area where elevation is below 5 meters (% of total land area) Land area (sq. How Much Land Is There On Earth/In The World In Total? 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is changing (and our technology to estimate it is improving) constantly, so even fairly recent estimates may already be out of date. Humans have disturbed a very small portion of the earths surface. “90% of Earth is covered by humans”! km) Download . There are generally two versions of the answer to this question. Nasa Usgs Mission Helps What Is A Forest. Approximately half the forest area is relatively intact, and more than one-third is primary forest (i.e. DataBank. The correct figure for the percentage of the earth’s land mass which is actually occupied by humans is .03%. You can fly for a long time and hardly see a sign of human existance along many parts of the continent. Volcanos probably have a greater impact despite the infrequency of catastrophic eruptions – they shut down travel and pollute the ocean and harm humans. Some folks in the know have estimated that Urban land use at this point is closer to 2.4% of the earth’s land area and they speculate that the 3% figure is being used to cover the uncertainty. Ultimately, my conclusion is that there is very little of the Earth (whether you read that as the planet’s surface, the land or the sea) that has not been impacted in some way by humans. Dynamic land cover maps include transitions of land cover classes over time and hence captures land cover changes. I say that because this would have to be a consideration in your “conclusion”. What’s the biggest forest in the world? CSV XML EXCEL. Other lands are any lands not arable or under permanent crops; this includes permanent meadows and pastures, forests and woodlands, built-on areas, roads, barren land, etc. 71% of the earth's surface is covered with water; 29% is land. Nasa How Hard Are We Pushing The Land. Burundi and Rwanda have the highest proportions of anthropogenic land cover at 85.99% and 82.27% respectively. 95% of the world's population is concentrated on just 10% of the world's land; but only 10% of the world's land area is classified as "remote" or more than 48 hours from a large city. 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.

Learn how your comment data is processed. Why is it important to study rocks? 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. 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). 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. Land cover Land cover refers to the physical surface of the earth, including various combinations of vegetation types, soils, exposed rocks and water bodies as well as anthropogenic elements, such as agriculture and built environments. 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. Under the FAO's definitions above, agricultural land covers 38.4% of the world's land area as of 2011. Protecting 17 Percent Of Earth S Land Could Save Two Thirds Plant Species.

Tracts of land around the world have been designated as protected areas due to their natural, cultural, or ecological value. In all regions, urban land expanded either faster or equivalent to population growth rates, suggesting our societies are also becoming more expansive. 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. 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. More than 68 percent of the planet's fresh water is largely inaccessible, located in glaciers, ice caps and permanent snow. 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. Most of you wouldn’t know true science if it was sitting next to you. We simply do NOT know the answers to even apparently “simple” questions that “can” (might) be answered by “science.”.
