Why do people only live on earth?

Answer 1

because some places they cant live like where desserts,high mountains and ice covered land is

Answer 2

A large percentage of the Earth's surface is ocean, and thus uninhabitable by humans. Large expanses are ice cap (the Arctic, Antarctica, Greenland) and are also not suited to large human habitation (Antarctica has no permanent human population) and other areas are desert, which again can only support very small numbers of humans and none at all in some areas. Other areas are mountainous - humans cannot survive for long at very high altitudes without modern equipment. Other areas may not be able to support farming for a variety of reasons, and so are unsuitable.

Answer 3

Well some of it is too wet, (though the fish think its OK.)

Some of it is too cold, (though the penguins and polar bears think it is OK.)

Some of it is too high.

Some of it is a desert.

You get the idea, some of the earth is not suited to easy living.

Climate as it relates to food production. Ease of travel for commerce. Availability of services, particularly medical and education.

One of the biggest reasons is because no one is willing to invest in the use of technology to make better use of the Planets so called "uninhabitable" space.

Just like the Great Plains here in the US that suffers whenever there is a drought and causes lower output from farms and agriculture in general. The idea of desalinization and putting pipelines from both the Great Lakes and the Gulf of Mexico could turn the United States into the largest supplier of food on the planet. Just as more exploration into natural energy sources has been basically cut off except for Natural Gas, we keep ourselves dependent on foreign oil and other energy resources keeping the prices very high and the willingness of big companies investing in such things that would benefit everyone.

Answer 4

Well we are the only planet with water and air

Answer 5

Beacause around aquarter or a half of the Earth is water. Think about the desserts , we cannot live in a type of ecosystem like that

Answer 6

earth is 75% water and about 16% of earth surface is Uninhabitable (desert)

Answer 7

the earht is mostly made up of water
