about 1/3

>> "about 1/3"?! Who wrote that? 70.8% of the earth's surface is water. If desert is a third of the planet, then there's absolutely nowhere left for humans and animals to live. I'm pretty sure there are some trees still left on the planet. Desert is defined as either land that has less than 50mm rain each year or land which cannot sustain life. This includes Antarctica. 29.2% of the earth's surface is land. About 25% of the earth's surface is desert. Which leaves only 4.2% of the earth's surface as inhabitable and to be shared by 6.75billion people and countless billions of animals. >>>>> The person probably meant that about 1/3 of the earth's land surface is desert. Making it about 10% of the total surface of the earth as water is around 70%.
