"90% of people live on only 10% of earth's land"

This is what some people says about overexploding population of 8 billion and that there is still 90% land is remaining...cheers! 

Really? the real info is that-only 40% of land is human habitable, from which we had took up the 10% already.

so you can say OK!, we still have 30% of remaining.

Hope you will know there is not only humans on earth

we can't grab other *species space*, as we already started taking up theirs, 

we must control our population otherwise ...fhew**
