And when you get large numbers of people living in land that is not that fertile, particularly when you cut down trees, and you leave the soil open to the wind for erosion, as desperate populations cut down more and more trees, so that they can try and grow food for themselves and their families, what's going to happen?
A kad imate velik broj ljudi koji žive na neplodnom tlu, pogotovo nakon što posiječete drveće i ostavite tlo otvoreno utjecajima vjetra koji stvaraju eroziju, a očajno stanovništvo i dalje sječe sve više i više drveća da bi poljoprivredom prehranili svoje obitelji, što će se dogoditi?
