Nice ideas, but factually completely wrong.

The real reason why people should compose or better whole cities should, is because the nutrition in the green waste should go back in circulation which they wont do if they end up in a landfill/waste incineration.

The greenhouse gasses reasoning is bogus it decomposes anyway Modern landfills are also used as energy source where the worst kind of greenhouse gases are burned and turned into less severe CO2.

The space argument is also nonsense. There is plenty place on earth the real problem here is that moving trash is expensive hence poor cities are surrounded by garbage mountains.
