You are seriously saying you can do the sums on the back of a napkin? And that entire fields of science are incorrect (despite their evidence) because you simply think so?
The evidence you speak of for increasing crop yields is nonsense, as you are ignoring the problem of lands in climates suitable for agriculture not being where our current infrastructure is, and the soil in those places being completely unsuitable for plants. Also that our main staple crops lose nutritional content with more CO2, meaning those improved yields are a wash, would the crops be able to grow in the first place.
Just admit it - you don't know what you're talking about, but the thought that you might have to change your lifestyle scares you. That's fine. Don't pretend to be informed, as you are making it patently clear with every nonsensical, gibbering post you make that you really have very little clue.
