One of our real pollution problems comes from farm runoff. The best way to mitigate the need for fertilizers is to increase atmospheric CO2. Our plants are starving at 400ppm. Most cereal crops stop growing at 350ppm and die at 250. If human beings are going to continue to multiply, fill the Earth and subdue it, we are going to need a warmer, wetter climate with a much denser concentration of atmospheric CO2.
The earth stopped greening in the 1990s. Out in the real world, further increases in CO2 are not increasing plant growth. Hence, your premise fails. One wonders then how the world was growing cereal crops at 280 ppm. Your science seems to have some problems.
