"Population Growth" I presume you mean "human population growth"- aka at 7 billion and counting. that's an intraspecies issue that needs to be solved. it collides head-on with:

"Climate Change" We are going to need to re-learn how to produce food locally, and as mentioned before by others: permaculture, not industrial technology, holds the key. The basic lesson of any polluting activity that destabilized our natural world in some fashion is that our activities need to be in harmony with natural cycles. General channel herbicides that affect the uptake of soil nutrition by plants (glyphosate, for example) are not things that should be used as they get into the water and eventually all plant life must deal with their effects, stunting any cultivars not engineered to withstand these effects. What is a "weed" to one person is "green manure" to another that builds soil. It may be a protector plant that draws insects away from crop cultivars, it may have symbiotic beneficials effects we are un-aware of. We need to step out of the lab and into the field and learn about the complex interactions of the real world if we are to truly learn how to live in harmony with the planet we are from and live upon.

Why do we think and behave as if we are not an animal species native to the surface of earth?
