When we look for global warming causes we should look to ourselves. The problem is that everyone of us, wakes up everyday with needs for food, water, energy and on top of all that we add to the global CO2 problem by driving our cars and emitting even more CO2. Industries have to push the planet's carrying capacity to the limit, because all those people need food, shelter, clothing. This is related with severe CO2 emissions and so we end up in a killer loop. We need to balance the quality of life between the rich and the poor, at the same time, hoping to balance the family size between the rich and the poor. It's the only way we will ever make it.
