It's called shooting yourself in the foot. We did it to ourselves... just some of us are closer to the front of the line than others.
Population Overshoot is the core cause of the situation. Close to every problem we encounter can be traced back to simply too many people for the earth to support. Some areas are blessed with more resources (or rather, just haven't been stripped yet) and instead of living within the constraints of our environment, we continue to push the numbers.
In the end, Nature/Science has the last say. Whether it is famine, disease or war, saving/rescuing a million today will mean there are an additional 20 million more down the road, that will need saving again, in a world with fewer and fewer resources.
In history, when populations got too big, we simply moved down the road. When we stripped the soil of nutrients, we moved on. Now there is no more road to use.
While I may appear cold and callous, this situation has been forecasted for the last 50+ years... and we choose to ignore the science; a finite world has finite resources. Overshoot, in population, has toxic side-effects... not enough food, stripped soils, degraded water, climate change, rising oceans, loss of lands, etc.
It took all of the earth's history to reach 1 billion people in the 1800's. It took less than 150 years to reach 7 billion people. Think about the consequences of that. While Genocide is a side effect of climate change, it is only ONE of the many ways we have committed genocide for all of us.
Until there is a rational plan to deal with the consequences (how about birth control to start with)... we just delay the inevitable and condemn even more people in the end. Just think about it.
