Human population and efficient conservation: Are humans playing ostriches and rabbits?

The environment is currently under aggravated threats because of climate change, mainly due to increasing resource requirements to maintain the always growing human population. While multiple causes are generally pointed at, and responsibilities bounced back and forth, a clear first step to remedy to the problem would be being responsible about the number humans of Earth. The difficulty inherent to curbing population growth is the cross-culture and world-unifying taboo on any kind of population control. Clear international recommendation will alleviate population growth and enable environmental conservation. In addition, ameliorations in family planning and abortion rights, along with providing resources for education, would significantly curb population expansion and lessen the threats from climate change and resources depletion.
