Within only three weeks, the world population will hit 7 billion according to the United Nation Population Fund. Together with rapidly increasing consumption, this of course means that our impact on the planet is greater than ever: we destroy rainforests that accommodate some of the most species rich ecosystems, (so called biodiversity hotspots), we create lakes through construction of massive hydroelectric dams, only to destroy others through over extraction of freshwater. We already caused the climate to warm by around 0.6℃, and are well on the way to emit the trillionth tonne of carbon which would mean being committed to a 'dangerous', 2℃ warming. Carbon in the atmosphere of course not only implies warming and changing weather patterns, but also has the potential to impact marine life through causing ocean acidification, and affects the global carbon cycle. In short, we generate global environmental change.
