Human impact has pushed Earth into the Anthropocene, scientists say

So along with other factors, the 300 m metric tonnes of plastic humans generate each year, is contributing to a new geographical epoch.

I found this on the Guardian website.

It almost makes my small effort to buy less plastic seem a bit pointless, but I think that's the point. These global issues seem so big it feels out of our control. But consumers as a conglomerate group have a lot of power. When more and more people refuse to buy things packaged in plastic manufacturers will adapt.
