Yes, its a big part. I love trees and animals much more than humans and to see the natural world suffer and die is very painfull. Here in Sweden we have no old forrests left, everything is clear cut and the weather is getting hotter, the groundwater sinks rapidly and the insects are almost completely gone.
The sea is full of big dead zones, the fish floats dead in many lakes and where are the badgers and the hedgehogs?
Climate change and the pollution are going to kill us all, not only the other animals.
Look at pictures from Syria, thats a climate change war, thats our future.
