War contributes greatly to global warming which shouldn't surprise us. All those bombs going off all those rockets all those planes and helicopters. All that fuel of various kinds being used. It pollutes the air and water of this very fragile and interconnected planet.

Companies that pollute should be taxed so that a product's cost to society is reflected in the price of that product.

So basically my view is I don't want to support the exploitation of animals and within reason I will do what I can to avoid it but it's not like it's a religion for me. It's not like I consider I'm polluted if somehow some bit of milk or cheese or something passes my lips.

I live in Los Angeles which is the second most polluted city in the world and I wake up in the morning to dirt all over my window.

If we pollute the air water and soil that keep us alive and well and destroy the biodiversity that allows natural systems to function no amount of money will save us.

Prayer does not use up artificial energy doesn't burn up any fossil fuel doesn't pollute. Neither does song neither does love neither does the dance.

For 50 years nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task and most of the cost of making safe sites that have been polluted half-way to eternity.

Just as there's garbage that pollutes the Potomac river there is garbage polluting our culture. We need an Environmental Protection Agency to clean it up.

Public discourse has been polluted now for decades by corporate-funded disinformation - not just with climate change but with a host of health environmental and societal threats. The implications for the planet are grim.
