It is difficult not to be cynical about our chances or slowing down, let alone reversing, the fact (note 'FACT', Donald Trump) of global warming when the biggest consumer societies on earth are paying lip service to it and the biggest polluter on earth shows no sign of changing.
I always feel uncomfortable when western nations preach to emerging nations about how bad their behaviour is. How soon we forget that 200/250 years ago the UK started industrialising without any concern for environmental damage, yet we criticise others for doing exactly the same now. And yes, I do understand that the world is (or should be) aware of the consequences now, whereas in 1750/1800 the UK couldn't have been.
Nevertheless, the genie is now out of the bottle. Indonesian rain forests are disappearing because of OUR need for palm oil in virtually every product.
We CAN make local differences by reducing use of plastics etc etc etc, and every little helps, but the overall direction seems to be that we're screwed. Nearly 8 billion of us today, and increasing exponentially. Over-population was always the ticking time bomb, and that's not going to change.
