Things won't get any better till everybody is honest about it.
I hate to say it, but things will never get better. There is no political will anywhere in the world, other than the few countries who are about to disappear under rising sea levels in the next decade or so.
The people of the UK may say they are all for doing something about it, but the party who tries to introduce the necessary legislation would be out on their ear so quick.
Imagine for a moment that the Greens have formed the next government and they have levied a charge of £1000 per seat on all flights into or out of the UK. And immediately Mr and Mrs Bloggs and their two kids see their package holiday to Tenerife go up by £8000. Do you think the greens would be elected next time?
Why do you think Fuel Duty has been quietly shelved, instead of the planned annual rise? Or a law is introduced that all diesel and petrol car (including hybrids) must be scrapped when they reach 10 years of age and from 2022 the only vehicles we can buy are electric or hydrogen fuel cell, irrespective of the state of technology or limited infrastructure!
And, God forbid, that from 1st January 2020 we must all turn vegetarian or vegan, as the raising of animals for food is prohibited and importing meat is illegal too. Talk about Prohibition. We would be fighting on the streets.
As long as there is a profit in CO2 production, it will continue.
