You make some good points, particularly about the cruise ships, private yachts, and private jets - which should be banned long before anyone starts thinking about reducing meat consumption.
I would question whether it's all due to consumption or whether some of it is due to manufacturing of goods which aren't made in Africa or other places. People can only use just so much. For example, there's 7.3 billion cellphone users in the world. (
3.12 Billion More Phones Than People In The World!.). They're not all from the West. But if there were fewer people in the world, all the resources used to manufacture these devices could be conserved exponentially.
Same with cars:
Even if it's uneven like this, fewer people would mean fewer cars and decreased emissions.
When MIT made their doomsday prediction in 1972, the world population was less than half of what it is today. The world has never seen this many people at any one time.
I agree that the West should consume less, particularly those at the top levels of society. But I will never accept rationing imposed on the little people until the bigshots put their money where their mouth is.
To be honest, I think the people of Africa and other impoverished areas of the world should be able to enjoy the luxuries and benefits of these technologies. They should not be denied either.
The capitalists created this situation, so if they can't supply everyone in the world with the same amount of stuff, then they'll have to admit their mistake. They'll have to admit that they were short-sighted and foolish - and that they really didn't know what they were doing all along. They'll have to admit that they are unfit to offer any opinions or influence over public policy - and they will have to yield to the socialists who should take over and fix this planet. But the last thing they should ever be doing is telling the common people to consume less meat.
