If by "we" you mean Trump supporters & Trump himself that may actually be correct. Unfortunately there are Boomers who hold the same wildly ignorant views Trump does about exercise & lie to themselves about their weight problems as he does instead of taking sensible care to be able to maintain better health. It's a similar concept with taking care of the planet. No, Earth isn't going to "die" like the way all humans will but the damage inflicted on it due to ignorance, laziness, indifference is tangible.
Thankfully in all regards I'm not a part of that "we" and neither is AOC. Maybe try putting down that brandy & Coke with a lime & picking up an actual book on environmental science. Trying learning about facts. AOC never said we only have 10 yrs. She talked about how ppl of my generation, people of her generation, the ones who are going to live on Earth for a lot longer than the Boomers, have come to her concerned. A quote of hers where she was referencing those concerns of young people who've actually bothered to do things like, you know,
read reports from the world's leading climate scientists, have expressed to her then got butchered from context. Which lead to the sort of people who do their "research" on sites with as much credibility as a fortune cookie mocking what she said & dishonestly misrepresenting it.
Thanks again for writing about how ashamed you are of Christians. You keep reminding me of how that's something we have in common.
