Maybe they won't? Maybe you will have to plant trees that can live there. The article mentions that while the Amazon could become barren by 2500, the American midwest may be tropical. Guess what kinds of plants would grow there? And crops would grow closer to the poles. So Canada and Russia would grow much of the world's food.

That's not ideal, but I'm guessing that 480 years is enough time for humans to adapt. Anyway, there have been several articles on here saying that global plant growth and the number of trees have increased over the past century based on NASA's satellite imagery and counts from 50,000 locations. So while your area may be losing trees, other areas are gaining them. Nature adapts and changes.

That isn’t a plan, it’s an appeal to “life finds a way.”

Exactly! I’m totally confident that life will find a way and Earth will be fine (no matter how badly we hurt the environment)… Not so confident however that the life that finds a way will include humans.

I don't see many people arguing that climate change will end life on Earth or something. But a mass extinction could mean, for example, that everything in the ocean larger than your hand dies. It could mean, for example, that lush forests full of a myriad of insects, birds, mammals, turn into wastelands. It could mean the extinction of huge swaths of animals, like goodbye raccoons, bears, squirrels, bison, wolves, deer. Or goodbye lizards, turtles, snails, snakes. Maybe it hits a link lower in the chain first, like bees, ants, and whole towers of the ecosystem collapse down from there.

When the dinosaurs were obliterated by the Chicxulub impactor 65 million years ago, 90% of land species also disappeared, never to reappear again. It took millions of years for mammals to emerge as the "victors" of that huge extinction event.

The viewpoint you espouse is just so hollow and frankly, repugnant. The thought that we can just stupidly smash incredibly intricate towers of evolution's genius, flub our precious time on this Earth to move from ignorantly and unintentionally knocking them over to actively raising a sledge hammer to them, justifying it to ourselves that "it will all be fine". Such a destructive attitude ruins everything for everyone. It's flippant and stupid, But it's ultimately, tragically, self-destructive.

It doesn't matter what we think. It's our actions.

I think we agree — I quit eating meat entirely a couple of years ago because I feel so strongly about the environmental concerns.

Sorry if it didn’t come through in my comment: I was just being a little sarcastic and building off the GP comment, trying to reiterate that “life finds a way” is pointless to try and argue, since human life is much more fragile than life in general (and I tend to value human life).
