Ecological doom-loops: Why ecosystem collapses may occur much sooner than expected
phys.org
Around the world, rainforests are becoming savanna or farmland, savanna is drying out and turning into desert, and icy tundra is thawing. Indeed, scientific studies have now recorded "regime shifts" like these in more than 20 different types of ecosystem where tipping points have been passed. Around the world, more than 20% of ecosystems are in danger of shifting or collapsing into something different.

an ecosystem predicted to collapse in the 2090s owing to the creeping rise of a single source of stress, such as global temperatures, could, in a worst-case scenario, collapse in the 2030s once we factor in other issues like extreme rainfall, pollution, or a sudden spike in natural resource use.

There is no way to restore collapsed ecosystems within any reasonable timeframe. There are no ecological bailouts. In the financial vernacular, we will just have to take the hit.

    We already seen the crab ecosystem by alaska collapse. Overfishing and warmer waters killed most of them off.

      While your probably right, technically, i dont think they ever found the bodies, as you would expect with a large die off.

      My optimistic side wants to believe they relocated…but I suppose either way, it still means thier environment collapsed.
