Nice cherry picking, the next paragraph of the wiki says:

This type of argument is sometimes used as a form of fearmongering in which the probable consequences of a given action are exaggerated in an attempt to scare the audience.[citation needed] When the initial step is not demonstrably likely to result in the claimed effects, this is called the slippery-slope fallacy.

You think your assessment that humans are a scourge on the planet is objective and clear, but you miss your own anthropocentric blindspots. Like it or not, your stance is not unique, on the contrary many humans also question the direction our species is going.

The withering criticism of human activity by yourself and the many others like you is simply evidence that humans are *not* wantonly devouring the planet with no thought for the future, unlike the cricket plagues you liken us to.

Whether that is sufficient to save our society remains to be seen of course.

You are using your human value system to declare humans unworthy. This is a human thing to do. No other creatures reflect on the impact their existence has on the environment. Viruses don’t. Crickets don’t. Not even the planet itself, nor the entire universe, cares whether humans even exist or how they carry out their lives.

It’s only humans who have evolved a brain capable of making such assessments and using that to inform their behaviour. Can we use this power to rise above the bloody law of nature? Can we create a world that is fair and just, even in an uncaring universe built on the cold unbreakable laws of physics?

You probably acknowledge that you’re using your human value system to judge the performance of humanity as a whole. We have evolved to have these concepts of good and evil because they help our tribe to grow and flourish - and you can’t deny that the human tribe has grown and flourished. So your values - including your ability for introspection and self-criticism - are a successful evolutionary adaptation which has helped your species grow and to dominate the world. So I want to thank you for being a successful organism. Well done.
