This is a very weird paragraph. Forgive me if I don't understand properly, but let's look at this carefully:
> The climate will change. That's completely natural
The climate does change naturally. It also changes due to artificial reasons (unless you consider human pollution to be natural, but that's just word semantics. For now, lets call human-caused climate change "artificial").
So no this is not completely natural. Our activities have had intense repercussions on our planet's climate in a very artificial way.
> and I can't see a reason to stop it
Really? You can't see any reason at all? If we don't stop polluting and heating up the planet, it's possible that hundreds of millions of people will suffer and perhaps die. Worst case scenarios have terrible food shortages and awful fresh water problems as rain patterns shift and change. Even if none of this happens there is absolutely that risk. How can you say that you see no reason to stop the human-caused climate change?
> (honestly I think it's impossible).
This makes zero sense to me. We started changing our climate a long time ago and didn't even notice. We're still changing it now. What makes you think it's "impossible" to start going the other way? Dude, we can drive electric cars on the moon. We can develop technologies to help regulate our climate here on Earth just fine.
> Humans and other animals will just adapt and the evolution will continue.
Not so fast. While evolution will definitely continue, there already are mass extinctions happening due to climate change. We're changing things far faster than most species can react to, far faster than evolution can handle.
Life on Earth will most certainly continue and evolve for many millions of years into the future. But at what cost? We don't need to kill off millions of species just 'cause it's cheaper to burn fuel than use other methods.
Let's try to keep as many currently-alive species going as long as we can, yeah? What's the harm in that?
