Do you mean how am I showing a different behaviour to despair and disinterest?
Firstly, just because I think we should not be doing one thing, doesn't mean I am doing the other thing perfectly. I am as human as the next person.
I'm not massively engaged with politics, climate change, etc, but I have a family and daughter. Caring about people, especially younger people, is a way that I don't write off the future. I also really enjoy wildlife and being outside, and support two different conservation charities. My wife supports a couple of different children's charities. It's not a lot (I'm not activist hero), but it's something.
Of course, if someone wanted to say that the above amounts to nothing, and I'm a hypocrite, then they are welcome to think as much.
