There are a lot of people in the animal rights movement who can be very passionate and aggressive, and I applaud people's passion, but when people are judgmental and aggressive, all you end up doing is getting other people to turn away in irritation. To change people's minds, you have to respect the people you're talking to.

You have climate change and antibiotic resistance which are two of the biggest horses of the apocalypse, and they're basically breathing on our necks, and there's no political will or effort being expended to deal with them.

Being a vegan is pretty easy these days, as almost every town and city has health food stores and vegetarian-friendly restaurants.

Since I was really little, I've just always had an obsession with, not just science fiction, but science and space. And also because as time passes and the more advanced science becomes, the more interesting it becomes.

Over time I just realised the world is a very complicated place, and there is not a single structured belief system that adequately and comprehensively describes every aspect of our existence. So that is my new approach to life and spirituality - I don't know anything, except on a very naive and subjective level.
