It just amazes me that people seem able to be pro-migration and pro-environment and seriously believe there is no contradiction between the two. Those people that move are going to need somewhere to live, work, go to school, shop, etc etc. All of that requires constrution, which is massively carbon intensive. Less migration means less of that construction, and also avoids the negative impacts on both the source and the destination. Far better to have people with their own people rather than forced to the other side of the world. And we get to maintain the distinctive cultures of the world.
I love diversity: that's why I think we should stop trying to destroy it.
