We have big box stores for pets.
We have semi trucks burning diesel to bring pet food and pet supplies to all parts of the world.
We devote some amount of farm land and livestock to feeding those pets.
It’s interesting when people suggest to reduce global human population but I have never heard anyone suggest to reduce pet populations as a method for combating climate change or for simply reducing resource usage.
The worldwide dog population is estimated to be 900 million.
There are 600 million to 1 billion cats living in the world today.
I think quality of life is an important point. I know it’s selfish / narcissistic of me, but the main reason to stop climatic crisis is to improve people’s quality of life. The planet will keep turning and life will survive in some form, despite our best efforts. The rest of the solar system, galaxy, universe, won’t even notice. But humans on earth will notice. And if we are destroying quality of life to stop the climate crisis, what’s the point?
(Of course, changes are needed and some quality of life will be lost for the net gain of not dying slowly in an uninhabitable world, but I feel like the companionship of pets is a big deal to some people but a very small cost climate-wise)
