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.
at this point I think the biggest single CO2 source from me is my electricity usage, and I have no direct control over my electricity source. it’s not like I can call up the utility company and tell them to only send solar, wind, and nuclear power to my house.
You may not, but some actually can. My utility has renewable programs, and they explicitly are for over and above government requirements.
