Carbon dioxide is the greenest gas
I had a CO2 generator in my garden back in the day, and it really helped yields.
Carbon dioxide comprises a fraction of 1% of the atmosphere, and provides most of the mass in plants. Most of the mass in plants, apart from water, comes from carbon dioxide, not soil nutrients. I’m not saying we have no environmental problems, not at all, but don’t accept carbon taxes or carbon credits or anything like that, it’s a mechanism for control, no more.
Also, I live in La Paz, which sits in a double bay tucked off the Sea of Cortez, or Gulf of California, which is already relatively calm, so the water is super calm and comes right up to the main road. It hasn’t risen in 500 years, and isn’t rising today. The snorkeling and diving are great here, and it’s a good place to bring kids because the water is calm and you can walk out far in a lot of places, the beach slopes gently into the water.
