Yes you are very right about all of that. There's a lake near where I live that bubbles up methane. People thought it was a hot spring since it never freezes and a guy about blew up when he lit a cigarette when they went on the ice to to the holes to check the water temperature.
I just read a study about how much CO2 is released by rock .that contributes to atmospheric CO2 CO2 was a major part of the formation of the planet, it's infused in everything. When you turn on a water tap it releases CO2. CO2 gets trapped in water in several parts of the water cycle whether it's caught in rain or snowfall, or from soils, it ends up in aquifers and rivers. It's a natural part of our ecosystem, and it is absolutely essential for life. Plant life requires a minimum of 300 ppm CO2. Climate changers say the optimum CO2 level is 350 ppm which is precariously close to the minimum. OSHA doesn't get too worked up until people are exposed to 10,000 ppm. The propaganda has been puked out for so long, I don't think the trajectory will be changed. I did most of these memes for a presentation and posted them here just for farts and giggles. Great comments, thanks.
