| > Fossil fuels can't just run out because they are produced continuously They can if your rate of consumption is higher than the rate or production. Also this is irrelevant as the objective is to reduce their consumption. > Carbon dioxide is good for the plant life I think it is safe to say we are already well equipped with it. Also, as per you next point, natural production yields enough of CO2 to sustain the life, which is proven by the fact that this life exists in the first place. > Vulcanic eruptions all over the planet release three orders of magnitude more CO2 than all of humanity combined over a period of one year A quick fact checking yields these numbers: volcanoes produce about 0.3 billion tons of CO2 every year in average. Consumption of fossil fuels alone yields about 35 billion tons of CO2 every year [1], so about 100x more. Also, regardless, if you find yourself in a hole, stop digging.

The CO2 current levels in the atmosphere are 0.04%. Levels in the past were well above 1%.
"As a point of reference, pre-industrial CO2 levels were around 280 parts per million (ppm) and today, we stand near 420 ppm.
The most distant period in time for which we have estimated CO2 levels is around the Ordovician period, 500 million years ago. At the time, atmospheric CO2 concentration was at a whopping 3000 to 9000 ppm! The average temperature wasn’t much more than 10 degrees C above today’s, and those of you who have heard of the runaway hothouse Earth scenario may wonder why it didn’t happen then. Major factors were that the Sun was cooler, and the planet’s orbital cycles were different."

They somehow knew that the Sun was cooler then, so that was not a problem. Yeah, right. But now, it would be.
