Well, the gasses themselves are good for plant life. At least, it wouldn't be "poisonous" to plant life in general. To humans and animals, sure, just look at places in China where the smog is just... horrific. Of course. If you want to say that the rising temperatures as a result of greenhouse gasses is harmful to plant life, then I could agree with that. If you want to say that too high of a concentration of CO2 could cause a reduction of photosynthesis in some plants because it causes their stomata to close up, then sure. But it would also be very beneficial to other plants, such as ferns, which flourish in CO2 concentrations of up to 3000 ppm, ten times that of pre industrial levels. I'm just saying that it's not a cut and dry "CO2 bad, solar power good" argument. There's nuance.Are you implying that pollution from fossil fuels are good for any type of life?
Yes, flora needs CO2. People need water, but look up "water intoxification".
For example, Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants. They also have lead, cadmium, and other toxic (even carcinogenic) chemicals that can't be removed without breaking apart the entire panel. Worse, rainwater can wash many of these toxics out of the fragments of panels over time.
Then there's the vast increase in the use of nitrogen trifluoride, or NF3, in the construction of solar panels over the past 25 years. It's gone up by something like a 1,000%. NF3 itself is a little over 17,000 times more potent than carbon dioxide as a greenhouse gas – meaning that even relatively minor quantities can have major impacts, and it cannot at all be recycled by plants.
All I'm saying is that it's a very nuanced subject that's not nearly so black and white. While fossil fuel energy has its problems, the so-called green energy alternatives also have their own issues that need to be worked out before they can become a viable replacement. I personally think we do need to move away from fossil fuels, not necessarily because I feel they're horribly toxic and going to destroy the planet, but instead because I think there is a cap in how much energy they can produce. As we advance and energy demands become ever more urgent, I feel that fossil fuels are not going to be able to keep up with the demand, especially as we start doing much more in space.
