Biologist here. I have a simple question in response to your disinformation: What CO2 level is used in commercial greenhouses?
All scientific, controlled experiments with plants demonstrate conclusively that they thrive (faster growth, larger leaves, increased biomass, larger fruits, less need for water, etc.) at higher CO2 levels than what we have today and than we had before the Industrial Revolution. I encourage people who are intellectually curious and honest to look up the scientific papers on the topic and read them for themselves (you don't have to be a biologist or a geologist to understand the experiments, the parameters, or the outcomes).
- humbledrone 8y agoGP said that CO2 was not the _limiting factor_. I took this to mean that something else is often the bottleneck, such as access to nutrient matter. Presumably in a greenhouse, more CO2 can be used because other bottlenecks are reduced.
- cbkeller 8y agoWell said. Yes, if you provide unlimited water, N, P, and light in a greenhouse then of course CO2 becomes limiting, it's the only thing left!
- salty_biscuits 8y agoWell, very high but that's not the point. The poster was saying that it was not the limiting factor in the environment, not in an artificial setting.
