Space scientists Anna-Lisa Paul, Stephen M. Elardo, and Robert Ferl planted seeds of Arabidopsis thaliana in samples of lunar regolith—the surface material of the Moon—and, serving as a control group, in terrestrial soil. They found that while all the seeds germinated, the roots of the regolith-grown plants were stunted compared with those in the control group. Moreover, unlike the plants in the control group, the regolith-grown plants exhibited red pigmentation, reduced leaf size, and inhibited growth rates— indicators of stress that were corroborated by postharvest molecular analysis.

Why does the EPA not consider CO2 a pollutant even though it is a significant driver of climate change?
People and animals breathe it, and regulating breathing isn't possible.
