When carbon dioxide levels rise, soybean plants benefit by growing more! A study found that with double the usual carbon dioxide, soybeans increase photosynthesis, biomass (plant matter), and seed yield by 32%. Data suggests that since 1800, soybean yields might have gone up by 13% because of rising carbon dioxide levels. This increase in plant growth due to more carbon dioxide may help offset carbon emissions from deforestation. The study also shows that other plants, like trees, respond similarly to increased carbon dioxide by growing more. So basically, more carbon dioxide in the air can actually help plants grow better and produce more seeds!
