CO2 Weakens Soybeans

Elevated atmospheric CO2 may negatively impact the relationship between some plants and insects. A new study from the University of Illinois finds that soybeans exposed to elevated levels of CO2 become more susceptible to attack by Japanese beetles (Popillia japonica), reports the American Society of Plant Biologists. Furthermore, as the beetles consume the weakened soybeans, the insects’ invasive abilities also intensify. . . So how will the naysayers spin this? JULIA WHITTY


Mother Jones was founded as a nonprofit in 1976 because we knew corporations and the wealthy wouldn’t fund the type of hard-hitting journalism we set out to do.

Today, reader support makes up about two-thirds of our budget, allows us to dig deep on stories that matter, and lets us keep our reporting free for everyone. If you value what you get from Mother Jones, please join us with a tax-deductible donation so we can keep on doing the type of journalism that 2018 demands.
