"Dicamba is particularly bad because it travels far compared to other pesticides. With little to no control of where the pesticide goes, it can have lasting effects on our crops. Public health is also at risk. With the chemicals spreading onto neighboring farms, we have no assurance that the pesticide is not also spreading to homes, schools and playgrounds as well."
"It's a hidden issue,” Ebi said. “The fact that my bread doesn't have the micronutrients it did 20 years ago―how would you know?"
As Ebi sees it, the CO2-nutrition link has been slow to break through, much as it took the academic community a long time to start seriously looking at the intersection of climate and human health in general. “This is before the change,” she said. “This is what it looks like before the change."
"We've known for a while that climate change is going to mess with agriculture in a lot of ways," says Ricketts. It will move the areas where both coffee and pollinators live – but not necessarily in the same way.
"These are all individual species that happened to co-occur now," Ricketts says, but they each have different tolerances to heat. For example, a bee that is at the very edge of its heat tolerance won't follow coffee into warmer areas."
