Look for two independent certifications that guarantee your coffee was grown under trees, not with chemicals.

Review your brew: The right coffee can keep you—and the planet—a lot healthier.

RODALE NEWS, EMMAUS, PA—Global warming could put a lid on your morning coffee habit. A new study published in the online journal PLoS One has found that rising temperatures are leading to the proliferation of a devastating pest, the coffee borer beetle, which digs into coffee cherries and lays eggs there, killing the plant. The researchers found that each one-degree-Celsius rise in temperature is accompanied by an 8.5 percent increase in the number of bugs on coffee farms.

Interestingly, the study also found that coffee grown with the planet in mind—i.e., without cutting down rainforest vegetation and dousing the crop with chemicals—was less susceptible to infestations. The coffee borer beetle attacks full-sun coffee plantations much more so than shade-grown coffee plantations, where coffee is grown under shade canopies. Those shade canopies provide habitats for birds, which eat the coffee borer beetle and serve as natural pest controllers.
