Reducing foods environmental impacts through producers and consumers


Food's environmental impacts are created by millions of diverse producers. To identify solutions that are effective under this heterogeneity, we consolidated data covering five environmental indicators; 38,700 farms; and 1600 processors, packaging types, and retailers. Impact can vary 50-fold among producers of the same product, creating substantial mitigation opportunities. However, mitigation is complicated by trade-offs, multiple ways for producers to achieve low impacts, and interactions throughout the supply chain. Producers have limits on how far they can reduce impacts.

What nobody really knows is not whether climate change is real--there's substantive consensus behind that--but whether environmental regulations are hampering American economic competitiveness. A 2014 policy brief published by the London School of Economics suggests that any negative effects that environmental regulations have on job growth are small, and job relocations are "more likely to occur within countries, where relocation barriers are low, than across borders."

The great apes' primary threat is the rapid deforestation of their habitats. With the global demand for palm oil growing exponentially, forests are being slashed and burned to make way for plantations. Without their home, orangutans have a hard time bouncing back, as they only reproduce every six to eight years.
