Margarine has a significantly lower environmental impact than butter in four important areas: global warming potential (i.e., carbon footprint), eutrophication potential, acidification potential, and land impact
Poultry farms generate up to 938 megatons of bird litter each year, but now researchers have identified an efficient way to repurpose that waste as fuel.
What if the world phased out meat consumption over 15 years? The numbers are stunning—and instructive.
Such a bold transition would cut anthropogenic emissions by 68% by century-end, and get us more than halfway to achieving the goals of the Paris Climate Agreement.
Widespread installation of solar panels would have cascading effects on the climate
For all its philosophical troubles, wilderness—big, contiguous places with minimal human footprints—is still enormously important to prevent extinctions.

New study finds that birds caught on California farms with nearby wildlands had less problem bacteria than those at more manicured farms.
Few members of the animal kingdom are quite so maligned as sharks. And yet: might sharks have friends?
Researchers suggest the best ways to reduce the societal impact of aviation's climate and pollution emissions
When computer climate models run farther into the future, they underestimate likely warming by a factor of two. Therefore, they underestimate eventual sea level rise as well.
