Reservoirs and hydropower are often thought of as climate friendly, but new research suggests that we may have underestimated the amount of methane they produce. The methane—which is 35 times as potent a greenhouse gas as CO2 over the span of a century—is produced by bacteria eating nutrient-rich agricultural runoff.
"is produced by bacteria eating nutrient-rich agricultural runoff."
So industrial farming more than hydroelectric power really. It always seems to come back to industrial farming and industrial animal agriculture. We need Soylent green, and we need it now!
