Let me tell you why:
Whales are farmers of the sea. Their flocculent fecal plumes are rich in iron and nitrogen, which fertilize phytoplankton and prochlorococcus (cyanobacteria). Together, the phytoplankton and bacteria provide almost two-thirds of all the oxygen we breathe. Oxygen makes up almost 65 percent of human body weight.
Fossil fuel heat has infused 300 zettajoules of energy into the oceans, half of that has accumulated since 1997. It’s the equivalent energy of detonating one Hiroshima-style bomb every second for 75 straight years. Think about that for just a minute. Hiroshima. Every. Second.
