Read the passage from "For More Wonder, Rewild the World" by George Monbiot.

Well, it now turns out that the whales are crucial to sustaining that entire ecosystem, and one of the reasons for this is that they often feed at depth and then they come up to the surface and produce what biologists politely call large fecal plumes, huge explosions of poop right across the surface waters, up in the photic zone, where there's enough light to allow photosynthesis to take place, and those great plumes of fertilizer stimulate the growth of phytoplankton, the plant plankton at the bottom of the food chain, which stimulate the growth of zooplankton, which feed the fish and the krill and all the rest of it. The other thing that whales do is that, as they're plunging up and down through the water column, they're kicking the phytoplankton back up towards the surface where it can continue to survive and reproduce. And interestingly, well, we know that plant plankton in the oceans absorb carbon from the atmosphere -- the more plant plankton there are, the more carbon they absorb -- and eventually they filter down into the abyss and remove that carbon from the atmospheric system.
