New study finds that whale poop fights global warming

From the article: "Although their numbers have fallen sharply throughout the 20th century, whales continue to play an important role in the marine ecosystem of our fragile planet. This is what was revealed in a new study published in the journal ‘Frontiers in Ecology and the Environment’. Joe Roman , a biologist at the University of Vermont, analyzes the different impacts of these whales and their droppings."

The story is too old to be commented.
