DOERING: Next week on the show a plan to place a value on nature and ecosystem services.
BLIMES: So we all love whales. But how much is a whale worth in terms of what it contributes to the economy? Well, in fact, one whale is worth at least $2 million, because the big whales such as sperm whales and filter feeding baleen whales help sequester carbon by hoarding it in their bodies. And they stockpile tons of it, like swimming trees. And if you put it into quantitative terms, a mature tree absorbs up to 22kg of carbon each year, but a single whale in its lifespan stores about 33 tons of carbon dioxide, which means that one whale does the job of 1,500 trees.
DOERING: Valuing nature to encourage conservation, that’s next time on Living on Earth.
