During the 19th Century, whales were hunted mercilessly and almost to extinction for their whale oil which powered oil lamps and industrial machinery. Now whales are starting to be valued again, but this time in a positive way. A group of researchers, entrepreneurs and economists is betting that putting a price on whales again – this time to facilitate financial investment in their carbon-storing services – will help to both offset carbon emissions and protect the animals. The idea of pricing forests, coastal seagrass and other natural resources that absorb carbon and help fight the climate crisis – so that companies can invest in them to offset emissions – is gaining popularity and is expected to grow exponentially in the coming years.
