1. How do whales change climate? 2. Explain what rewilding means
3. Find an example where rewilding occurring (you will have to use the internet to search) (1 mark)

1. The way that whales feed, migrate, and dive between the surface and the ocean depths, which is known as the whale pump, circulates essential nutrients throughout the ocean. This in turn supports healthy marine ecosystems and the growth of phytoplankton, which locks in a massive amount of carbon from the atmosphere.
2. Rewilding is restoring an area of land to its natural state, it is used more when reintroducing animals that have been driven out of their habitat.
3. In May, Dutch and Romanian European bison reintroduction programmes were declared successful after several years of efforts. The Dutch project began back in 2007. The bison had been extinct in that region for 20 years. Now, though, both national parks in question are reaping great environmental benefits from the bisons’ grazing.

If you want the answer you need to post the figure above that it's talking about and you
