Prior to the setting up of the IWC in 1946, unregulated whaling had depleted a number of whale populations to a significant extent, and several whales species were severely endangered.
Older than dinosaurs and trees, sharks have endured a lot throughout their 450 million years on Earth. They’ve even survived five mass extinctions, including the asteroid that wiped out 75% of ...
