In spirit of Shark Week, I recently learned that you can adopt a shark via WWF (World Wildlife Fund).
Great white sharks are found in most temperate waters through the world, and are most common around Australia, South Africa and Northern California. Their diet consists of warm-blooded mammals, primarily pinnipeds (seals and sea lions), but also whales, dolphins, fish and squid. Caught for their jaws, teeth, leather and fins, which collect high prices and are in demand worldwide, great white sharks also face the thread of accidental capture in fishing gear, and animals that survival are often killed for their body parts.
You can help the sharks out by adopting one via the adoption kits that they supply. There are different kits you can get that come with different gifts.
