Great White Shark 1 OZ - silver collector coin

..this beautiful collectible coin with the motif of the Great White Shark is a unique gift for you or your loved ones. The Great White Shark is found in coastal waters. It is considered the most dangerous shark to humans and as such has long been systematically exterminated by sailors and fishermen. Its persecution intensified after the release of the film Jaws, so that it now faces an imminent threat of extinction, with the shark population having declined by 70% since 1970. In reality, these sharks do not systematically prey on humans, feeding mainly on fish, mammals and, to a lesser extent, reptiles and birds. Sharks fulfil their role as predators perfectly and perform the same service to nature underwater as lions and tigers do on land. They maintain the balance of other animal and plant populations. Their total or partial extinction could result in an overpopulation of fish feeding on phytoplankton and a consequent lack of plant life, which produces half the atmospheric oxygen produced by photosynthesis. The ocean ecosystem is the most important factor regulating the climate of our planet, so life on Earth depends on life in the ocean.
