The oceans cover more than 70% surface of the Earth and plays a key role in supporting our planet, we rely on it because of food, energy and water.
The ocean containes more than 200.000 discovered species, but the real number is absolutely higher. There are a lot of species who are endangered because of over pullotion or even because of hunting.
Most of the endangered turtles are endangered because humans are harvesting their eggs or the food they need (corals) are destroyed.
Also the dolphin kinds like the Vaquita and Hector’s dolphin are in danger because of fishing.
The most crually hunted marine animal is the Hammerhead shark. The sharks are caught by fishermen, dragged on board and is cut off their fins while they are still breathing. The remaining carcass is thrown into the water and eventually, it bleeds to death.
The largest living mammal on earth is a victim of excessive commercial hunting too.
40% of the ocean is heavily polluted because of the humans. The ocean doesnt just give a living place for more than 200.000 species but gives a livelihood for more than 3 million people. However nowdays 30% of the words fish stocks are overexploited.
So with destroying and polluting the oceans we are not just causing harm to the creatures who live in the water but for our own kind too.
