“If we don’t save the oceans, we will not be able to save ourselves. If oceans die, we die. This is my only message.“ Paul Watson
The most important issue for our planet today is to protect and conserve the biodiversity of the oceans. I do not think people realize how intimate our relationship is with the oceans. Not only are they the essence of life and control our climate, but life simply could not exist without healthy oceans. (…) If oceans die, then civilizations collapse and we all die. We cannot live on this planet without the oceans.
At the base of the ocean food chain, there is plankton: this is microscopic food that floats in seawater. This food is eaten by all small fish which are then eaten by larger fish. These fish are then eaten by even bigger fish, and so on until you reach the top of the chain with the shark.
The sea is self-sufficient when it comes to feed its protégés. Nothing gets lost. For example, when animals die, their bodies become larders for the other inhabitants of the sea.
Also, if we take the diagram upside down, it equates to saying that if there are no more sharks to eat large fish, that themselves eat smaller fish, that themselves eat small fish that themselves eat plankton. And then, all these people will disappear.
