Sharks

3 reasons to love sharks

Sharks are known as greedy and bloodthirsty gluttones, but you better thank them. These are three reasons.

1. Thanks to sharks, your wounds heal faster

Sharks have a fantastic immune system.

Their blood, like that of humans, contains antibodies, but sharks are smaller and very stable.

That means that they efficiently bind to antigens from cancer cells, for example, if scientists know how to adjust them.

The antibodies also ensure that wounds in sharks heal quickly, and researchers try to imitate that property. They hope that we can take advantage of it.

Wounds not only heal faster with sharks, they can also clean their wounds.

Proteins in the skin of a shark seem to fight bacteria in a very efficient way, keeping wounds free of infections.

2. Sharks protect coral reefs

Sharks form an important part of the food chains that maintain the coral reefs.

Research shows that there are many more sea bass in some important coral reefs when the sharks disappear.

Sea bass eat parrotfish, which are essential for the coral because they remove algae from it.

When the sharks disappear, the parrotfish and the coral reefs die out.

3. Sharks are good for the climate

If the sharks disappear, coral reefs - as explained above - will die. This is harmful for the algae that live in symbiosis with the corals, and therefore for the entire ecosystem.

All seas and oceans will suffer the consequences, just like our climate.

Algae in the seas produce around 80 percent of the oxygen that we so badly need.

Moreover, they extract a large part of the carbon dioxide that we emit from the air, which contributes to a stable temperature.

When Anatoli Boegorski now looks in the mirror, he sees two different people. One side of his face bears the signs of the 75 years he has lived, but the other side is frozen in time and does not seem to have aged a day since July 13, 1978. On this fateful summer day in 1978, the Russian scientist was the victim of a unique accident in world history.
