The terrible things that would happen if all the coral reefs died off

We are currently facing the most unusual coral bleaching in history, but what will happen if all the coral reefs disappear? We lose 50% of the world's corals and we may lose more. If the world loses all coral reefs, the result will be bad. This is a video transcript.

In the past 30 years, this planet has lost 50% of its coral. If it remains, the result will be bad.

Marine life is the greatest loss. Less than 1% of the ocean floor is covered with coral reefs. However, they provide an important ecosystem for a quarter of marine life.

One of the creatures - the sea son is actually an important component of certain anticancer compounds

In fact, we predict the possibility of finding new drugs from coral reef ecosystems 300 to 400 times higher than on land ecosystems. But for the first time after they survived the next century

In addition to revolutionary medicine, more than 500 million people rely on these coral reefs for food and work.

Almost one-fifth of the world's proteins come from seafood and people eat an average of 50 pounds per year.

The US fishery supports just 5 million jobs and nearly a quarter of the US meat and poultry industry

Without coral reefs, billions of marine creatures will be affected, millions of people will lose their most important food sources and the economy will suffer seriously.

Coral reefs attract visitors to more than 100 countries and regions around the world. These tourists spend billions of dollars to jump into underwater landscapes

Without these appeals, the economist estimated that coastal tourism will decline by more than 9%, which is about $ 36 billion.

These coral reefs also protect coastal lines that rely on tourists. They offset 97% of the strength of the waves and function as a natural barrier while protecting over 200 million people. Construction of the revetment for the same protective measures requires 2.5 million dollars per mile.

Today, however, humans endanger all of these things. Rising seawater temperatures and pollution press the coral and corals can destroy coral ecosystems in just a few months.

One of the main reasons that coral reefs should not be protected is cost. Protecting coral reefs and providing a more healthy environment for coral reefs can be very expensive. Many things happen to provide a healthy environment for coral reefs. First, greenhouse gases, especially carbon dioxide, need to be drastically reduced in the atmosphere and in the water. To do that, we need to make many changes, such as very expensive alternative fuels. Second, the coral seawater temperature must return to its normal range again. Finally, pollution and waste that is currently being dumped into the water must be handled differently than corals. Completing these three things can be very expensive. In addition to cost it is almost impossible to stop everything that affects coral reefs.

As part of the global industry, coral reefs have made a great contribution to the world economy. In fact, some countries, like the Caribbean countries, receive revenue primarily from activities centered on coral reefs. Unfortunately, the number of coral reefs has declined recently at an amazing rate. This unprecedented reduction, such as irresponsible destructive fishing methods, contamination from neighboring areas, mining coral mining, excessive erosion from coastal area artifacts, poses a serious threat to coral reef function I am in

Coral reefs around the world are very bad shape. Most of coral reef damage is related to the overfishing of herbivorous fish such as parrots and gladiolus so the algae overwhelm the coral. Other problems include nutrient contamination, global warming, acidification and so on. Coral is also used for building materials. Global warming leads to coral hunger and death, where symbiotic photosynthetic algae living in coral polyps lead to "coral fading" abandoning the host. In the past few years, serious continuous bleaching destroyed two-thirds of Australia's famous Great Barrier Reef
