Now that human beings do not pay attention to the environment and cause global warming, will it really harm human beings?

As we all know, most of the earth is water. Seen from space, we live on a blue planet. The ocean adjoins the land.

There are groups of marine life living freely in it. In countless documentaries and photos, the ocean is strangely inclusive and sacred.

Secrets bring us blue fantasies from the deep sea.

There is a colorful creature in the ocean called coral.

First of all, even if we don't really dive into the water to find out what coral is, we are still in the aquarium.

I have seen their true colors in museums: their bodies are lovely cylindrical, shaped like branches, but softer and swaying with the water waves.

Antenna. It's more like a forest bred on the quiet bottom of the sea.

But they are going to disappear, or this disappearance has lasted for a long time. It's just that it disappeared quietly, so far away from our lives that we never cared too much.

The grim fact is that in the past 30 years, we have lost half of the coral in the world.

In fact, we are no stranger to the word "globalization", but perhaps we have never heard of the word "global coral bleaching".

Think about it carefully, what you saw in the video materials or tourist promotional photos, and even went there in person, are all beautiful.

The fine white coral walking on the amazing white sand beach is the natural scenery accumulated after coral death and bleaching.

According to the documentary, the first large-scale bleaching of corals occurred in the early1980s, and many corals died of bleaching.

Second, in

20 10 years ago 12, we saw the second global coral bleaching. It's only been five years now, and we'll see the third one soon.

Time. It's just that it disappeared quietly, so far away from our lives that we never cared too much.

Come to think of it, you have seen it in video materials or tourist promotional photos, and even been there in person. The beautiful and stunning white coral walking on the white sand beach is the natural scenery accumulated after coral bleaching.

Time. The photographer who filmed in New Caledonia said with great surprise, "It is not surprising that coral groups have very strange behaviors.

Incredibly, corals fluoresce. They produce chemical sunscreens to protect themselves from high temperature. You can't describe it in words,

This is the brightest color I have ever seen, and it is an incredibly beautiful stage of death. Coral seems to say, please look at me and pay attention to me. "Albinism is an irreversible recovery. Coral will suffer first, and it will be more and more difficult for us to see the colorful pictures on the seabed.

Third, the extinction of the entire ecosystem followed. This is a very sad statement, but unfortunately, it is also true.

Coral is the foundation of a huge ecosystem, which can be said to be the trees in the forest. Without coral, a quarter of the world's creatures would be extinct.

Affected.

If the average value is about 25 years, all the oceans on the whole earth will be too hot for coral reefs to survive. Coral died on a large scale for the first time 30 years ago. Imagine that corals will be completely extinct in 30 years. In less than a century, it may witness the extinction of a species again. This is actually a global albinism. The impact of global warming on human beings is not simple, but from all aspects, from the earth's ecology, slowly and silently.

Collapse, seawater and typhoons are all dying out. ?

Like white skeletons and corals in the blue ocean. The next of the four global problems is climate change, which will be closely related to our lives in the coming decades.

Close. Each of us has probably heard of this concept. However, the problem of global climate change is so complicated and confusing.

And it is often presented in front of people with contradictory appearances, so that not many people can really understand this except climate experts.

The problem is that many influential people, including many American politicians, even call global climate change a scam. Now, I

We will explain this problem as clearly as possible through a flow chart of causal chain.

Fourth, climate change seems doomed to the failure of this business. At the same time, the then Dutch Republic Management Committee abolished the monopoly of whaling industry and allowed hundreds of new whalers to join the industry competition. Ironically, it was the crisis caused by climate change that ushered in the golden age of Dutch whaling.

The latest historical research found that many times human society did not collapse in the face of sudden bad weather; On the contrary,

They have successfully met these challenges, some of which have quickly recovered from the crisis caused by climate change, while others have completely avoided the crisis.

Frequent climate fluctuations make human society more adaptable. Our ancestors creatively sought out the countermeasures to get out of the predicament. Holland in the Arctic

The story of the whaling ship is just one example of the success of human beings in coping with climate change with wisdom.

China is one of the countries with a high proportion of elderly people in the world, and there will be more high-temperature heat waves in China in the future.

The elderly are extremely vulnerable to extreme events, and the number of people who get sick or die due to high temperature may increase greatly. Jiang Tong said that this requires China to formulate corresponding climate change policies according to its actual situation, choose a suitable socio-economic development path and strive to achieve sustainable development.

In fact, in Europe in 2003, more than 70,000 people died of heat wave. Among them, France suffered the most, nearly 1.5.

Ten thousand people died of high temperature, most of them were unattended old people. Since the summer of 20 19 in the northern hemisphere, many European countries have been swept by heat waves again. This time, Paris, France set up a special hotline for the elderly and sick people, and government departments also asked hospitals and old-age care institutions to be alert to emergencies.
