On the periphery of Lake Novo Islands, the bow of a large freighter.

Gu Kaiwen casually asked the captain Xiong Dabao about the cause of death on the coral reef in the lake.

Xiong Dabao responded, "What else can there be, global warming!"

"Last year, coral reefs around the world bleached because of global warming. Xiong Dabao continued, "Nine out of ten of the coral reefs in this lake are due to global warming, which has caused bleaching death. Xiong Dabao said his guess.

"Coral reefs around the world are dying on a large scale?" Gu Kaiwen was stunned for a moment.

Xiong Dabao nodded affirmatively, "Yes, we have a captain's exchange group, and we also said this thing before, all over the world, coral reefs are dying in large areas. Australia's Great Barrier Reef is an example of this, where coral reefs are also dying extensively. ”

Corals are very sensitive to temperature.

The best temperature for coral growth is 18 to 20 degrees Celsius, and either too high or too low a temperature can cause coral death.

For example, at 16 to 17 degrees Celsius, the polyps will stop eating, and at 13 degrees Celsius they will die, and above 22 degrees Celsius, the zooxanthellae that live in symbiosis with the polyps will escape, and the zooxanthellae will escape and cause the corals to have no nutrient supply, and eventually bleaching and dying.

Now the lakes of the Novo Islands have a coral bleaching problem, which is naturally due to the high temperature, which leads to the problem of zooxanthellae escaping.

Gu Kaiwen sighed, it's the problem of global warming again!

This is a serious problem!

But to solve this problem, it is also a little too difficult.

Nearly three o'clock in the afternoon, the seaplane returned, and Zhang Weihai arrived in the Novo Islands.

Zhang Weihai and Gu Kaiwen exchanged pleasantries for a few minutes, and then went directly to work, Gu Kaiwen basically didn't understand this matter, he was also happy to be idle, he rode a motorboat to take pictures, and chatted with Yao Feifei by the way.

'Fei Fei, do you regret it now?' Gu Kaiwen was riding a motorboat inside the lake, and it was less dangerous to ride a motorboat in the lake, but Gu Kaiwen still spared his life.

Yao Feifei replied to the message, 'Hey, so angry!'

'Hehe, the scenery here is very good, and you can eat original seafood every day. Gu Kaiwen sent a message.

Last night and at noon today, Gu Kaiwen ate seafood caught in the sea.

I have to say that the seafood caught in the sea is indeed better than the seafood eaten inland.

'When I'm on vacation, senior brother, if you go to the Novo Islands again, I'll go too!' Yao Feifei made a 'clenched fist' emoji, she did have a little regret now.

However, the final exam is approaching, and Yao Feifei has no choice.

While Gu Kaiwen and Yao Feifei were chatting, Zhang Weihai, with the help of Sun Fei, was quickly inspecting the situation of the lake.

"Feizai, are you sure this Boss Gu can come up with more than 2 billion funds?" Zhang Weihai asked Sun Fei while testing the information of the lake.

Sun Fei responded affirmatively, "I'm sure, I promise, I'm sure." Mr. Zhang, you have asked this question many times, Boss Gu is really rich, and the key is that he is willing to invest in natural environmental protection projects. So you put a hundred and twenty hearts, this lake's coral reef restoration project, he will not fool 100%. ”

Zhang Weihai breathed a sigh of relief, "That's good! We have encountered trouble in the Shanan Islands, but we are short of scientific research funds, so we just borrowed this project to verify some things." ”

Sun Fei reminded on the side, "Teacher Zhang, if you want to do verification, I won't care about you, but you must do the corresponding things well." That big boss Gu is really willing to spend money, but his money has to be spent in practice, understand?"

"You care about him so much?" Zhang Weihai asked rhetorically.

"It's not that I care about him, it's that he's already at a certain level. By the way, he has a very good relationship with the old Chen family, and there were originally some voices against him, but they were all suppressed by the old Chen family. So, you understand, right?" Sun Fei revealed some confidential information.

Even Gu Kaiwen himself didn't know about these confidential information.

Zhang Weihai responded clearly, "Well, I understand!"

At five o'clock in the evening, Novo Islands time, Gu Kaiwen and his party were preparing a seafood feast on the deck of the cargo ship.

The time in the Novo Islands is three hours faster than that of Xia Guo, and now the time in Xia Guo is more than two o'clock, Gu Kaiwen casually took a few pictures of seafood and sent them to Yao Feifei.

Sun Fei was dripping blood from the side!

Gu Kaiwen always uses the satellite communication network to send the original map, which really makes Sun Fei feel distressed, but thinking about the big business in the Novo Islands, what else can Sun Fei do?

Of course, it is to make Boss Gu rich and capricious!

After Gu Kaiwen sent Yao Feifei the original picture of the seafood, he looked at Zhang Weihai and asked, "Expert Zhang, how is the situation in the lake?"

Zhang Weihai responded, "At present, a basic investigation has been done, mainly to test the sea temperature, pH value, and a rough analysis of chemical agents, as well as man-made damage inspection. ”

Gu Kaiwen didn't speak, he waited for Zhang Weihai to continue to elaborate.

Zhang Weihai recounted, "There is no problem with the sea temperature for the time being, and I have put 30 temperature detectors, evenly distributed in the lake, and the temperature is 19 degrees, which is very suitable for the growth of corals." However, the surface sea surface temperature is a little higher, but it is a minor problem. ”

"There is no problem with the pH value, the acidity is moderate, and it is still suitable for the growth of polyps. Zhang Weihai continued, "After a rough inspection, no chemical contamination was found for the time being, and no traces of man-made destruction were found. ”

After listening to this, Gu Kaiwen complained, "In that case, why are the coral reefs in the lake bleaching?"

Zhang Weihai responded, "It's not certain for the time being, I'll set up a studio on the ship at night, and then start a detailed test of the polyps tomorrow." ”

"Well, no problem. Gu Kaiwen responded.

After responding, Gu Kaiwen added, "By the way, according to the current conditions of the lake, we can restore the coral reefs of the lake, right?"

Zhang Weihai hesitated for a few seconds before responding, "If the polyps in the lake are tested and no special cause is found, the lake will definitely recover." ”

"That's good!" Gu Kaiwen breathed a sigh of relief.

Ten o'clock in the morning the next day.

Gu Kaiwen was exercising on the deck of the freighter, even in the vast sea, Gu Kaiwen insisted on exercising, and did not mean to let himself go.

When Gu Kaiwen was exercising, Zhang Weihai took the initiative to find Gu Kaiwen.

"Mr. Gu, I have determined the cause of the death of the polyp. Zhang Weihai said to Gu Kaiwen.

Gu Kaiwen responded, "It should be global warming, which then causes zooxanthellae to escape, and eventually leads to the death of polyps, right?"

Zhang Weihai was stunned for a moment, Gu Kaiwen still understands coral?

Sun Fei said the reason on the side, which made Zhang Weihai smile bitterly, he thought that Gu Kaiwen understood coral!
