"There are fifty acres of land here, and if you want to water it completely, you need at least 5,000 tons of water!"

According to the irrigation of paddy fields, an acre of paddy field needs at least 200 tons of water to complete irrigation, but it is flood irrigation, and the desert does not need flood irrigation, and it is impossible to flood irrigation, because the sand on the surface has a strong water seepage ability, they can't retain water, so they just watered one side, so that the water can penetrate into the sand, this sand, not to penetrate too deep, they don't need to be too deep, as long as it can reach about half a meter underground, to ensure that the seedlings of the vine can absorb the water is enough. Pen, fun, pavilion www. biquge。 info

So Lincoln's previous estimate was based on half of the amount of water used in paddy field flood irrigation, so that if you calculate that 100 tons of water are needed per acre, 500 acres of land is almost 5,000 tons.

"So many, that's a difference of more than a hundred times?"

"Well, that's why the Sahara is magical! When the water in the well water is pumped out, the water level does not drop at all, which is very magical. ”

When Lin Quan did this, Lincoln's surprise was not less than Perona's, so at this time he could fully understand Perona's mood.

"Well, well! In that case, doesn't it mean that it is not very difficult for the Sahara Desert to be completely managed? ”

Water is the source of life, if there is no water, then there can be no life, this is a very fresh understanding of human beings, so when NASA sent a Mars rover to land on Mars, the first thing is to find the water source on Mars.

Unfortunately, they didn't seem to have found it, so so far, there is no sign of life on Mars.

In the heart of the Sahara Desert, the situation here is not much stronger than that of Mars, where there is also a great lack of water, and the temperature on the surface is very high, so high that you can bake eggs directly.

The main component of eggs is protein, which is something that exists in the body of every living organism, which is indispensable for living organisms, but this kind of thing is relatively fragile and easy to denature in a high temperature and low temperature environment.

In the middle of the desert heat, the eggs are cooked, but the protein inside is actually denatured.

And such a harsh environment is naturally not suitable for life to survive, but the Sahara still has water, although the water is relatively small, but it is not completely without water, so there are still some more tenacious lives here that survive.

But if there is enough water in the desert, there will be more creatures that can survive.

"It can't be said that although there is water in the ground of the Sahara, because the climate in the desert is too dry, the water is easy to evaporate, and the clouds formed by the evaporated water here will be blown away by the wind, and there will be no rain in the desert area, so if the climate in the desert area is not improved, the development and utilization of these groundwater may not be able to change the current situation of desert expansion."

Although she was poured a basin of cold water, Perona still looked very happy.

"I know, if you want to conquer the desert, it's not such a simple thing, but since you can do this, then other people should be able to do it, just because everyone hasn't done it before, and no one has succeeded, so everyone has no bottom in their hearts, if we expose your deeds now, publicize it, and let more people see this thing is possible, I believe that everyone will definitely treat this matter differently at that time!"

Perona seemed very optimistic, but Lincoln had a question mark in his heart about her optimistic attitude.

He came to Africa for a relatively short time, I don't know what kind of efforts Lin Quan they made before this, but it must not be easy to think about, Africans are generally relatively lazy, to do such a thing, you must get strong help from the government, and African countries are poor countries, so the government's help can be imagined, as for calling on other people in the society to enter this field, it is more realistic, except for some people who specialize in environmental protection will notice this part, who else will be interested here?

After all, the investment here is completely disproportionate to the return, and even if the Sahara is improved, it is not they who will benefit, but the local African countries, and besides, the environmental impact of the Sahara is insignificant to them, because the distance between the two sides is too far, so it is difficult for them to look here.

So for the prospect of desert control, in fact, Lincoln is not very optimistic.

However, the reason why Perona is so sworn is because he knows many people in the United States who are willing to do charity, such as Bill Gates, the world's richest man, Warren Buffett, and the CEO of Google, etc., they all like to do charity.

And compared to what they are currently doing, conquering a desert larger than the mainland of the United States, this kind of thing for the benefit of the whole of humanity, will definitely appeal to them.

Perona believes that as long as she finds a way to reach these rich and enthusiastic giants, it will not be difficult for them to pay.

That night, after the dinner reception, Perona told Lin Quan about her idea.

"Let the rich donate? Is this possible? ”

Lin Quan was very puzzled, as soon as he saw him, he hadn't said a few words, and Perona was very enthusiastic to help him contact sponsorship, and it was a figure like Bill Gates.

Of course, Lin Quan, the name of Bill Gates, has heard of it, saying that when Hu Dada visited the United States, he lived in Bill Gates's home, and I heard that his family built a more magnificent house than the White House, and I don't know if it is true, the White House is where the President of the United States lives, and it is impossible for foreign guests to stay here, and it is also very profitable to be able to live in a place that is not worse or even better than the White House.

"Feasible, of course feasible, Mr. Lin, you may not know, in our country, the inheritance tax is very high, the inheritance tax in the United States is about 18%-50%, this figure is very scary, like Mr. Bill Gates, the shares of Microsoft and other investments he holds in his hands, the total value is estimated to be more than 50 billion US dollars, whether these things are transferred or inherited to their children, they must be accounted for by the US tax department, and then paid according to the total value, which means that Their $50 billion in assets need to pay $25 billion in taxes, and their children only get 25 billion of the remaining assets! ”

Lin Quan was dumbfounded, there is no inheritance tax in Huaxia at present, so he didn't know that there would be such a high tax burden in developed countries, which was really more robbing than robbery!
