Water is the source of life, water saving cannot be ignored!

Although water circulates in nature, human water consumption is much higher than the water that can be used by humans. Saving water has become something that each of us should do

.

I think that both used water and polluted water can be reused. For example, the water used for washing vegetables and clothes can be used to flush toilets, and polluted water can be used wherever possible. This not only reduces water bills, but also achieves the purpose of saving water. Urban sewage should be reused in public facilities and residences for flushing toilets, watering green spaces, landscape water, watering roads, etc. In this way, the recycling effect of sewage will be greatly improved!

Did you know? 70.9% of the earth is water, but 97.47% of this water is salt water. Most of the salt water is ocean water and cannot be drank, because there are 39G salt substances in 1KG of ocean water; and 2.53% of this water is fresh water, and fresh water Most of them are glacier water and deep groundwater. These two types of water account for 99% of freshwater. The water available for us humans only accounts for 0.3% of freshwater. Our water resources are very small. Our country is a country that is short of water. Therefore, we must save water and protect water resources.

The use of water resources is ubiquitous in life. The sewage discharged from factories can also be recycled after purification. However, there is also a price to pay, such as the cost of purification, which in turn requires consumption. resource.

Rain is something that every one of us has seen. Of course, it’s hard to say whether you have ever thought of using rainwater. Scientists all believe that rainwater is actually a rare wealth. It is also a water resource and is quite precious. However, from a national perspective, the collection and utilization rate of rainwater in our country is still very low. We should treat rainwater with a scientific development mindset. , use scientific methods to treat rainwater, let the rainwater stay, be scientifically and recycledly used by us, and then send it scientifically into the ground or into rivers and lakes. Isn’t this a way to make full use of water resources?

In fact, most people know the preciousness of water, but they also choose to forget it. How many people don’t know how to save water? How many people waste water? I'm afraid there are many. This is related to publicity. I think TV should broadcast more issues about resource utilization. Government publicity is also very important. And the flowers of the motherland in the new era should develop good habits of saving water from an early age. You know, we humans cannot live without water, and the entire earth cannot live without water!

Moreover, saving water has many benefits. It is not only conducive to alleviating the contradiction between supply and demand of water resources and reducing the pressure of urban development on the environment. It is also conducive to continuing investment in the construction of water supply and sewage treatment facilities and reducing the cost of water supply and sewage treatment. Facility operating costs. From a strategic perspective, water conservation definitely benefits everything but harms it!

Saving water does not rely on the efforts of one person, but the efforts of thousands of people. But no matter what method is used, we should act immediately and turn ideas into actions. You must know that water is decreasing day by day, it is urgent to save water!

Future Energy

Now, every country needs energy. Look, some countries are quarreling over energy, and some countries are ready for war over energy and want to use force to plunder energy (such as the war between Iraq and Kuwait, and the maritime territorial dispute between Indonesia and Malaysia). It can be seen how important energy is, because most of the electricity we use now is developed and utilized using coal as energy; most of the cars running on the streets are powered by gasoline or diesel, and gasoline and diesel are mined underground. It is extracted from petroleum; most cooking at home uses gas and natural gas.

It is said that the extraction and use of oil, coal, and natural gas will pollute the environment to varying degrees!

So, what if one day all the oil, coal, and natural gas underground are exhausted? Perhaps, in less than 100 years, the earth's underground energy sources will be exhausted.

By then, because there is no electricity, the TV cannot be turned on, the air conditioner cannot be started, the computer is useless, and even the lights cannot be turned on at night; because there are no oil and coal resources, airplanes, trains, ships, and cars cannot be operated. Moved. As a result, we can only go to school by carriage or bicycle, and the streets and homes are dark at night. When doing homework at home at night, we can only burn firewood for lighting. Wow! Is that too scary? !

It is said that there is another energy source that uses water to generate electricity, but developing hydropower requires intercepting rivers and will affect the ecological balance of the earth!

I don’t want to see quarrels and wars in the world. I want the world to be filled with joy and peace. So I imagine how great it would be if every household had a "micro-energy generator". This energy device does not require us to destroy underground resources. It can absorb and store all natural energy sources such as solar energy and wind energy at any time (if it is placed on the beach, it can also absorb and store the kinetic energy generated by tides at any time

... ...), when energy is needed, it can be released for everyone to use anytime and anywhere. If a large amount of energy power is needed (such as airplanes, trains, ships), many "micro energy generators" can be combined with each other to provide energy. In this way, with this "micro energy device", every country in the world may no longer quarrel or start wars; and it will certainly not cause environmental pollution or destroy the ecological balance; at the same time , can beautify our cities, because we do not need those unsightly telephone poles, wire towers and cables wrapped around them like spider webs on the streets; also, this kind of "micro energy generator" does not require high-voltage transformation. Electricity can completely eliminate the health damage caused to humans by the radiation produced by electromagnetic waves.

Perhaps in the near future, "miniature energy devices" will appear, bringing peace, health and happiness to mankind!
