We all know that the existence of any living organism needs resources, and the most important thing in resources is water resources, after all, "water is the source of life", any living thing is from the ocean at the earliest, at this time people can't help but wonder in the near future, water resources will really be depleted? I don't think it will be for the time being, after all, the earth's water resources are very rich, let's analyze it in detail.
First of all, we have to talk about the level of the universe, our human science and technology continue to progress, and finally successfully enter the universe, that is, we are familiar with "this is a small step for astronauts, but it is a big leap for human beings", and when we enter the universe, we find that the resources of the earth can not support the future development for many years, so we began to explore the second planet, the so-called second planet is to find a second planet in the universe that can be inhabited by human beings. At present, Mars is one of the targets, and it is very similar to Earth in many aspects, such as the distribution of time and the situation of the four seasons.
But there is no water resources found, which directly leads to the current Mars can not be used as a real second planet, it can be seen that the importance of water resources, and the earth can give birth to life The most important nature is rich in seawater resources, we all know that from the universe, the earth is a blue planet, that is, because 70% of the earth's area is the ocean, this great resource, slowly there is the birth of life.
After all, the earth has existed for billions of years, and there is no crisis of water resources withering, and the future will not have an impact in the short term, of course, it cannot be 100% guaranteed, after all, the future is not easy to say, this is the future that we don't know, what we need to do is to continue to develop and make good use of our science and technology to ensure survival.

Water depletion here refers to the depletion of freshwater resources. Since most of the human life needs fresh water, and the reserves of fresh water on the earth are certain, if human beings do not cherish fresh water resources, then fresh water resources will be depleted.
-
At this stage, there is indeed a shortage of water resources, and if human beings do not save water and waste water resources through various behaviors, water resources will be depleted in the near future.
-
As we all know, the existence of any living thing requires resources, and the most important of the resources is water resources. After all, "water is the source of life", and any living thing first came from the ocean. One has to ask, will water resources really run out in the near future?
I don't think it's possible for the time being. After all, the earth is blessed with abundant water resources. Let's analyze it in detail.
-
The amount of water we can use directly or indirectly is very limited, and if we don't cherish the water resources we have now, we will really run out of water one day.
-
If we don't protect the earth's water resources, we will really deplete them。There is a fact that the earth's freshwater resources are decreasing step by step, and groundwater resources are slowly declining in many places. In fact, there is a difference between the two, water and water resources are not completely equal, the world does have a lot of water, after all, seven parts of the sea and three parts of the land.
Water resources: According to the World Meteorological Organization (WMO) and UNESCO's (UNESCO) International Glossary of Hydrology, 2012 definition, water is a water source that is available or likely to be used, in sufficient quantity and of appropriate quality, to meet the specific needs of a place over a period of time. According to the water conservancy science and technology terminology published by the National Committee for the Examination and Approval of Scientific and Technological Terms.

Although water is a renewable resource, the temperature in many areas is particularly high and there is no rain all year round, which leads to drought in the region.
-
Because the local temperature is very high, the environmental pollution is very serious, and the high temperature causes the river to dry up, so it will lead to the depletion of water resources.
-
This is because people are consuming water so much that they are using it faster than they can regenerate.
-
If there was no water on Earth, what kind of creature could you imagine would be able to leave it? Without water, it is natural that these creatures that depend on water to survive will survive, which means that these creatures will eventually disappear. Not to mention that there is no way for those creatures that live in water to survive.
-
Without water, many creatures will be gone.
-
I don't think so, because water can be recycled, and when it evaporates, it becomes rain and falls on the earth.
The Earth's water resources, broadly speaking, refer to the total amount of water in the hydrosphere. >>>More
China is a country with severe drought and water shortage. The total amount of freshwater resources is 2.8 trillion cubic meters, accounting for 6 of the world's water resources, second only to Brazil, Russia and Canada, ranking fourth in the world, but only 2,200 cubic meters per capita, only 1 4 of the world average, 1 5 of the United States, ranking 121st in the world, and one of the 13 countries with the poorest per capita water resources in the world. After deducting the hard-to-use flood runoff and groundwater resources scattered in remote areas, China's actual available freshwater resources are even smaller, only about 1.1 trillion cubic meters, and the per capita water resources are about 900 cubic meters. >>>More
Yes, but you should pay attention to the method and not implement it blindly at will. >>>More
In geography, water resources are usually freshwater resources that can be used directly by human beings.
The source of life - water and water, a very ordinary thing; Water is a precious thing. Water is the origin of our life, and it is also the most basic resource of our life. Although the global water area is larger than the land area, 2 3 of the ocean's undrinkable salt water and 1 3 of the drinkable freshwater. >>>More
