Human’s activities and Water cycle
“Water is the source of life”------The president of IWRA Li jun.
As we know, water is one of the most important energy in human's daily life, We can't life without water. In daily life, people and water have a special relationship. People use water for many of the activities.
Water cycle is to point to different places on the water on the earth, by absorbing the sun's energy, change state to another place on the earth.The ground water by solar evaporation become water vapor in the air. The water in the state of the earth including solid, liquid and gas. Most of the water and earth exists in the atmosphere, ground, underground, lakes, rivers and oceans. Water will pass some physical effects, such as: evaporation, precipitation, infiltration, surface flow and ground flow and so on, from one place to another place. Natural factors mainly include meteorological conditions (atmospheric circulation, wind direction, wind speed, temperature, humidity, etc.) and geographical conditions (topography, geology, soil, vegetation, etc.). Human factors have direct or indirect effects on the water cycle.
According to WWF（ World Wide Fund for Nature or World Wildlife Fund ） statistics，with water about 8 billion of the global population year，about 4.13 TCM，Global water resources are being gradual reduced .Global water resources are being gradually reduced . So, There were many serious problems. They cause many countries are lack of water, the citizens in those country even don’t have enough water to drink, they live in a dry and poor place. Therefore, Water cycle is a pretty good way to transfer the water energy to those country.
Water cycle has its good things for the world and its bad things for the world.The water cycle is the world's most active energy exchange and one of the mass transfer process, and it balance the global water，makes global water resources is in a state of constantly updated. Water cycle is benefit to Water transfer. It is water cycle’s advantage. However, there are many disadvantages about Water cycle. One of the most terrible disadvantage is Water cycle will cause the Acid rain, the rain of the pH value is less than 5.6 and one of the most Corrosive strong rain，the plants which were caught by acid rain will be corrosion lead to death. And also, Acid rain has adverse influence on the soil，it cause the soil which was caught by Acid rain is land with heavy metals. If the vegetables in our daily life were planted in Acid soil, it can't be eat. Otherwise consequence is unimaginable. Another disadvantage is water cycle give serious harm to the natural ecosystem.the main hazard is dirt deposition, it Caused the air pollution and made the haze and some poisonous bacteria into the air . If we breath these pollution air, it bad for our health. These disadvantages cause a lot of serious problems for water ecosystem and human’s daily life.
Therefore, human should pay attention to save the water and try best to protect the environment, and reduce the amount of pollution to the ecological environment. There are two solution to solve the problem. One is making a law about water cycle protecting. Another one is actively promote the water conservation measures.Perfect the relevant laws and regulations. If a violation of the law should adopt the corresponding punishment. According to <<China water resources protection law>> stipulated in article 21: enterprises and institutions shall be forbidden to no drainage license or in violation of the provisions of the discharge permit to the water discharge of waste water and sewage prescribed in the preceding paragraph.
According to <<China water resources protection law>> stipulated in article 30:Forbidden to discharge or dump radioactive solid wastes into any water body or waste water containing any high-or medium-level radioactive substances. They are benefit to protecting the water ecosystem and save the water energy.
All in all, water cycle has its good things for the world and also has its bad things for the world. We can't change the variation regularity of water cycle. One thing we can do is try our best to protect the water ecosystem and never damage the water ecosystem and never waste the water energy.Let us work together to protect water resources and let the water cycle with its positive effects for the benefit of mankind!
