Answer:
Here's your answer.
Explanation:
Water is the most important natural resource made available by mother earth to the humans. It is essential for existence of life and maintaining ecological balance. Life on earth without water cannot be imagined and history is replete with wars fought between civilizations over water.
Although, earth constitutes 71% of water, only 2.5% of it is fresh water that we use, and we are wasting that too. The fresh water that we use today has probably been around since the beginning of life on earth. The amount of fresh water that the earth holds has remained constant, but the human pollution consuming it has increased manifolds; subsequently, leading to water scarcity. Adequate measure must be taken towards optimal usage of water and methods like rain water harvesting must be implemented in order to ensure future availability of one of the nature’s most valuable resources.
Answer:
Water is the most valuable resource on the Earth and the essential component of the ecosystem because all living beings need it to support their living process. The development of modern industry, agriculture, and technology leads to the world catastrophe, which results in the pollution of water resources as well as their increased consumption. The goals to preserve water resources are determined by the range of necessities. First of all, it is an obligation of the humanity to save water resources for the future generations. Besides, it helps to reduce the level of used energy because water management consumes a huge amount of electricity. Finally, water is a habitat for the different wildlife representatives. Therefore, the world community tries to prevent water resources from their complete disappearing.
The first step to protect water is for people to become more economical. If they control how they use water at least while washing dishes or brushing their teeth, they can save huge amounts of water. There are different water-saving technologies, such as low-flow shower heads and toilets, raw water flushing, automatic faucet, and many other smart devices, which were invented specifically for saving water. Universal metering is considered to be a useful way to reduce the amount of water wasting because it raises people’s understanding and responsibility. Besides, it helps to detect water leakage. In order to reduce the usage of water in agriculture, a pan evaporation is used. The useful feature of this device is that it determines the amount of water needed for irrigation. There are also crop correction factors for the delivery of water, such as flood irrigation, overhead irrigation, and drip irrigation.
Apart from water disappearing, the problem of water pollution takes place in the modern world nowadays. Big water areas become insufficient for using because the level of their pollution is unacceptably high. It makes water resources impossible for people to consume, and fishes and plants to live in. To prevent pollution, large plants and factories have to control their emissions and assume measures to provide them with the appropriate equipment, which helps to reduce the emissions.
Consequently, the problem of water pollution and conservation takes a significant place among other environmental issues due to its severity and negative consequences for the mankind and planet in general. There are different ways to prevent water pollution and preserve it by means of wise using of water resources as well as the invention of special technologies. Water conservation is an important mission for the global community to deal with to keep the planet safe for living.
