Its importance lies in the fact that it is a vital liquid for the proper development and maintenance of life on the planet, it is the basis for all living forms as well as for daily activities, in industry and agriculture.Īll animals and plants need water to survive and without it they would not be able to perform the biological processes necessary for physical fitness and growth. Climate change and the destruction of ecosystems by human irresponsibility has made access to fresh drinking water one of the concerns of most countries in the world, mainly those with the most limited water and economic resources. This is one of the main challenges that humanity will have to face in the coming years. The problem of fresh water scarcity is serious for people, agriculture and industry. Water reserves in swamps rise and fall depending on rainfall. Water scarcity usually occurs in areas of the planet where rainfall is scarce and where there are more episodes of drought.įresh water shortages occur when we have insufficient reserves to guarantee the medium- and short-term supply of water. Water scarcity can be defined as lack of sufficient water, or not having access to safe and healthy water supplies. Canada: has 7% of the world’s renewable fresh water resources and less than 1% of the world’s population.China: has 5-6% of the world’s water reserves but, having the highest population density on the planet, its water distribution is extremely unequal.United States: with 2,480 km3 of water and has plenty of rivers and lakes, although some countries suffer from droughts.Venezuela has approximately 1,320 km3 of water and many rivers end up in the Orinoco, the third largest river in Latin America.Rivers originate in the mountains, but more than 80% of the water is received by rain. ![]() Burma: has 1,080 cubic kilometers of water.The world’s main fresh water reserves are to be found in: The sources from which we can obtain fresh and fresh water are rain, groundwater that can be desalinated and converted into drinking water, ice and ice caps, rivers, lakes, ponds, streams and natural springs. And finally, it is also used as a means of communication. Probably one of the main uses of water is as a source of energy because it is an ideal method for the production of electricity. It is also used in industrial use in factories, workshops, construction and manufacturing industry. The planet’s fresh water can be found in rivers, streams, lakes, pools, groundwater, ice, snow and glaciers. Lotic ecosystem: areas where water has an important movement such as springs and streams or rivers. ![]()
