People need fresh water for survival, personal care, agriculture, industry, and commerce. The 2019 UN World Water Development report noted that about four billion people, representing nearly two-thirds of the world population, experience severe water scarcity during at least one month of the year. With rising demand, the quality and supply of water have diminished Mines also need water for things like equipment maintenance, and for consumption by the mining communities themselves. In total, about 250 litres of freshwater are required per tonne of coal produced One way to meet the freshwater needs of both people and ecosystems is to practice water conservation. Water conservation is the process of using less water to begin with and recycling or reusing as much water as possible. The goal of water conservation is to maintain a freshwater supply that can meet the needs of [ Around half of production requires additional irrigation, and this can add to stresses on local water supply.

  5. g pools, bathtubs, and rivers. This is partly because of the chemistry of the water and how it affects osmosis
  6. As freshwater fish are passively taking in water through the gills in large amounts, they therefore have no need to drink. In salt water fish, the situation is reversed. Now drinking salt water is known to increase dehydration in people, as the salt taken into the stomach actually removes water from the blood stream
  7. Overuse of freshwater in household settings means there is less fresh water for agricultural use (which affects humans on an food scarcity level), but many livestock species rely on freshwater

Whenever humans enter a habitat, they tend to reshape it to fit their own needs, destroying the resources that other animals use, which drives them out.

Climate change and growing demand will likely magnify those extremes. While there is no way to predict exactly what the world's water resources will look like in the future, World Resources Institute has mapped future water-risk scenarios based on the Intergovernmental Panel on Climate Change's projections for climate change. Globally, not only do we rely on less than 1% of the total fresh water to support an estimated 7 billion people worldwide, but the accessible water is unequally distributed.

Main Reasons why we need to conserve water. 1 The reason humans don't have similar kidneys to whales is that humans are bipedal land animals, so carrying around heavier, less-efficient kidneys specialized in filtering saline water, although a life-saving advantage in the extremely rare chance of becoming lost at sea, usually just makes us slower, weaker, and more prone to injury, which, in turn, would make us less likely to survive Summary: Freshwater is essential to the health of our environment and needs to be preserved and protected.
