Water scarcity is when there is no water left on earth. Freshwater is a necessity to all living things on earth. Without water living things would cease to exist on our blue planet.
Fresh water is on demand there is over 7.5 billion humans and 8.7 million species on earth imagine how many individual animals there are! Despite all of that demand only 1 percent of clean water accessible to humans and animals on earth. And that one is going to become a zero because of human activity. Pollution is a major issue contributing to water scarcity. The main causes of water pollution include pesticides and fertilizers that leak into water systems from surrounding farms, and human and industrial waste.
Overpopulation causes people to plant more plants and more plants mean more water needed for plants and humans and animals also are in a demand for water to make the situation worse there is only 1 percentage of clean water left on earth!
When all this collect up it becomes a complete disaster! Another reason is pollution. Pollution causes heat in the atmosphere and that causes less rainfall eventually causes a drought which is water scarcity
Many people, in countries and cities that have good rainfall, usually take water for granted. People forget about how precious and pure it is. In some countries, people are queueing for hours to fill up buckets of water from water trucks because their town supply has run out. but in other places, people are standing in the shower singing songs and wasting one hours worth of water, leaving the tap running while brushing their teeth and turning on tapps that use water when they aren’t full. Toilets are getting flushed on the full setting a lot more than they should, clothes are getting washed when they aren’t even dirty and leaks and spills aren’t getting fixed right away.
Overpopulation, and technology are some causes of climate change. Climate change can affect the amount of freshwater accessible on earth. population puts a huge strain on the earth’s resources. Natural environments need to be cut down to make way for cities, towns and housing. More people also means more cars, more pollution and more rubbish. Development and technology has meant more factories and pollution and the creation of appliances, toys, packaging and products that will eventually get thrown away. Pollution and deforestation leads to climate change. The pollution created traps CO2 gases in the atmosphere and causes the earth to heat up. Less trees means more CO2 in the air as trees breathe in CO2 and produce oxygen. One of the negative effects of the earth heating up is more extreme weather patterns, including droughts. A drought is a long period of low or no rainfall. Low rainfall in certain places, especially highly populated places can cause a severe water shortage.
Water scarcity is a huge issue that can have a massive impact on all living things. A clean water shortage means that people slowly become thirsty and then become dehydrated, making them sick or even dead. People might have no choice but to drink polluted and dirty water which can cause diseases, viruses and poisoning. Without clean water, crops can’t grow and produce enough food for people to eat. Animals will soon die, upsetting food chains and natural environments. Life becomes hard when there is a water shortage and natural environments and all living things suffer. Humans need to save water and look after the earth so that there is enough of this limited liquid for everyone that desperately need it.
