Water is one of the most basic human needs and is indispensable to almost all economic activities, including agriculture, energy production, industry, and mining. With impacts on health, gender equity, education and livelihood, water management is crucial to sustainable economic development and the alleviation of poverty. Yet water is under unprecedented pressures as growing populations and competing economic sectors demand more of it leaving insufficient water to meet human needs, as well as sustaining the environmental flows that keep our ecosystems healthy. Groundwater reserves are depleted in many places, leaving current and future generations with close to no buffer against increased climate variability.
By 2050 the world will need to feed 9 billion people — 2 billion more than today’s population. This will result in a 50 percent increase in agricultural production and a 15 percent increase in already-strained water withdrawals. Already, the agricultural sector is by far the largest global user of water. Irrigated agriculture accounts for about 70 percent of total freshwater withdrawals worldwide. Yet, water is becoming increasingly scarce as a result of continued population growth, declining groundwater supplies and water quality issues. Climate change will worsen the situation by increasing water stress. Poorer countries contributing least to the problem will be most affected.
As we all know that do due to global warming temperature of the earths atmosphere is rising which results in disasters like melting of ice bergs in the polar regions. This is a big threat because the melting ice will result in the rise of sea level and change in the water temperature which will result in disasters like tsunami and death of marine species. It is found that many portions of the Antarctic ice sheet are nearly 16,400 feet (5,000 meters) thick, including some that extend far below sea level. which is melting at a rapid pace due to the climate change and other man made and natural phenomenons which will eventually lead to the increase in the sea level.
On the other hand micro-plastic contamination has been found in tap water in countries around the world, ranging from 4.8 in USA to 1.9 in Europe including UK. In Europe 72% of the collected water samples from different countries was contaminated with these dangerous micro-particles, most of them are from our fabrics that are washed in the washing machine and few are from the PET bottles. When consumed frequently over a long period of time it affects our health. Even particles of size 2.5 macrons were found in some samples which is 2,500 times bigger than a nanometre.
The main cause of these problem is using plastic and then the improper disposal of the plastic is the biggest problem the world is facing now in terms of water pollution as it is the biggest source of water pollution. As only 3% of the water in the world is fresh water and as pollution level increases the amount of edible water keeps decreasing which will lead to a world wide drought. Rain water is the purest source of water after distilled water because in rain water small amounts of dissolved minerals, as well as particles of dust and dissolved gases can be found in most cases. when it comes to the ocean water which is around 97% of the earths water is also being heavily polluted by the human activities, according to the ocean cleanup organisation, we are now producing nearly 300 million tons of plastic yearly, half of which is for single use. More than 8 million tons of plastic is dumped into our oceans every year.
So inorder to save the planet and preserve water we have to act quickly and with social responsibility we should not pollute our water source which is around 3% of the available water on earth out of which 2% is ice caps which leaves us with only 1% of which the entire world is relied on, Hence its the most precious substance that we should be protecting from contamination.
