speech on water the essence of life

Answer:
Explanation:
water enables life on Earth. Human beings can survive three weeks without food, but only three days without water. According to H.H. Mitchell, water forms 83% of the lungs, 79% of muscles and kidneys, 73% of the brain and the heart, 64% of the skin and 31% of even the bones. Access to clean water makes life possible. It is little surprise that the United Nations (UN) has declared that ensuring “availability and sustainable management of water and sanitation for all” is one of the Sustainable Development Goals (SDG).
Today, we are living in a world where clean water is increasingly scarce. In 2009, the World Health Organization (WHO) pointed out that more than 3.4 million people die every year because of water-related diseases, making it the leading cause of disease and death around the world. Of the 3.4 million, most are children who die because of pathogens in the water. This occurs because a lack of sanitation and sewage systems ensures that untreated human and animal fecal matter ends up in the water. The WHO estimates that 2.4 billion people lack access to sanitation and 663 million to clean drinking water.
Many emerging economies have achieved extraordinary economic growth at the cost of their environment, with water pollution reaching spectacular levels. China, home to more than 1.3 billion people, is a classic example. The Chinese Environment Ministry has admitted that about 60% of underground water and a third of surface water in China is unfit for human contact. India, with its fast-growing population of over 1.25 billion people, is in a worse state than China. Almost 70% of its surface water and a growing percentage of its underground reserves are “contaminated by biological, toxic, organic and inorganic pollutants.” Apart from communicable diseases, water is now causing chronic ones. Heavy metals are making their way via water into the soil and from there into the country’s food supply. What people eat on a daily basis is damaging their health and wellbeing.
Another worrying trend is that human beings are increasingly using larger quantities of water. The UN points out that “water use has been growing at more than twice the rate of population increase in the last century.” In China, increasing desertification is setting off alarm bells as the Gobi desert “gobbles up 3,600 square kilometers of grassland each year.” The World Bank has warned that, if current trends continue, 60% of India’s aquifers will be in a critical condition in 20 years. Already, India relies on its aquifers and pumps out “an estimated 230 cubic kilometers of groundwater per year — over a quarter of the global total.”
The World Bank has painted a grim picture for the arid Middle East and North Africa (MENA) region and predicts that “per capita water availability will fall by half by 2050, with serious consequences for the region’s already stressed aquifers and natural hydrological systems.” Even California, with its lush lawns and backyard swimming pools, is facing a severe drought and imposed its first mandatory restriction on water usage in April 2015.
