A friend of mine says he uses up 2,000 gallons of water a day just from his diet. Is this possible?
Ben, Liverpool
Actually, the total amount of water on the Earth is a huge 326,000,000,000,000,000,000 (326 million trillion) gallons! Did you know that the same water that exists on our planet today has been around for millions of years? All this water is always in motion - evaporating from oceans, travelling through the air, raining on the land and running through rivers, even through our bodies. The supply of fresh water, however, is limited to just 3% of the total amount and there are fears that it won’t be enough to keep the world population alive. After all, the human population has increased in size and the fresh water supply has decreased because of pollution.
Is it true that half of the world's population hasn't got access to clean running water?
Liz, Cardiff
Мапу of us have never bothered to link the food on our plate with the 70% of our planet’s fresh water used in agriculture. For instance, we think that a cup of instant coffee requires the use of just a cup of water. However, it takes 37 gallons of water to produce a teaspoon of coffee beans. And if you add some toast with a slice of cheese along with your coffee, then you can add another 13 gallons to the total amount of water required for your food supply. Add all this up and that’s just 50 gallons of water for a simple breakfast. A day’s supply of food for an average family of four requires 6,800 gallons of water. This amount doesn't even include the amount of water they use when having showers, flushing toilets, doing the washing or washing up!
I've heard that drinking eight glasses of water a day is good for our health. Would it do me any good if I drank double that amount?
Cliff, Bristol
Most of us take it for granted that we can turn on the tap and have a glass of cold water whenever we want. According to the United Nations, however, half of the global population can’t do this. In many places, families rely on the young female members, who are forced to stop school just to collect water for their family. They walk for approximately three hours a day to the nearest swamp or river to collect water that has been sitting in the open and is full of germs. The World Health Organisation (WHO) says that 3.4 million people die yearly from water-related diseases. More specifically, every twenty seconds a child dies from drinking dirty water. Every week. 42,000 people die from diseases caused by unsafe water.
With 72% of the Earth's surface covered in water, why do peoplekeep talking about a water shortage?
Sandy, Exeter
Water is a source of life, but sometimes you can get too much of a good thing. A person who has drunk more water than they need can suffer from water intoxication. People have even died In water-drinking competitions when they consumed too much too quickly because of imbalances created in their body. Other people at risk of water Intoxication are athletes such as marathon runners. The symptoms of water intoxication Include nausea, headaches and vomiting, as well as muscle weakness.
