Having a bus can waste a lot of water, so it's Better to have a quick shower. Also remember to turn off the tap when you brush your teeth. That way you can save over a hundred leaders of water in a week.
We all need water. But only two point five percent of the water that exists on earth. He's fresh water that's not very much knowing where fresh water is and how we manage IT can help us provide a solution to one of our most pressing problems, making sure there is enough water to sustain all living things on the planet. So where is this water and how much is there are? Of IT, about seventy percent is in the form of ice. Thirty percent is ground water. And lastly, only one point two percent services water, namely rivers, lakes, ground moisture, permafrost and water present in the atmosphere. It's a common perception that fresh water exits only in rivers and lakes, but most liquid fresh water is actually hidden underground and can be found in most unexpecting places. So who uses this water and how is IT managed? Domestic accounts for eleven percent of total fresh water consumption, industry nineteen percent, and agriculture seventy percent. Apart from Fisheries and agriculture, farmers grow and breathe the vast majority of the food we eat using the great apart of the planet's fresh water resources. Two terms have been coined to, referred to the water used by agriculture, blue water, angry water. When rainfalls over a field, some of that water get stored in the upper oil as moisture. This is called Green water and accounts for most of the water . used in agriculture. Blue water makes up all surface water, such as rivers, lakes. There's well as ground water. These resources are exploited for irrigation when droughts occur and rainfall is scared s often, these irrigation techniques are not efficient and can easily deplete aquifers. Rivers and lakes industries, the second largest water user, mainly due to the fact that ninety percent all electricity generation is water intensive. The current water use such an agriculture and industry is not sustainable, but we are also personally responsible for the global water footprint. We know about the water usage of a typical household in developed countries. Each person uses up to three hundred leaders of water every day, washing the dishes, thirty liters of water per day, taking a shower up to eighty leaders of water per day, flushing a toilet, sixty five leaders per day. During the laundry, up to one hundred leaders follow. But we consume far more water than we might realize. In fact, we eat consumers as much as five thousand leaders of water every day. About ninety percent of our water consumption is invisible to ah this is what we call . virtual water. Water is essential for the production of just about everything from goods to electricity to manufactured products. But mostly for the food we eat. Meet Daisy easy needs eight thousand, five hundred kilograms of wheat, corn, grain and ruffle to reach maturity. Over a period of three years, IT takes three million, sixty thousand leaders of water to grow her food. We also need to take into account the twenty four thousand leaders SHE drinks during the three years, not to mention the seven thousand liters used to service the farmhouse transportation . and for the process of slaughter. In total, we've in need almost three point one million leaders of water to produce two hundred kilos of bones beef, that is more than five thousand liters for a modest three hundred gram stake. Obvious not everyone on the planet consumes the same amount of fresh water each day. In fact, people living in developed countries are a privileged minority think that three billion people still lack access to safe drinking water. That's almost half the earth's population. IT would make AQ of people long enough to stretch to the moon and back again. All of us, and people in developed countries in particular, must be aware how our world consumption affects the planet and all living things in IT. In the era of technology and information, ignorance about our water footprint is unacceptable. Globalization, who shrunk the world, we are all highly interconnected, and our consumption patterns have an impact much beyond our local communities.
Section three, expressing and communicating ideas, speaking, talking about different ways of using water. Page seventy five. talk in groups about how we use water in different places. Look at the example and use the list below to help you. Water is an important part of our lives. We use IT for so many things at home. You're right.

Tapescript
Good evening and welcome to this week’s episode of The Natural World. I’m Rebecca, and tonight we’ll be talking about water. About 70% of the Earth’s surface is covered by water, but 97% of it is salt water, which is not drinkable. Only about 3% of the water on Earth is fresh water, and most of that is locked up in ice. So, only about half a percent of Earth’s water is usable for drinking. Clean and safe drinking water is hard to find in many places.

Water is essential because most of the human body is made of water — around 60% in an average adult. Some parts of the body contain even more, like the brain, which is about 75% water. While humans can survive for weeks without food, we can only live a few days without water. We need around 2 to 3 litres of water per day, and athletes usually need more. In hot weather, people also require more water.
