Global challenges in terms of water availability and water use are highlighted. Focus is placed on the availability, distribution and use of freshwater resources on a global scale. 1.1 Introduction. Water is one of the most widely distributed substances to be found in the natural environment and constitutes the earth's oceans,
K - 3, 4 - 6. ? OBJECTIVES. • Recognize that there is a lot of water in the world, but that not very much of it can be used for our drinking water and other water supply needs. • Recognize that ground water is a very small percentage of the earth's water. • Understand how important it is that we take care of our ground water.
water and impact of fresh water availability and impact on public health. About 70% of Earth's surface is water of which 97.5% is salty water and 2.5% is fresh water. Less than 1% of this 2.5% amount of freshwater is accessible. As sea water rise's , salt water of ocean in filtrate as coastal fresh water due heavy rainfall and

The left-side bar shows where the water on Earth exists; about 97 percent of all water is in the oceans. The middle bar shows the distribution of that three percent of all Earth's water that is freshwater. The majority, about 69 percent, is locked up in glaciers and icecaps, mainly in Greenland and Antarctica.
Water is distributed across earth. Most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only 2.5% of the total. Because the oceans that cover roughly 78% of the area of the Earth reflect blue light, the Earth appears blue from space, and is often referred to
Did you know that 71% of our earth's surface is covered in sea water? Would it not be more fitting then to call it planet “Water" rather than planet “Earth"? We too are made up of water. Did you know that an individual is 70% to 90% percent water? Even the different foodstuffs you eat are mainly composed of water. The water
