New Hampshire's House of Representatives endorsed marijuana legalization Wednesday, but that doesn't mean the state will be the third to legalize pot. Rep. Steve Vaillancourt, a Republican sponsoring the legalization bill, tells U.S. News the state will not adopt his proposal in 2014.
The ocean holds 97 percent of the Earth's water; the remaining three percent is freshwater found in glaciers and ice, below the ground, or in rivers and lakes. Of the world's total water supply of about 326 million cubic miles of water, over 96 percent is saline, found in the ocean.
If the amount of fresh water is constant on Earth then why do we need to conserve it? What is the percentage of fresh water on the Earth? Why does on the earth only 3% fresh water and rest 97% about sea water? Why Earth contains so much saline water than fresh water? Is the total amount of water on Earth always constant?
