1.Earth Day

Earth Day was started in 1970. It was organized to help raise environmental awareness to the general public.It helped spark the creation of the Environmental Protection Agency.

By the year 2000 there will be6.3 billion people on the planet. There was almost twice as much land devoted to urban life in 1990 than there ws in 1970.

The Earth Day provides a special day to remind the population to take care of the Earth.

2.Going Green

When Jeffrey Hollander launched his seventh generation live of products ten years ago, the market for nontoxic household cleaners and recycled paper products was virtually nonexistent. Today, it's a booming businness.

The niche is environmentally friendly,or so called green products.

A green product is one that has less impact on the environment. So that means that it might use less resources, it may create less waste and be more evergy efficient for example.

An average home might have an evergy bill of 1300 dollars a year. If all the products, all the appliances in the home were Energy Star, that home could save about 30% a year, and for the average home in the U.S. that might be around $400 a year.

3. Description of the earth:

Earth means many things to the people who live on it. To a farmer, Earth is rich soil. To a road builder, Earth means mountains of hard rock. For a sailor, Earth is water as far as the eye can see. A pilot's view of Earth may include part of an ocean, a mountain, and patches of farmland. An astronaut speeding through space sees the Earth's round shape and the outline of lands and oceans.

4. Car Pollution

Refining, distributing, and burning a gallon of gasoline produces about 30 pounds of carbon dioxide. If every car in the U.S. were replaced by one that was 10 mpg more fuel-efficient, carbon dioxide emissions would be reduced by 250 million tons per year, and the nation's annual contribution to global warming would be cut by nearly 20 percent.
