Mangroves Mangroves are various types of trees up to medium height and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics – mainly between latitudes 25° N and 25° S. Importance of Mangroves a. Buffer Zone between the land and sea. b. Protect the land from erosion. c.

the earth or the people‚ but it does the exact opposite. One problem is the hole in our ozone layer. The ozone’s purpose is to block harmful ultra violet rays from the earths surface. These UV rays can cause skin cancer and can also produce the green-house effect. The hole in the ozone layer is caused by a man made product called aerosol. In aerosol there is a thing called CEF‚ this is what eats away at the ozone. CEF’s can also be found in refrigerators . Aerosol is a product that is used in many

Oh‚ and people cannot beat the heat of Los Angeles‚ which is nearly 134 degrees due to the large hole within the ozone layer. Later a walk down to Hollywood Boulevard to get high off the emissions of the cars along with the meth addicts on the side of the rode would be fun. Then that one guy with his black hummer could probably pass on up with his “I Heart the Earth”

Researchers believe that global warming is real concluding that hotter temperatures‚ ozone thinning and natural disasters are effects of this situation. People may notice that temperatures have been increasing over the years. The United States Environmental Protection Agency had stated “According to the U.S. Global Change Research Program

Keeping temperate forests are important‚ because they serve a big part in reducing the amount of carbon dioxide in the air. Using non-environmentally safe products is big problem too. We use things such as hairsprays‚ which are aerosols‚ which form holes in the ozone layer. This raises the temperature and also keeps infrared light from leaving the earth

This is caused by the use of CFC gases in aerosols‚ refrigerators and the manufacture of polystyrene foam. The ozone layer protects us from harmful ultra-violet radiation from the sun. A depletion of this layer could lead to increased skin cancer. Nuclear radiation. The fear is that accidents or sabotage at nuclear power stations could cause dangerous
