"എച്ച്. എസ്. എസ് ചളവറ/അക്ഷരവൃക്ഷം/Our environment" എന്ന താളിന്റെ പതിപ്പുകൾ തമ്മിലുള്ള വ്യത്യാസം

  The environment plays a major role in giving birth to a new life, in the growth of life, and the overall well being of life. Pollution endangers the natural environment and our living on earth. About 75% of the solar energy is absorbed by the earth's surface. Remaining 25% reflects back to the atmosphere. Some of this heat energy is trapped by the atmosphere for us.It provides a suitable conditions for life and is called the Green House Effect.  The greenhouse effect is provided by gases like CO2, CFC, Ozone, methane, water vapor, etc.... They are called green house gases. When the concentration of green house gases is increased in the atmosphere, they form a separate layer.  The layer traps all the heat energy which is reflected by the earth. It causes an increase in temperature on the earth's surface and is called Global Warming. The upper atmosphere contains the ozone layer which protects us from the harmful ultraviolet radiation. But CFC (chloro fluoro carbon )  produced from refrigerators, air conditioners, and the industries for cleaning computer parts cause ozone depletion. There are many consequences of ozone depletion such as, ultra-violent rays cause skin cancer, cataract, sunburn, aging of the skin, etc...  

        Environment can be saved by planting more trees, recycling,  reusing, reducing pollution, creating awareness through environmental programmes  etc... If we want to save the environment, then,,,, we should stop the exploitation of natural resources.
