Our environment is in trouble. People and industries are polluting the air, rivers, lakes and seas. There are many things you can do to help the environment. Here are a few.
Firstly, the burning of petroleum is one of the biggest sources of carbon monoxide (CO) that causes global warming. CO thins the ozone layer, which protects us from the sun’s ray. So try to walk, cycle or use public transportation.
Secondly, the biggest use of home energy is for heating and cooling homes. It not only consumes much energy but also costs a lot of money. So turn the heat down, especially at night. Replace ordinary light bulbs with energy-saving light bulbs, which use less energy.
Finally, showers use a lot of water. Buying a special “low-flow” shower head or taking shorter showers can cut this use in half.
