There are number of easy ways we can do to protect our environment. First and for most, use alternatives sources like solar power or wind power to produce energy because burning fossil fuels releases a large amount of CO2, which damage the air and ozone layer. Additionally, use compact fluorescent light bulbs. Although they are more expensive than normal bulbs, they last much longer and waste an amount of money as well as electricity. Furthermore, their lights don’t harm your eyes and make you more comfortable. Secondly, reduce the number of plastic bags buy using papers or leaves to wrap things, recycle plastic bottles and other devices can also help the environment. Besides, the water sources are polluted by pesticide, herbicide, rubbish and waste, so raise the awareness of people on this issue, pass laws to punish severely those who throw them into the river. To have a fresh air, I suggest that people use public transports, walk or bicycle instead of buying a private car and motorbike. Grow more trees and flowers to beautify your houses and your cities. There are some kinds of plants that can be even considered as a treatment and nutrients sources. In conclusion, there are many methods to preserve our earth, each person needs to join hands to build the better world.
