What about using energy-saving bulbs instead of 100-watt light bulbs?

Our surrounding environment is so polluted that we should follow specific approaches to tackle this problem. To begin with, each of us should use water wisely. That can simply be the instant repair of leaky faucets and pipes because a dripping faucet can waste as much as 5 liters a month. Besides, using the shower instead of taking a bath can save up 50% of the water consumed. Plus, responsible disposal of waste should be put into practice in every household. To be more precise, organic trash and scrap metal are to be classified and discarded in different bins. Moreover, it is advisable to reduce our electricity consumption. By turning off the light when going out of the room or using energy-saving devices, we can save not only our money but our environment as well. To sum up, the concerted effort from each individual in saving the environment will yield the best results.
