Everyday, so much litter and waste are poured out from houses, also pollute the environment.
The significance for controlling pollution noted that it's high time that more effective measures should be taken. Therefore, new laws should be passed to limit the amount of pollutants from factories. Moreover, in the households, there is an obvious need to reduce litter and waste. Let's make our good efforts, and the world will be a safer place to live for us.
