Nowadays, due to population growth, the volume of rubbish and misused materials is increasing, especially household waste. Therefore, most countries with sophisticated recycling systems are trying to tackle more effective with this problem. However, some people believe that there is just one method to improve recycling, which is act enforcement. In my opinion, I agree with this approach of imposing legal restrictions to enhance recycling, but it can be more effective if the government sets encouraging rules, additionally.
