A Cleaner World Starts with Us

Environmental pollution is a big problem in the world today, and it’s getting worse. Even in Macao, the amount of rubbish keeps increasing every year. In 2021, the waste incineration center processed 453,152 metric tons of rubbish in total, which is a 3.6% increase from the previous year. If we don’t take action to change, the amount of rubbish might double in ten years.


One reason for this problem is our habit of using and throwing away too much. Sometimes we buy things that we don’t really need or want, and then we end up throwing them away soon after. This creates a lot of unnecessary rubbish.


What can we do to change this behavior? Each one of us can take action. First, let’s not buy things just because they are trendy or popular. It’s important to think about whether we really need something before we buy it. Second, let’s avoid buying things without thinking carefully. Impulsive buying often leads to regret and more rubbish. Third, let’s not buy a lot of things all at once, without considering if we really need them. Buying too much can result in more waste.


By being more thoughtful about what we buy and how much we buy, we can make a positive difference for the environment. Let’s work together to create a better and cleaner world for everyone.
