I envision that we will have a strong system to manage waste.
People from North America always do recycling better than people from other states. Because if they do not do well, they will face a high fine. From when I lived here, I was punished by throwing garbage things. In my opinion, I think we need to cultivate everyone from their child that recycling through classification is so important that we must do to make the world more sustainable. I think countries from other states can also have a mandatory rule (accompanying with fine) about classifying household wastes.
With the strong sense of recycling, the government can then create an organization to further help the reproduction of wastes.
Also in the future, we may only have the compostable plastics in the world rather than a lot of single use plastics.
