Sixth grade proposal to the Environmental Protection Agency

Dear Director of the Environmental Protection Bureau:
Hello!
Nowadays, the city of Shenzhen is getting better and better, which is the hard work of sanitation workers. However, it is a pity that in some places in Shenzhen, it has been found that flies are flying all over the sky, garbage is piled up everywhere, and even some places smell the stench of garbage when they are far away from the garbage.
It is understood that a neighborhood near me was a small garden. Later, the garden was demolished and a community was built in one of the places. Later, the domestic water in the community was discharged into the open space. Sometimes people in the community throw garbage into it for the sake of convenience. Later, someone cleared the rubbish here and set up a brand there: it is forbidden to throw garbage here. At the beginning, no one really littered here. However, within a few days, some small vendors came here to sell food and throw some unwanted fruits and vegetables on the ground. Over time, the fruits rotted and stinked, and the people in the community threw the rubbish there. In addition to domestic garbage, there are construction waste such as rubble and stones on the open space. These garbage will not only make the nearby air worse, but also breed insects such as mosquitoes and flies that transmit diseases. So, I want to give you some suggestions:
One: Send people to clean up the garbage on the open space.
Second: to promote the importance of environmental protection to people, and let the public no longer throw garbage in the open space.
Three: Put more garbage bins near the community, or build garbage stations so that the public can solve the domestic garbage.
Fourth: Regularly inspect the streets, and fines if someone throws litter.
For the bright future of Shenzhen, I hope you can adopt my suggestion.
Thank you!
