Help me add some Expo elements to this team activity plan.

We can publicize the environmental awareness of recycling and the environmental knowledge of simple garbage classification through such an activity. What's the point of doing it? It is not difficult to see from the following data: 1995, the domestic garbage removed by the national sanitation department exceeded 1 100 million tons, which was four times that of 1979, and only one city in Beijing produced10.2 million tons of garbage every day. These rubbish are generally piled up in the open air or sent to the suburbs for landfill. They not only occupy land, pollute water bodies, but also waste the few earth resources left. Garbage siege has become an increasingly serious environmental hazard in China. Therefore, in a sense, promoting the environmental protection knowledge of garbage classification not only protects the earth and the environment, but also promotes the sustainable development of China!

First of all, we can group students and cooperate with each other. Some students can find information, typeset and beautify posters, and we can also mobilize everyone in the class to be two pairs of models (that is, four models). In this way, everyone's workload is not big, but many models can be made to help publicity activities, and all students can contribute to environmental protection publicity. It can be said that they can kill two birds with one stone Then print a poster, choose a vacant lot where pedestrians pass (of course, be careful not to block the passage of pedestrians), and pedestrians can introduce each other and give away models when they stop to look at the poster, so that pedestrians can remember the importance of garbage sorting.

China wastes 25 billion worth of resources every year! These resources are neither oil nor natural gas, nor high-tech products, but domestic garbage produced by every family every day. Therefore, through our publicity activities, people can properly classify their garbage, which not only saves huge waste of resources, but also makes those waste that can be used but not used no longer become the source of secondary pollution. Although we affect a small number of people, with the improvement of people's awareness of environmental protection, more and more people will join the ranks of garbage sorting, which will also make foreign friends visiting during the World Expo leave a good impression on China people and promote sustainable development. Why not?

Let's start with the Shanghai World Expo that we are most familiar with. The materials used in some pavilions in the Expo Park are low-carbon and environmentally friendly, and energy-saving and carbon-reducing measures such as solar energy and wind power have been adopted. Even this is not enough. They planted flowers and trees on all the vacant spaces in the exhibition hall, which not only beautified the environment, but also made us feel the interest of nature.
