The students facing the blackboard are asked to describe the meaning of the word verbally or with body language. They can elaborate on the purpose, scope of use, and role in human production and life, but they cannot say the word. The word in Chinese or translated from Chinese to English, students with their backs to the blackboard can guess the word. Each group has a time limit of 1 minute. No points will be given for those who exceed the time or violate the rules during the game.

Utilization and protection of natural resources PPT, part three: thinking about countermeasures

Countermeasure 1 - Save and reuse

Countermeasure 2 - Pay attention to resource renewal and vigorously develop new energy and new technologies

A: Electronic fashion

Electronic wedding invitations are becoming a fashionable and environmentally friendly way of "notifying happiness". More and more young people choose to send online electronic wedding invitations instead of traditional paper invitations when they get married. According to statistics, every 4,000 wedding invitations produced is equivalent to cutting down an adult tree. Electronic wedding invitations not only save money but are also more environmentally friendly.

B: "Stingy" fashion

Reusing office paper has become a common practice in Hong Kong, even in the Chief Executive's Office. The Hong Kong government stipulates that the front and back sides of office paper used by civil servants must be fully utilized before it can be thrown away as garbage for recycling. This behavior has reduced the Hong Kong government’s office paper consumption by nearly 1/3.

C:Tree planting activities

According to estimates, a 20-year-old tree can only produce 3,000 sheets of A4 paper. For a student, 3,000 sheets of A4 paper are far from enough for one year. This means that humans use trees faster than they grow. Much faster. Arbor Day activities speed up the renewal of forest resources and prevent their numbers from decreasing drastically.

D: The whole body is a treasure

In the Heilongjiang area, while using wood to produce large objects, they also use tree roots, branches, bark, leaves and other residues as the main raw materials to make woven handicrafts, making full and effective use of forest resources, and not only winning a wealth of Economic income has also greatly improved the utilization of local forest resources.

E: "Rotten" wood can be "carved"

Some cities in my country have established waste wood recycling mechanisms. For example, the new project in Anhui uses wood powder processed from old wood, branches, etc. to make new products; the Jiangsu old wood market reprocesses old wood, old doors and windows, etc. that were removed during urban reconstruction and turns them into new products. doors, windows, and room materials.
