Part One: Introduction of New Knowledge

When we usually watch TV, in addition to watching cartoons and other entertainment programs, do we also watch social programs? Do you know the dangers of acid rain? What's going on with the smog?

What we know about environmental pollution PPT, part 2: exploring new knowledge

In our lives, besides "white pollution", what other types of environmental pollution are there? Please select an item for investigation and complete the questionnaire.

Our group conducted a small survey on pesticide contamination, and the following are the results of our survey.

What we found: Pesticide pollution occurs in our daily lives. The fruits and vegetables we eat every day at home are contaminated by pesticides to varying degrees.

I found that every time my grandma came back, she had to soak the vegetables in water for a long time.

My mother said that you need to peel the fruit before eating it because the pesticide residue on one side of the fruit peel is very strong.

Cause: Unscientific use of pesticides, such as excessive and excessive use of pesticides, are important causes of pesticide pollution.

Uncle Wang, an agricultural technician in the village, told us that many people fail to seize the best prevention and control period. They usually do not apply pesticides in time. They do not apply pesticides when the pests are not seen. They apply pesticides only when the pests are seen. They use large amounts of pesticides when the pests are spreading. This not only has a poor insecticidal effect, but also causes a lot of pollution.

Our advice: How can you reduce pesticide pollution? Our group has reached a consensus.

1. Minimize the use of pesticides and use green and environmentally friendly methods to prevent and control pests and diseases.

2. When using pesticides, you must use nationally recognized and qualified products.

3. Use pesticides strictly according to instructions.
