The above are some advantages and disadvantages of science and technology.
1 They are air pollution, water pollution, and land pollution.
2 - The causes of one type in my area is Factory emissions
- Affect: + Make acid rain
+ Affects Respiratory system of people
+ Air pollution
3 - Clean the school grounds and in the classroom
- plant a lot of trees
- dump garbage in the trash
Most of the air pollution results from the burning of fossil fuels, motor vehicles, factories, aircraft and rockets. This can cause acid rain which damages water, soil, and vegetation. Air pollution also contributes to the greenhouse effect which can lead to a series of environmental problems such as global warming, polar ice melting, rise of sea levels and loss of land.
Water pollution is a result of dumping pollutants such as detergents, pesticides, oil, and other chemicals in rivers, which makes the water unclean or contaminated. Rubbish blockages in rivers can also cause pollution.
Nowadays most people prefer living in the large cities to living in a small community because of the benefits large cities has brought to their lives. So how about living in a small community? What were advantages and disadvantages to be a part of a small community in the past.
I believe there were 3 main benefits. First;y, as living in a region, people living in that area surely knew their neighborhood well, so they easily interacted with everyone when they faced a problem or needed something. Besides, having people stay by side by side each other and helped them out when facing difficulties, which made me would rather choose small community’s life than a larger one. Secondly, the limited population made them unwilling to do crime. This meant the crime rate remained very low because it would be detected soon if you were involved in stealing or any relative activities. Finally, the manage of government was much more effective and forceful than the big cites’s lives. Owning to small population, the government were in charge easily.
I think many of the disadvantages were education. It could be denied that the development of education is supported by the population in one area. That is why it was rarely found a high quality education facilities in a small community. However, in my view, lacking of information was also as serious as lacking of education. Because it’s hard to get information from outside their region, people living in a small community was usually considered as a fogy people. Therefore, we can’t deny the importance of receiving information and knowing what happens around the world.
In my opinion, living in small community is perfect or middle-age people and the old. However, for the young, they might choose to live in a large city. in fact, living in a small community is not really bad because we can form a strong relationship and you’ll never ever alone.
The key to environmental sustainability is thinking globally and acting locally. Pollution prevention is about making smart choices–both in what we buy and in how we use products. It involves looking at the causes of waste and pollution and figuring out how to prevent them.
Due to the number of people in attendance and the many activities taking place throughout the day at a school, larger quantities and more types of waste are produced at schools than in homes. Students, administrative staff, teachers, janitors, and contractors all use energy, water, and even hazardous chemicals, throughout the school year. Therefore, schools are a great place to introduce pollution prevention (P2) ideas on how to reduce or eliminate pollution and waste, which can be harmful to humans and the environment and costly to school budgets.
Where is waste generated in schools?
Energy: used in lighting, office machines, heating, air conditioning, transportation
Hazardous chemicals: found in cleaning supplies, aerosol cans, paints, science labs (mercury), art classrooms, janitors' storerooms
Pesticides: used on school grounds, gyms, kitchens, locker rooms
Water: used in bathrooms, kitchens, locker rooms, sinks in classrooms, outdoors
How can your school prevent pollution?
All students, teachers, administrators, and janitors should ask themselves if there is a better way to do their job–a way that will not create waste. In other words, everyone at the school should adopt a "less is best" attitude.
Some ways that students, teachers, and school administrators can prevent pollution at school include the following:
Bike, walk, or share rides to and from school.
Request that drivers of school buses and cars turn off their engines while they wait to pick up or drop off students.
Use less toxic glues, paints, markers, and other materials.
Start a book exchange.
Collect unused school supplies at the end of the year for reuse next year.
Buy unbleached, recycled paper.
Organize a tree-planting event on school grounds, or organize a school-ground naturalization project to create opportunities for outdoor learning through hands–on experience.
Use both sides of paper.
Take a "litter-less" lunch to school, by using reusable containers and a re-usable lunch bag.
Use refillable pens, printer toners, and ribbon cartridges.
Turn off machines when they are not in use.
Organize a paper, glass, plastic or metal recycling project.
Eliminate the use of pesticides and chemicals on the school playing fields.
Encourage students to implement pollution prevention principles that they have learned at school in their homes.
Form a pollution prevention team.
Celebrate Environment Week and participate in a community event.

talk about the ways of reducing pollution at your school
Our school looks so dirty these days. And it's time to save our school before it's too late. There are many ways of protecting the environment at our school.
Firstly, we should reduce and reuse bottles, cans and plastic bags because they are hard to dissolve. If we do so we can save energy and even make more money from selling those things.
Secondly, we shouldn't throw trash on the school ground because it doesn't only cause pollution but also do harm to our health and make us get sick.
Thirdly, we should make sure our lunch table is clean before we leave. Don't leave milk cartons, napkins or pieces of food on our table. Push in our chairs as we leave the table and remember to check the floor to make sure we didn't drop anything.
Finally, we should go to school by bike, on foot , or public transport to reduce exhaust fumes and save energy.
In conclusion, reducing pollution at our school means that we are improving the quality of our study time.
