Smog is a form of air pollution that is produced in the atmosphere when sunlight reacts with at least one volatile organic compound (VOC). When this reaction occurs, particles (微粒)are formed in the atmosphere, and oxygen at the ground level takes in harmful chemicals, thus creating what we consider smog. Recent years have seen an increase in campaigns for the reduction of smog due to its harmful effects towards both humans and the environment. 1.

Avoid high VOC products. VOCs are chemicals that easily escape into the atmosphere through common use around the house. Check the household products to determine if they contain VOCs. 2. If you must store some, do so in a tightly covered, original container so that VOCs can’t get out.

Avoid gas-powered yard equipment. Gasoline emissions are one of the major causes of smog — whether from cars or lawn equipment. Try environment-friendly lawn equipment that can be powered electrically. You can also change the material in your yard. 3.

4. When you choose products that are made in the place where you live, it cuts down on the cost of transport which reduces emissions. Local farmers' markets and grocery stores can help you determine where items were produced. There are even many restaurants that are joining the movement towards supporting locally grown items.

Be energy efficient in your home. The less energy you use at home, the fewer pollutants that go into the atmosphere. There are many ways to reduce energy use including through lighting, heating and cooling. 5.

A. Buy local products.

B. Shop for green products.

C. It is high time that we changed our habits to make a difference.

D. There are alternatives that look real, but require less care and attention.

E. If you must use them, buy in small quantities that can be used quickly.

F. Make a community garden. Grow vegetables and fruit for your community.

G. For example, try equipment that resets temperatures on its own while you're away.
