topic 1

In daily life, we waste a lot of things such as plastics, paper, etc. You can recycle these wastes instead of throwing them in a trash can. You can categorize them into non-recyclable and recyclable products and send recyclable products to a recycling company.

Ÿ Buying reusable and used items is a great way to protect the environment. By choosing used products, the demand for new products will be reduced and of course, your money will be also saved. Visit local used furniture and used appliance stores to find your needed items.

We just need to turn off unused electrical appliances and replace all of the inefficient electrical appliances, which not only consume a great amount of electricity but also have a bad effect on your pockets. Instead, using energy efficient electrical devices is the best solution for you. For example, compact fluorescent light bulbs or called CFLs are able to save up to 75% of the total energy spent for lighting your home. Although these bulbs are more costly, they can be used much longer and of course, our electric bill will be reduced.

Use your vehicles within the limit of fuel efficiency. When it is no longer in use, turn off the vehicle engine. However, if you need to start the engine again in one minute, should not turn it off as starting engine consumes more fuels than keeping the engine run for one minute.
