Saving the Environment: One Home at a Time

Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.

First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.

Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.

Third, we need to reduce waste. We need to recycle whenever possible, but shouldalso try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.

If we do our part in our own homes, we can help keep the planet from becoming more polluted.

1. Pollution is caused from the following sources except .

A. water in rivers B. water from households

C.wastes D. house chemicals

2. Recycling can help us .

A. never cut down trees B. produce more paper products

C.place garbage bins easily D. use products again and again

3. In order to save water, we can do all of the following things except .

Read the following passage and answer the questions.

Travel and tourism are very important to millions of people over the world. In every country you can find people that work in travel and tourism. Some countries need the money from tourism to help their people survive. It is necessary for these places that travel and tourism continue to expand and bring money to their regions.

However, travel and tourism have negative aspects. Planes, buses, boats and other means of transportation that carry travellers and tourists cause pollution. Moreover, some people do things on a holiday they would never think of doing at home. For example, many travellers use lot of water and electricity when they stay in hotels. They forget to turn off the lights or even leave televisions and air conditioning units on when they leave the room. On top of that, it is often difficult or impossible for travellers to recycle items, so they end up leaving large amounts of waste behind. That's why it is important for people to travel wisely and respect the places they visit.

There are ways you can travel and be environmentally friendly. Here are some tips to help you:

1. Don't throw rubbish on streets, beaches or in the countryside.

2. Don't use too much water or electricity.

3. Taste the local and national dishes of the country.

4. Buy local products or souvenirs.

5. Don't buy any products made from endangered species; sea turtle shells or bags made from reptiles or other animals.

1. Why is tourism important to some countries?

->

2. How does tourism affect the environment?

->

3. What do many people use a lot when staying in hotels?

->

4. Why do some tourists end up leaving large amounts of waste behind?
