Unit 11

Read the following passage and choose the best answer to each question.

Water pollution is one of the biggest threats to the environment today. There are several sources of water pollution ranging from sewage and fertilizers to soil erosion. The impact of water pollution on wildlife and their natural habitat can be immense. There are also a number of things that the average person can do to help stop water pollution.

We should conserve the soil because soil conservation influences water pollution through erosion. As soil is eroded by water, it transfers sediment from the land to the body of water, which is polluted by the chemicals in the sediment. Phosphorus and industrial chemicals can be pulled into water through soil erosion. When phosphorus levels in water become too high, they can lead to algae blooms that can cause massive fish deaths and make water unsafe for human use. The best way to prevent soil erosion is to keep the banks of rivers well-covered with plants or trees. Planting trees can have a significantly positive impact on the reduction in soil erosion.

The oil used to lubricate engines in all types of machines needs to be changed regularly. When the oil is changed, it presents a number of environmental hazards if not disposed of properly. When a leaky engine releases this oil into the street, it runs to the sewer and makes its way into waterways.

Wherever you see a lot of human recreation, you will almost always see lots of evidence of human use. Wrappers, bottles and other trash are unfortunately a common site at many well-used beaches and rivers around the world. It should be fairly obvious that the trash from these places often ends up in waterways and can cause pollution. Plastics are an especially big issue when it comes to water contamination at beaches and waterways. Picking up litter wherever you find it is honestly the best, fastest way to do your part to stop this type of water pollution.

Organize cleaning parties with local people to make the reach larger. Get businesses involved as sponsors who will donate prizes to the person who collects the most trash if you're having a hard time finding people to sign up to help.

It is estimated that the consumption of plastic by humans is between 250 and 300 million tons a year. About 80% of the plastic in the oceans came from the land. Using alternatives to plastics or using "less disposable" plastics whenever possible can have a surprising impact on ocean pollution. The fact that plastic is cheap and useful for different purposes makes it obvious choices for many people.

Soil erosion can lead to water pollution because _______.

1. soil can be eroded by rain water
2. soil erosion can occur naturally everywhere
3. chemicals in the sediment from the soil erosion will pollute water
4. massive fish deaths will make the rivers unsafe for human use

In the world today, particularly in the two most industrialized areas, North America and Europe, recycling is big news. People are talking about it, practicing it, and discovering new ways to be sensitive to the environment. Recycling means finding ways to use products a second time. The motto of the recycling movement is "Reduce, Reuse, Recycle".

The first step is to reduce garbage. In stores, a shopper has to buy products in blister packs, boxes and expensive plastic wrappings. A hamburger from a fast food restaurant comes in lots of packaging: usually paper, a box, and a bag. All that packaging is wasted resources. People should try to buy things that are wrapped simply, and to reuse cups and utensils. Another way to reduce waste is to buy high-quality products. When low quality appliances break, many customers throw them away and buy new ones - a loss of more resources and more energy. For example, if a customer buys a high-quality appliance that can be easily repaired, the manufacturer receives an important message. In the same way, if a customer chooses a product with less packaging, that customer sends an important message to the manufacturers. To reduce garbage, the throwaway must stop.

The second step is to reuse. It is better to buy juices and soft drinks in returnable bottles. After customers empty the bottles, they return them to the store. The manufacturers of the drinks collect the bottles, wash them, and then fill them again. The energy that is necessary to make new bottles is saved. In some parts of the world, returning bottles for money is a common practice. In those places, the garbage dumps have relatively little glass and plastic from throwaway bottles.

The third step is being environmentally sensitive is to recycle. Spent motor oil can be cleaned and used again. Aluminum cans are expensive to make. It takes the same amount of energy to make one aluminum can as it does to run a color TV set for three hours. When people collect and recycle aluminum (for new cans), they help save one of the world's precious resources.

Which is described as one of the most industrialized areas?

1. cautious
2. friendly
3. logical
4. responding

It was a waste when customers buy low-quality products because .

1. customers always change their ideas
2. they have to be repaired many times
3. people will soon throw them away
4. they are very cheap

Read the passage below and choose one correct answer for each question.

There are many ways that recycling helps the environment, and even the smallest step can have significant results.

The environmental problem of landfills is a difficult issue to fix. As more waste is put into landfills, the bigger the problem gets. Wastes that are not biodegradable or are slow to decompose can remain in landfill sites for centuries, often emitting gases that could be harmful to the environment. Keeping paper out of landfills is just one way that recycling helps the environment.

Recycling items often uses less energy than manufacturing products from natural sources. Making paper that is using recycled pulp, for instance, is much less energy intensive than using new wood. While there are benefits to growing trees because of the carbon dioxide that they consume, it will be the damage that is done to the environment by putting paper in landfills and using energy to produce new items.

Waste in landfills emit gases as it rots. This can pollute the environment. Anyone who has passed a landfill site during hot weather will be familiar with the unpleasant smell and flies that can be found near a landfill site. Reducing the items in landfills will help to reduce the pollution that it causes. Recycling wastes also typically emits less carbon dioxide and carbon monoxide, thus reducing the carbon footprint of a product.

Another benefit of recycling is that there is often a significant cost saving to be made when using recycle goods. Recycling leaves and grass, for instance, is a great way to make compost. Using homemade compost is obviously a lot cheaper than buying compost and this is a useful way to save money. Saving money through recycling ultimately helps the environment.

Recycling is just one of many ways that we can help the environment. Every step that we take, however small, is one more towards helping and supporting the environment in which we live. Getting everyone involved, from children to adults, can help produce a better environment for many generations to come.

The environmental problem of landfills is a difficult issue to fix because________.

1. wastes can make the soil biodegradable or slow to decompose
2. we have difficulty keeping paper out of landfills for recycling
3. the problem gets bigger and more waste is put into landfills
4. wastes can remain in landfill sites for centuries, often emitting harmful gases

The environmental problem of landfills is a difficult issue to fix. As more waste is put into landfills, the bigger the problem gets. Wastes that are not biodegradable or are slow to decompose can remain in landfill sites for centuries, often emitting gases that could be harmful to the environment. Keeping paper out of landfills is just one way that recycling helps the environment.

Recycling items often uses less energy than manufacturing products from natural sources. Making paper that is using recycled pulp, for instance, is much less energy intensive than using new wood. While there are benefits to growing trees because of the carbon dioxide that they consume, it will be the damage that is done to the environment by putting paper in landfills and using energy to produce new items.

Waste in landfills emit gases as it rots. This can pollute the environment. Anyone who has passed a landfill site during hot weather will be familiar with the unpleasant smell and flies that can be found near a landfill site. Reducing the items in landfills will help to reduce the pollution that it causes. Recycling wastes also typically emits less carbon dioxide and carbon monoxide, thus reducing the carbon footprint of a product.

Another benefit of recycling is that there is often a significant cost saving to be made when using recycle goods. Recycling leaves and grass, for instance, is a great way to make compost. Using homemade compost is obviously a lot cheaper than buying compost and this is a useful way to save money. Saving money through recycling ultimately helps the environment.

Recycling is just one of many ways that we can help the environment. Every step that we take, however small, is one more towards helping and supporting the environment in which we live. Getting everyone involved, from children to adults, can help produce a better environment for many generations to come.

Recycling can help to solve the problem of pollution because________.

1. it reduces the carbon footprint of products
2. it helps people stay far away from landfill sites
3. it helps people forget the unpleasant smell and flies
4. it reduces biodegradable wastes at households
