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.

Using homemade compost is cost – effective as ________.

Read the following passage and choose the best answers to the questions.

          In many ways, the increasingly rapid pace of climate change is a direct result of the growth of the human population. In the last 100 years, the world population has more than tripled. Obviously, this has meant that the world has needed to produce three times as much food, energy, and other natural resources.

          In addition, the average person uses more energy and natural resources than the average person one hundred years ago, meaning that the rates of consumption are actually much higher than just the increase in population would imply. 

All of these activities: food production, energy usage, and the use of natural resources, contribute to climate change in some way. The greater amounts of oil and other fuels burned to create energy release chemicals which add to global warming. In order to produce more food, farmers cut down trees to gain more land for their fields. In addition, we cut down trees to build the houses needed for a larger population. Those trees are an essential part of controlling global warming.

          In addition to a growing population, the world also has a population that desires a higher standard of living than in the past, and a higher standard of living requires the use of even more natural resources. For example, China is the world’s most populous nation, with 1.3 billion people. Currently, the standard of living for most of those people is far below that of people in first world nations. Therefore, the average Chinese citizen uses far fewer natural resources and less energy than the average citizen of the US or Japan. If every Chinese person attains a first world lifestyle, the amount of energy and natural resources needed in the world will double, even if the standard of living in every other nation on Earth remains the same as it is today.

The word “pace” in the passage is closest in meaning to _____.

We are all slowly destroying the earth. The seas and rivers are too dirty to swim in. There is so much smoke in the air that it is unhealthy to live in many of the world's cities. In one well-known city, for example, poisonous gases from cars pollute the air so much that traffic policemen have to wear oxygen masks.

We have cut down so many trees that there are now vast areas of wasteland all over the world. As a result, farmers in parts of Africa cannot grow enough to eat. In certain countries in Asia there is too little rice. Moreover, we do not take enough care of the countryside. Wild animals are quickly disappearing. For instance, tigers are rare in India now because we have killed too many for them to survive. However, it isn't enough simply to talk about the problem. We must act now before it is too late to do anything about it. Join us now. Save the Earth. This is too important to ignore.
