Read the passage below and decide whether the statements are TRUE or FALSE?

Many environmental problems seem so big that only governments, local authorities or big companies can deal with them. One example is global warming. We need government action to reduce emissions from coal and oil burning power stations and to develop safer sources of power. These require tough regulations and huge investment. The loss of forests and other habitat is another problem. How can we as individuals stop the destruction of the Amazon or Indonesian rain forests? Yet another example is waste. When people live in cities, they may not be able store or recycle waste, so huge landfills or incinerators are needed.

However, as consumers, we are the ones responsible for all these problems. First of all, we all need to consume less power. We need to turn off lights, replace inefficient bulbs with low-power ones, and not leave equipment on standby. Secondly, we need to control our surging populations. Each of us can make a decision regarding family size. This has a huge impact on the size of our cities and the need for food and more agricultural land. In addition, we need to consider eating less meat and more vegetables and fruit, in order to reduce the amount of land needed for meat. Generally, the main step we need to take is to live more simply. We need to reduce our consumption, recycle, and reuse.

Question: Turning off lights and equipment, and using low power bulbs helps to save electricity.

A. True

B. False

Car: the burning of petroleum is one of the biggest sources of carbon monoxide that causes global warming. CO thins the ozone layer, which protects us from the sunrays. So try to walk, cucle, or use public transportation.

energy: the biggest use of home energy is for heating and cooling homes. it costs alot of money. so turn the heat down, especially at night. replace regular light bulbs with low energy light, which use less energy.

water: showers use a lot of water. buying a special " low-flow" shower head or taking shorter showers can cut this use in half
