A. Climate change, or global warming, is the result of human activity. The problem is that the level of gases (carbon dioxide, methane, ozone etc) which absorb the Sun's heat is rapidly rising. As a result, a kind of a gas blanket is created in the atmosphere. This gas blanket doesn't allow heat to leave the Earth's surface. The global temperature is rising. And the situation is becoming disastrous. Global warming is changing the weather worldwide. Great floods, extreme snow, disastrous hurricanes and terrible droughts are the results of global warming.

B. The population of the planet is growing fast — at the rate of 150 people a minute. The scientists say that towards the end of the 21st century there will be around 10 billion people on the Earth — or twice as many people as today. Population growth is caused by a number of economic and medical factors. Nowadays overpopulation has become one of the most crucial environmental problems. More people need more water, fuel and food. Scientists doubt that the Earth can provide all these people with everything they need.

C. Ozone is a gas that absorbs the ultraviolet radiation from the Sun. It forms a layer in the atmosphere. Ozone saves us from the Sun's rays that would be dangerous for our skin. In 1987, scientists discovered a hole in the ozone layer over Antarctica. It was a serious disaster. Though 46 countries agreed to stop the use of CFCs (chemicals that destroy the ozone layer), the situation remains quite dangerous. As the ozone layer is damaged, more and more radiation from the Sun reaches the surface of the Earth. It causes skin and eye problems. The number of cases of skin cancer and eye cataracts has increased.

D. Due to acid rain, some famous buildings and monuments of architectural and historical value in different parts of the world are in danger. The acid attacks and ruins sandstone, limestone and other materials the buildings and monuments are made of. The Parthenon in Greece, the Taj Mahal in India, and St Paul's Cathedral in Great Britain have stood for centuries but they cannot survive acid rain. Of course, people are trying to stop the damage, but the progress is very slow.

E. Genetic modification of food using biotechnology is called genetic engineering. Genetically engineered food, or genetically modified (GM) food, comes from plants or animals that have been given additional genes from other plants or animals. It is a relatively new technology that may bring many benefits to people, but there is an opinion that it can be harmful too. Some countries hide the fact that they grow GM food sources. However, people have a right to know if their food has been modified, so that they can avoid it if they want.
