Lesson 5, Ex.2

A. It may be a global issue, but when scientists across the world are asked what the effects of climate change will look like, they quickly point to our country. Of all the wealthy countries, we’re probably in greatest danger.

Due to past carbon emissions the temperatures have risen, but what we do between now and 2050 is crucial for the climate change later this century and beyond. While government assessments predict over 250,000 homes may be at risk from rising sea levels, Greenpeace says climate change will affect us beyond our front doors. Despite knowing the problems faced by one of our best-loved tourist attractions, we’re still not doing enough to protect the Great Barrier Reef. Though chemicals are damaging the reef, climate change and global warming are the greatest dangers to it. A temperature rise between 2 and 3 degrees Celsius would result in 97% of the Great Barrier Reef being destroyed. Reducing greenhouse gases emissions must be of high priority, even if the full consequences of this are not yet understood.

We’re the biggest coal exporter in the world. We might like to think that our own global carbon emissions are small (2% of the global emissions), but they’re much, much greater than that due to our coal exports to the countries of our region like Japan, South Korea, China and even to the Netherlands. If we had developed alternative, renewable energy sources, we’d have fewer problems now. We should be replacing fossil fuels with renewable power. We can become world leaders in solar, wind, marine and geothermal energies.   

B. With so many land-based species endangered, ‘the extinction crisis’ is agreed upon as a serious environmental challenge. We have already seen a fairly disturbing loss of our biodiversity. A number of introduced species have been added to the country’s native flora and fauna. The biodiversity of this large Pacific archipelago is one of the most unusual on Earth. The arrival of humans has presented a challenge for the native species, causing extinction of several. Over 50% of the local bird species are extinct, along with a species of bat and several frogs and a freshwater fish. This place is second only to Hawaii in terms of proportions of species lost. The animals are also in danger because of deforestation and – as a result – destruction of animal habitats.   

C. In 2010 there was an oil spill which is considered the worst in the country’s history. It is estimated that over 205 million gallons (gallon = 3,79 l) of oil were released into the Gulf. If the spill had been stopped earlier, the damage wouldn’t have been so great. Many species could be lost as a result. The beaches of Florida were contaminated. The harmful chemicals caused health problems in people – especially those with heart and lung problems. The real impact on the seafood industry will have long-term consequences. BP (British Petroleum) has been suffering long-term damage as they have been known as the oil company with the most environmentally friendly image. D. It is estimated that more than 1 million tonnes of textiles only are thrown away every year in this country alone. The country consumes natural resources as a terrible rate and contributes unnecessarily to climate change. Each year the population generates approximately 280 million tonnes of waste, which causes environmental damage and costs businesses and consumers a lot of money. The government and the people are doing a lot to reduce the waste some of which is reused or recycled. According to RecycleNow, the country’s recycling policy saves more than 18 million tonnes of carbon dioxide a year – equivalent to taking 5 million cars off the road! If more waste was reduced, greenhouse emissions from landfills (places where rubbish is buried) could be reduced too. Moreover, landfills are a danger to local ground water supplies. Every time it rains, water drains through the rubbish, and picks up chemicals and hazardous materials. The water collects at the bottom of the landfill, often in large amounts and can become very toxic.

E. Polar bears may only be around for another 100 years because global warming is destroying their habitat. As the Earth gets hotter, sea ice melts, and this sea ice is a huge part of the polar bears' lives. They use it as a platform to stand on when they catch seals to eat, and also walk on sea ice to get to their homes - dens. Already some polar bears, in places like Hudson Bay, are beginning to struggle because of the effects of global warming.

The sea ice is melting at a speed of 9% a year, and when it's all gone the polar bears will have to find new ways of living before they become extinct. Other bears have learnt to change their habits, but polar bears need the fat from seals to get through the winter. Arctic animals like polar bears could be completely killed off because they are also eating poisonous chemicals made by humans. Scientists have found dangerous chemicals we make have reached the food chain of animals in the Arctic circle. Poisons from plastics and electrical goods can take years to break down and disappear. But they are carried along in water for hundreds of kilometres. Eventually they get into food and water eaten by smaller animals and fish. Inuit Eskimo communities are eating the food too, which could seriously damage them. Most countries have now banned the use of these chemicals in their plastics. But some - like Russia and the US - still use some dangerous chemicals.

F. On 26 April 1986 one of four reactors exploded after an experiment at the nuclear power plant northwest of the Ukrainian city of Chernobyl. As a result, a fire burnt for nine days and at least 100 times more radiation than the atom bombs dropped on Nagasaki and Hiroshima was released into the air. 25 years later, we still don’t know the real effects of the disaster. From 2006 to 2009 a group of scientists from different countries counted and examined wildlife including insects, amphibians, reptiles, birds and mammals. The scientists say radioactive contamination in the Chernobyl exclusion zone has a serious impact on biodiversity in Ukraine and the neighbouring Belarus. According to their research, the number of mammals has decreased. Scientists in Ukraine criticized these conclusions. They say that because of the low level of human influence the biodiversity has increased. Many scientists recommend that the governments should turn this place into a wildlife haven – a natural laboratory where they can study the long-term consequences of this kind of accident. One of the scientists said, ”If people were more careful in general, the accident would never have happened. Let’s try and be more careful at least now and not jump to conclusions.”
