doesn't pollute in the city has petrol engine for open road | Hybrid |
E. You are going to write an essay with the title: How can we reduce pollution from cars in cities? In the essay you will present several solutions to the problem of pollution. How can you join the different parts of the essay?
- How can we solve the problem of overfishing?
- The North Sea around Britain used to be one of the richest seas in the world for fish.
- But now there is a problem. There has been too much fishing, and now the fish are almost all gone.
- Pollution in the water has made the situation worse- fish cannot breed in dirty water.
- What is to be done?
- One possible solution is to stop fishing completely for a few years. This would give the fish time to breed and increase their numbers.
- But, of course. this would be terrible for fishermen. They would lose their jobs.
- An easier solution might be to reduce the quantity of fish that we catch. Then fish and fishermen could survive.
- There is another way forward: fish farming. It is possible to breed some types of fish in fish farms. If we do this, we don't need to catch wild fish.
- Something else that we must do is stop the pollution in the North Sea. Even if we are not fishing, it is important to have clean seawater - for people and for animals.
Write 100-120 words about how to reduce cars pollution?
- Road transport especially cars is one of the biggest sources of air pollution in the world.
- The air pollution from cars causes a variety of human and environmental problems that could be avoided or at least easily reduced.
- One possible solution to this problem is to encourage people to walk or ride a bicycle in short journeys instead of driving a car.
- An easier solution might be to use public transport. Travelling in trams, buses and trains is a quick and relaxing way to reach our destination.
- There are another ways such as: using hybrid cars and lead-free petrol, sharing other people in the same car, driving more gently and maintaining the car.
