Riding a bicycle is very useful. But people don't always take a bicycle for the following reasons. One of the reasons is the absence of bicycle lanes. Let's look an adcantages and disadvantages of riding a bicycle and building bike lanes. The most important advantage is more simplier and safer riding for bikers around the city. The disadvantage is that there isn't enough place for bike lanes in the city. So, it will be necessary to allocate part of road or pavement. As a result, there will be no place for pedestrians and road capacity will be reduced. Besides, many pedestrians ignore road signs and go along the bike lanes. This impedes bike traffic and increases the probability of accidents. In addition, a lot of money is required for building of bike lanes since it is necessary to put asphalt, draw markings and place road signs. I believe that in future the bike lanes will be an integral part of roads and a bicycle will become an important part of our life.
Polluted their surroundings. But until now pollution was not such a serious problem. In past most people lived in uncrowded rural areas and didn’t have pollution-causing machines. But with the development of crowded industrial cities the problem of pollution has become more important. Using automobiles and other machines made pollution steadily worse. Since the 1950’s people have become alarmed with the danger of environmental pollution.Air, water, and soil are necessary for existence of all living things. But polluted air can cause illness, and even death. Polluted water kills fish and other marine life. On polluted soil, food products can’t be grown. In addition environmental pollution spoils the natural beauty of our planet.Pollution is a very complicated and a serious problem. Automobiles are polluting the air but they provide fast transportation for the people. Plants and factories pollute the air and the water but they provide jobs for people and produce necessary goods. Fertilizers and pesticides are important for growing crops but they pollute soil.Thus, people would have to stop using many useful things if they wanted to end pollution immediately. Most people don’t agree to do that. But pollution can be reduced gradually. Scientists and engineers can find the ways to reduce pollution from automobiles and factories. Government can pass the laws that would make enterprises take measures for reducing of pollution. Individuals and groups of people can work together to persuade enterprises to stop polluting environment.
