Band 4+: What are the key problems facing the world cities in the 21st century.

Note: Both the topic and the essay were created by one of our users.

According to one survey, in the 21st century, the most challenging issue in urban areas is air pollution because ten out of ten humans don’t seriously care about it. Actually, air pollution can be harmful to not only humans but also animals, so it is of vital importance to know what can be a great solution. Frankly, there are plenty of solutions, but they come from one logic, which is that everything has a solution and an answer. However, from my point of view, I totally believe we can reduce air pollution, which increases day by day, by planting trees and riding bicycles.

To start with, riding a bicycle should be used instead of cars since it can be effective for all humans with many ways of advantages, including a fresh atmosphere. Nowadays, as a technology improvement, cars are used anywhere we want to go instead of using bicycles. You may probably experience car traffic, which is so terrible with loads of smells, produces fumes, and can cause cancellations, unless you live in urban areas. By looking at this kind of case, air pollution is immersed in it most of the time. It means that air pollution from cars is a real problem. On the other hand, riding bicycles, which can be good exercise in our daily lives, can decrease our facing problem about air pollution. As a matter of fact, those kinds of things are responsible to all governments in each country in the world. They ought to encourage citizens about riding bicycles and must say people should ride bicycles to work and school and enjoy the benefits of daily exercise with protection of air pollution.

Planting trees near the house is an obvious answer to cover air pollution in urban areas. Firstly, the majority of people who want to live in big cities have been cutting trees till now for building apartments, houses, hotels, and so forth. Honestly, in their minds, they don’t think too much about what the consequences are, which can damage the environment, like nervous weather, illness, and air pollution. As much as increasing building, the trees, especially in big countries, are also losing from time to time. In fact, the air population is increasing quickly. As a result of spending loads of money on treatment, many patients, the effect of air pollution, have to go to the hospital. Thinking back on it, humans made illness by themselves. Instead of planting trees or flowers near their house, they focus on building a company or another house, which is so opposite to getting fresh air. If we plant trees, the house will be pretty good with many trees and birds, which can be a good touch in back with the environment and come up with new ideas about jobs or any case. In addition, it is all people’s duty to plant the trees and get fresh air.

How you focus on the benefits of doing exercises without using fuel will show you are a person who wants to protect the damage of pollution from transportation. And besides, you must know the plenty of trees can change a good atmosphere and a way of protecting us from depression that we face and feel. Anyway, we ought to create a good environment where we live.
