Problem/Solution essay - Practice 3

           Pollution is a huge problem, it affects everything, every live being and the environment. Other energy sources are needed or we will have troubles, furthermore, the world is already in trouble. The environment has been changed, forest are destroyed, seas and rivers polluted, glaciars are melting and animals are endangered. We need to try some green-ways to live and start to change details in our lives, starting by pollution of our cars and motorbikes.

            One solution to avoid pollution is use bikes instead of cars. Bikes are a healthy and green way to move without causing any harm to earth. A problem of the use of bikes is the fact that many cities are not designed in a good way to ride a bike there, and that made ride a bike at cities something a little dangerous. Added to this, prepare a city to be redesigned is really expensive.

            Moreover, other solution is to use electric cars. The use of this cars are cleaner than cars and less expensive, But, to construct electric cars they need to work with light weight kind of materials, which is quite bad to the environment because work with this metals caused more pollution and they are need light weight metal because the batteries of this cars are really heavy.

             From my point of view, the "ride a bike solution" is better. I know that is a really big change, to drive bikes instead of cars, but we need a redical change to conserve the environment and make the earth a better place to live.

             To conclude, due to the fact that pollution is a big problem to the world and to us, we need to start making a change by our own. The most important thing to start change the world is change ourselves.
