Práctica evaluable 3. Problem/solution essay.

     Pollution and the greenhouse effect are issues that become more and more important everyday and we do almost nothing to solve it, but it's not as difficult as many people say. The Earth's atmosphere is composed of some different gasses as nitrogen, oxygen, water steaming a small percentage of CO2, but since the 21th century until now, this percentage is increasing, causing the greenhouse effect.

     We could reduce CO2 emissions by limiting the usage of fossil fuels like coal or petrol, but this solution would affect negatively to many enterprises and the economy would get worse. Another way to reduce CO2 emissions could be by making electric vehicles more popular and offering people some king of help to buy one, but this solution would take a lot of time because not every car brands have developed their own one, so they would be in a hurry to produce that vehicle and they could not be as efficient as they're supposed to be, in addition to be badly developed because of the hurry. My last proposal consist of helping enterprises to change their fuel-powered engines to some electric ones, so they would be more efficient and many other enterprises would try to make the same in order to be able to compete with their competitors.

     In conclusion, changing our planet's future is in our hands and it's still possible, I'm not here to fix the world but, with small ideas like those and a positive mentality we could do a lot for our planet, the only thing I know for sure is that, if we don't change our mind, this problem is not going to get solved and maybe, it will be too late when we try to do something.
