EJEMPLO
How to Reduce Pollution and Protect the Planet
There is no doubt that nowadays pollution has a significant negative impact on the environment. This raises the issue of whether these problems can actually be solved.
In the first place, we must take into account transport. Research has proved that it has a negative influence on air quality and public health, as vehicles release harmful gases. The first step towards solving this problem would be to invest in clean public transport and encourage cycling or walking.
In the second place, it is necessary to mention, rivers and seas, since plastic pollution leads to harm to wildlife and ecosystem damage. The most appropriate response to this situation would be enforcing stricter laws against dumping waste into the water and improving recycling systems.
In the third place, the amount of energy used at home is another factor to be considered, as it contributes to global warming. As a consequence, there is a need to switch to renewable resources, such as LED lighting and solar power.
All in all, it seems to me that although pollution is continually increasing, the prospects for the future would be less grim if these solutions were applied worldwide.

OTRO TIPO DE ESSAY: EL ENSAYO DE OPINION
Hasta ahora hemos visto un ensayo de tipo problema-solución; ahora vamos a analizar otro tipo: el ensayo de opinión. Esto sirve para que veáis que, independientemente del tipo de essay, siempre hay que tener en cuenta los aspectos mencionados anteriormente.

EJEMPLO
FASHION GLAMOUR OR HARM
There is no doubt that the fashion industry has an impact on the way we see ourselves. This raises the issue of whether its effects are more harmful than beneficial.
In the first place, we must take into account appearance. Even though looking good can provide confidence, research has proved that this pressure also influences negatively on mental health, especially among young people. In addition, the situation has only been exacerbated by social media.
In the second place, it is necessary to mention the price of clothes. Designer brands can be extremely expensive leading to discrimination. As a consequence people wearing cheaper clothes might be considered less successful or less sophisticated.
In the third place, mass production is another factor to be considered as it has an impact on the environment causing habitat destruction. Furthermore, it exploits workers as factories offer workers low salaries in order to have more profits.
All in all, it seems to me that although fashion may appear glamorous it has a dark side due to the fact that its pressure creates damages, prices lead to discrimination, mass production harms the environment and gives rise to vulnerable workers.
