Some people say that the main environmental problem of our time is the loss of particular species of plants and animals. Others say that there are more important environmental problems. Discuss both these views and give your own opinion.

Шаг первый: перефразируем задание + формулируем 1 аргумент за и 1 аргумент против во вступлении + выдвигаем наше мнение (какую сторону поддерживаем):

At present, ecological dangers lie at the heart of the most worrying societal concerns. There are those who are primarily concerned about the reduction of wildlife resources, while others draw undivided attention to various adverse consequences of environmental contamination. I entirely support the latter view because the damage caused by this negative development is irreversible. Firstly, this essay will discuss the contaminated environment as an immediate danger for all components of the global ecosystem, and secondly, it will analyze the risk of starvation as a detrimental consequence of reduced flora and fauna.

Шаг 2: поясняем преимущество  + пример для подкрепления вашей позиции

One the one hand, those who are deeply worried about a rapidly increasing pollution rate take into account long-lasting undesirable effects that this deterioration leads to in the long run and I agree. Not only is the global temperature rising at an abnormally rapid rate, but this also inevitably results in water disbalance. A prime example is numerous European cities that, being exposed to unbearable scorching heat at present, are also known to be likely to be flooded by the end this century in the aftermath of the uncontrollable melting of the Ice Cap.

Шаг 3: поясняем другую сторону + ослабляем этот аргумент предложением “However, it is clear that…”:

On the other hand, loss of biodiversity is often believed to be the most critical concern as it puts humankind at risk of starvation. Multi-leveled as the ecosystem is, it is thus increasingly vulnerable to any, even minor, interventions. If it were not for a dramatic reduction in local flora and fauna, an overwhelming majority of essential food chains would not be destroyed. However, this bioresource is known to be renewable, and its ability to recover are a key to maintaining environmental balance.

Шаг 4: делаем вывод о преимуществе (дублируем нашу позицию в заключении)

In conclusion, though people may vary in their opinions, I am firmly convinced that it is high time people took a stand and need to be proactive when it comes to preventing global warming as the most worrying issue facing the world.
