Writing Feedback / There is no reason why people should try to prevent extinction of animal species. Do you agree? [2]

Please help me with this essay. Thank you

It is a natural process for animal species to become extinct (eg. dinosaurs, dodos, ...). There is no reason why people should try to prevent this from happening.

Do you agree or disagree?

A sizable number of people adopt the view that the extinction of certain species namely dinosaurs is ineluctable due to unexpected natural events, so there is no point interfering in this process. Personally, I totally disagree with this point of view because apart from natural causes, I strongly believe that human causes are unequivocal.

On the one hand, it is true that a host of primitive animals such as dinosaurs and dodo ceased to exist owing to natural calamities, but it is not to say that man-made disasters are negligible. For instance, Panda experiences a population crash every year because of over poaching, thus it is now on the red list of endangered animals. In addition, thousands of acres of land are cleared to make room for human's agricultural and industrial practices. Therefore, natural habitats are severely destroyed and native species have no place to live and reproduce. As a result, as impactful as the natural catastrophe may sound, human-induced disasters are of great significance.

On the other hand, in case human practices are not the main culprit, it is highly important to spare wildlife creatures from dying out. This is because the majority of natural species are linked closely by food chain, the extinction of one kind of species may put an end to the survival of its predator, thereby sabotaging the balance of the ecosystem. Moreover, there are a few species whose genes are quite rare in the wild. The disappearance of these is synonymous with the fact that genetic materials for scientific experiments catering to human's medicinal purposes will be lost permanently, which impedes medical development.

In conclusion, human activities are the drivers pushing some kind of species to the verge of extinction. Even if these are not the chief causes, the medical and ecological merits of wildlife creatures are really noteworthy for human's life. Because of that I think it's about time taking actions to protect animals for our own sake.

Writing Feedback / The tendency of replacing conventional classrooms by virtual ones [3]

Hi everyone, please help me with this writing essay, I currently at band 6.0 and I am trying my best to achieve band score 7.0 in my writing test.

Some universities offered online courses as an alternative to classes delivered on campus.

Do you think this is a positive or negative development?

In this day and age, with the advent of the Internet, the tendency which conventional classrooms have been supplanted by virtual ones comes as no surprise. Personally, I deem this transformation contains itself both bright side and dark side.

On the one hand, online classes offers learners a host of benefits. First, students stand a better chance to enroll in a wider variety of courses which are distant away from where they live. For instance, having taken lessons provided by traditional classes, students are welcomed to join extra foreign virtual classes, which is helpful for them to fulfil their weak area of knowledge and broaden their horizon as well. Second, as far as money is concerned, aside from tuition fee, accommodation and transportation expenditure are also a heavy cross to bear for overseas students. Therefore, if more courses were held on an online platform, these expenses could be cut off significantly, which partly lightens students' financial burden.

On the other hand, this alternative form of learning also comes with some downsides. To begin with, learning on an online platform requires a certain level of commitment and discipline. If learners do not devote sufficient efforts to their study, they will fall behind with their peers in terms of academic performance. Moreover, in some rural areas there are usually deficiencies in home Internet connections and modern gadgets. Because of that, it is impossible to provide students from those places with equal access to such online classes. Consequently, in spite of the aforementioned advantages, computer-based learning fails to reach all kinds of students in our society.

In conclusion, the alternative learning has its own advantages and disadvantages. Personally, I am of the opinion that this approach should be adopted as a complementary method besides compulsory offline courses due to some justifications listed above.
