Pollution of rivers, lakes and seas is a major concern for people who seek to protect the environment. What are the possible causes of water pollution, and what effects does this have on animal life and human society?

Water contamination is a serious form pollution, and consequence of aqua pollution can lead to adverse effects
such
as drought, aqua erosion and contamination of marine ecology. There seem to be two main causes involved, and variety of damaging effects on people and the biosphere. The main factor is the issues of emissions from cars, factories and power stations. The emissions contain damaging pollutants
such
as carbon monoxides and dioxides which affect rainwater run-off and
thus
enter aqua cycle. Filtration and processing are not really viable options for
such
large volumes of drink, and so the drink table remains tainted with these elements over long periods.
In addition
, oil spill is the damaging biodiversity of ocean fishes and plants, due to
this
many species of fishes are near to extinction. The effects on animal life can be severe, especially which are endangered by threats
such
as poaching, habitat loss and food chain disruption. If the drink cycle is damaged, the consequence of it will affect the world.
For example
, contaminated water in India, lead to scare of drinking water caused loss of biodiversity of local animals. The impact on human society can
also
be distressing, including the poisoning of drinking water, famine or drought due to lack of safe irrigation, and long-term loss of land as we see,
for example
, after the Bhopal poisoning catastrophe in India.
Such
effects tend to have an especially grave impact on the very poorest in society, with the least resources to counter the environmental effects. To recapitulate, emissions and dumping are the main source of the problem, I believe that these two problems should be solved as soon as possible in near future.

Include an introduction and conclusion

A conclusion is essential for IELTS writing task 2. It is more important than most people realise. You will be penalised for missing a conclusion in your IELTS essay.

The easiest paragraph to write in an essay is the conclusion paragraph. This is because the paragraph mostly contains information that has already been presented in the essay – it is just the repetition of some information written in the introduction paragraph and supporting paragraphs.

The conclusion paragraph only has 3 sentences:

  • Summary
  • Restatement of thesis
  • Prediction or recommendation

Example:

To summarize, a robotic teacher does not have the necessary disciple to properly give instructions to students and actually works to retard the ability of a student to comprehend new lessons. Therefore, it is clear that the idea of running a classroom completely by a machine cannot be supported. After thorough analysis on this subject, it is predicted that the adverse effects of the debate over technology-driven teaching will always be greater than the positive effects, and because of this, classroom teachers will never be substituted for technology.

Start your conclusion with a linking phrase. Here are some examples:

  • In conclusion
  • To conclude
  • To summarize
  • Finally
  • In a nutshell
  • In general
