marked a turning point in human civilization, driving technological progress and economic growth.

has become increasingly severe.
As a result
Linking Words
, scientists and engineers worldwide have prioritized the search for safe, sustainable energy alternatives.
This
Linking Words
essay will discuss the urgent need to replace fossil
fuels
Use synonyms
due to
Linking Words
their environmental and
health
Use synonyms
consequences. One of the most critical reasons for transitioning away from fossil
fuels
Use synonyms
is their devastating impact on the environment. In recent years, the excessive burning of these
fuels
Use synonyms
has led to an alarming rise in carbon dioxide (CO₂) emissions, disrupting the Earth's natural balance.
While
Linking Words
CO₂ is naturally present in the atmosphere, industrial activities have significantly increased its concentration, leading to severe climate changes.
For example
Linking Words
, parts of the United States have experienced unprecedented heat waves exceeding 30°C, which were previously rare.
Such
Linking Words
extreme weather conditions contribute to natural disasters, habitat destruction, and rising sea levels, threatening both urban and rural communities. The longer fossil fuel consumption continues, the greater the damage to the planet.
In addition
Linking Words
to environmental harm, fossil fuel emissions pose a significant threat to human
health
Use synonyms
. Prolonged exposure to high levels of CO₂ and other pollutants can lead to serious respiratory diseases,
such
Linking Words
as asthma and chronic lung infections. The human body naturally expels CO₂ through breathing, but excessive amounts in the air reduce oxygen intake, leading to fatigue, dizziness, and long-term
health
Use synonyms
complications. Those living in densely populated cities are especially vulnerable
due to
Linking Words
high pollution levels. Studies have shown that prolonged exposure to air pollution can decrease life expectancy and lower the
overall
Linking Words
quality of life. Without immediate action, public
health
Use synonyms
will continue to deteriorate.
Although
Linking Words
fossil
fuels
Use synonyms
have been a reliable energy source for centuries, their environmental and
health
Use synonyms
risks far outweigh their benefits. Scientists and engineers are actively working to develop renewable energy solutions
such
Linking Words
as solar, wind, and hydroelectric power, which offer cleaner and more sustainable alternatives. Investing in these technologies is not only a necessity but
also
Linking Words
a crucial step toward securing a healthier and more sustainable future for generations to come.

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
