Improved IELTS Writing Task 2 Sample (using “proliferation”)

Topic: There are more and more effective security measures in large cities to reduce crime. Does this endeavour bring more benefits than problems?

Sample Answer:
In recent years, many metropolitan areas have witnessed a striking proliferation of security measures aimed at preventing crime. While some people argue that these methods enhance public safety, I believe that their drawbacks outweigh their benefits.

To begin with, the widespread use of surveillance cameras, body scanners, and facial-recognition systems can heighten public anxiety. Although these devices are designed to create safer environments, their overwhelming presence often reinforces the perception that crime is everywhere. As a result, residents may feel constantly monitored, leading to discomfort and reduced freedom of movement. In some cases, the proliferation of such technologies raises ethical concerns regarding data privacy and potential misuse.

Furthermore, security measures do not always guarantee effectiveness. For example, improved lighting in public areas may deter criminals, but it may also assist them in identifying vulnerable victims. Similarly, the increasing popularity of personal safety devices might offer a sense of security, yet many people do not have the skills to use them appropriately during emergencies. Thus, the net effect on crime reduction remains uncertain.

A more holistic approach to crime prevention involves addressing environmental and social factors. Criminals often select targets based on time, opportunity, and environmental design. Therefore, instead of relying heavily on expensive high-tech solutions, cities should focus on reducing abandoned buildings, improving community engagement, and redesigning unsafe neighbourhoods. These preventive strategies reduce the root causes of crime rather than merely responding to them.

In conclusion, although the proliferation of security measures in large cities aims to curb crime, it may also produce unintended negative consequences. A balanced strategy that combines environmental changes, community support, and selective use of technology is more effective for long-term crime prevention.
