An increasing number of people use cars for commuting and traveling. What problems are caused by this and do you agree that people should be discouraged from using cars?
It is true that cars have become an increasingly popular means of transportation, particularly over the past half century. There are a number of threatening issues caused by this trend, and I completely agree that people should drive less.
The rise in cars is problematic for various reasons, the most critical of which is its contribution to climate change. Every day, millions of cars emit vast amounts of greenhouse gases, which trap more of the sun’s heat on Earth over time. As a result of this, ice caps melt faster, sea levels rise, and extreme weather conditions become common. Millions of human lives are therefore at stake. Secondly, cars are a major contributor to air pollution, which damages our lungs and causes premature death. For example, studies have estimated that air pollution can reduce life expectancy by more than three years. Other effects of the rise of cars include more traffic jams, noise, and car accidents. These may seem like less serious consequences, but they are nonetheless disruptive and harmful to everyday life.
Because of these issues, I strongly agree that we should discourage the use of cars. Climate change, in particular, could actually doom the planet once we’re unable to reverse global warming, and that critical point is approaching fast. Moreover, better alternatives to cars already exist. Instead of driving cars, people could take public transportation, which is often cheaper, eco-friendlier, safer, and even faster. For instance, it takes me just twenty minutes to take the subway from my home to my high school, and I barely need to spend anything. Another way to reduce the use of cars is to try to increase telecommuting. People who can work, meet, or learn from home should be encouraged to do so through online conferences or classes.
In short, the popularity of cars poses a great threat, but it’s a challenge that we can overcome if we embrace other ways to travel and interact with each other.
