2019年5月11日雅思写作：Most of the world's problems are caused by overpopulation。 To what extent do you agree or disagree?
Over the last century there has been a remarkable rise in population growth around the world. This dramatic increase in the number of people on the planet has caused many critical problems. This essay will address those problems, and outline my agreement with the position that, as a matter of the utmost urgency, the world has to deal with the issues of too many people and finite resources.
Firstly, it is irrefutable that poverty, along with hunger, are two of the most critical consequences of overcrowding. In many developing countries, where family planning schemes are lacking, population growth is endemic. For instance, the Indian population grows by around 15 million each year, and has overtaken the growth in the Chinese population by a factor of four. However, these are not just some Third-World problems, but difficulties the whole world, as a community, needs to address.
Secondly we can also point to the serious environmental problems created by this phenomenal population growth. We can point to issues such as increased pollution levels which can be attributed to the overuse of carbon fuels and the large amounts of plastics and rubbish generated in such societies. Furthermore, in the effort to feed the hosts of people on this planet, the focus on factory and intensive farming methods is being cited as a key factor in climate change.
In conclusion, I strongly agree that overpopulation has placed an enormous burden on each citizen and the environment, and this aspect is at the root of many of the world’s problems
The rise of human population, an ongoing global concern, is caused by technological advancements since the Industrial Revolution. While this issue is widely considered as one of the most serious problems, in my opinion, the greatest threat to humanity in the 21st century is climate change.
A rapid growth of human population usually coincides with a technological outbreak. Since the Industrial Revolution, human society has gradually shifted from craft production to machines. Thus, for the first time, mass production is available. This situation increases life expectancy of the majority of the people by providing stable food supplies and medical treatments. Consequently, world population has risen; now it has passed the point of 7.5 billion.
The consequences of an increasing population are detrimental. Overpopulation is the reason for overconsumption, which results in resource depletion and environmental degradation. Unemployment is also seen in densely populated areas.
However, climate change, instead of overpopulation, is the biggest global challenge nowadays. Many developed nations have low birth rates due to high level of education; therefore, overpopulation does not happen on a global scale. By contrast, climate change has been affecting both of ecosystems and social systems around the world. From an environmental perspective, climate change creates more extreme weather conditions, thus hampering the agricultural industry. Furthermore, global warming leads to sea level rises, which forces the people in coastal regions to migrate. This situation causes many social issues, such as overpopulation or criminality.
To conclude, the recent rise of world population happens due to technological advancements. Nevertheless, despite human overpopulation and its negative effects, what should be addressed first and foremost is climate change.
