1、題目大意

世界上的大多數問題都是由人口過剩引起的。你是否同意？

2、思路解析

這是一道觀點類大作文，聊得是人口過剩引發的問題。題目閱讀上不難，審題時需要注意觀點要圍繞“over-population”，同意需要說明人口過多如何引發問題，反對的話需要說明同樣的問題實際是由哪些因素引發了。下麵，月半鴨和大家一起來看下具體(ti) 觀點。

首先來看讚同的角度，有兩(liang) 方麵。

一方麵隨著人口的增加，人們(men) 資源的需求也在增加。例如，人口增長導致了對食物、水、土地和能源的需求增加，這可能導致資源短缺，甚至可能引發衝(chong) 突和戰爭(zheng) 。同時，獲取食物和能源過程中的過量開采和捕撈會(hui) 對自然環境和生物多樣性造成破壞，大量工業(ye) 品的生產(chan) 和廢棄還會(hui) 對空氣、水和土地造成汙染。

另一方麵過度人口可能導致社會(hui) 問題，如失業(ye) 、貧困和不平等。隨著人口的增加，就業(ye) 機會(hui) 可能變得更加稀缺，而且可能會(hui) 有更多的人陷入貧困。

反對角度來看，同樣可以有兩(liang) 方麵。

一是諸如資源不足、貧富差距等問題可能並不是因為(wei) 人口過多，而是資源分配不均。就以糧食問題為(wei) 例，世界上或許有足夠的食物供應，但是由於(yu) 物流、國際政策及資本壟斷等原因，導致很多人無法獲得足夠的食物。

二是有些問題無法解決(jue) 可能因為(wei) 個(ge) 人意識不到位以及政策錯誤。比如人們(men) 對於(yu) 環境保護的意識不足，或是政府為(wei) 了經濟發展忽視了環境保護，那麽(me) 即使人口減少，環境問題也可能仍然存在。

3、提綱

4、高分範文示例

Many individuals believe that overpopulation is to blame for most of the world's problems, which have worsened dramatically over the last several decades as the global population has skyrocketed. I agree with this point of view and believe that a densely populated society is destructive to both human life and the environment.

There is no doubt that overcrowding exerts several negative repercussions on human life. In terms of living conditions, overcrowding may make life less enjoyable. There will be a housing scarcity if economic growth and productivity fall behind population expansion. As a result, there would be congested housing and even homeless individuals living on the streets. The same rule applies to food and other necessary good shortages caused by overpopulation. In locations with low productivity and a poor climate, however, this food demand can barely be met. In addition, these food shortages result in higher food prices, which exacerbates the plight of individuals who reside in impoverished regions.

In addition to the aforementioned practical challenges, overcrowding also causes a number of environmental issues. In the first place, population strains the planet's nonrenewable natural resources. As fuels are required for the majority of transportation, a growing population may also raise the demand for fossil fuels, hence accelerating the depletion of natural resources and causing a potential energy crisis. Secondly, overpopulation causes global warming by emitting additional carbon dioxide. Humans are not the only source of rising carbon dioxide levels; livestock and transportation emissions also have an impact. In addition, more trees, which were intended to convert exhaled carbon dioxide into oxygen, are being cut down to suit the rising demands of human activities, leaving the exhaled carbon dioxide unabsorbed.

In conclusion, I feel that the dilemma of overpopulation is accountable for the majority of the world's challenges and should be a top priority for many national authorities.
