题目大意：
有观点称保护环境的关键是当代人愿意为了下一代而牺牲生活质量。同意反对？

思路解析：
这是一道观点类考题，聊得是解决环境问题的手段。这道题目中的关键词是the key. Collins词典对key的解释是“The key person or thing in a group is the most important one.”。建议取反对的立场，并在论证中提出别的办法即可。下面，就和大家一起来看下具体观点。
首先，现在生活的便利主要建立在工业品的运用上，包括塑料袋等生活用品、电视冰箱等家电以及汽车飞机等交通工具等等，这些都会给生活带来便捷。而不可否认的是，这些产品在使用的过程中都会造成环境污染，塑料袋难以被降解随意丢弃会污染土地和水资源，汽车、飞机等交通工具会产生废气排放造成空气污染。因此，现在减少使用这些产品，确实有助于环保，为后代保留一个更好的生活环境。
但是，想要达到环保的目的还有许多更好的办法，并不是一定要牺牲现在的生活便利。一方面可以发展更多清洁能源以及寻找更环保的替代品，比如用电动汽车来替代燃油车、用高分子材料制作可降解塑料来替代传统不可降解的塑料等等，这些方式既可以保持人们生活的便利又可以起到环保的作用。另一方面，工业排放、城市化扩张等都会造成环境问题，这些单单让人们降低生活便利并没有作用，而是需要政府出台相应政策，针对工业排放的问题可以要求工厂采用新技术有效处理废气和污水，针对城市扩张破坏大自然的问题可以建立专门的自然栖息地来保护环境及当地生物。

范文示例：
There is an assumption that the important solution to protect the environment in the long-term perspective should be at the cost of living standards of current generation. Personally, I would say it is an oversimplified conclusion due to the irrelevant connection between environmental disruption and our lifestyle.  
Indeed, it is not difficult to understand why a change in our lifestyle is deemed pivotal to the environmental conservation. Those who think in this way opt to attribute the majority of ecological problems to our preference for convenience, whether it be our reliance on disposable products such as plastic bags, prepared food that contains lots of packaging, or overuse of private cars; all these are recognized as major culprits of pollution. In this respect, some environmentalists conclude that curbing our preference for a convenient life is essential to mitigate pollution on the planet. For example, the less use of private cars could fundamentally reduce greenhouse gas emissions.        
Plausible though the logic seems, it does not necessarily mean the better environment hinges exclusively on people living a less comfortable life. The problem with the above reasoning is that the conclusion is based on the overgeneralization of the reason – the so-called ‘environmental problems’ are not the simple result of our preference for convenient life; rather, other factors also contribute to the tricky condition. Examples can be seen in the global warming caused by industrial discharge, or the shrinkage of the habitat of flora and fauna due to the relentless urbanization. In response to these, a change in lifestyle of the populace doesn’t seem to be the key panacea, whereas the other options might be more effective. A more practical approach is for the government to subsidize industries in using greener energy (e.g. solar and wind power), or to legislate against city expansion plan that encroaches on natural habitats. 
It is my conclusion, therefore, the environmental preservation is not correlated solely with our way of living, while it is a trick condition that needs multiple measures.
