　　雅思大作文7分范文及解析：太空搜索。这道题目宽泛的来说属于太空探索类，讨论如何解决地球人可持续生存的问题。关于这道题，我们可以先承认一下地球上面临的问题，然后再去想如何解决。因为政府的资源是有限的，如果把更多的钱花在研究太空探索上，那么花在解决地球本身的问题上的资源就会削减，可能会得不偿失。所以，这个题目入如果不同意的话，考官是希望看到你的意见的，也就是怎样解决目前人类面临的一些问题，比如说环境污染，资源短缺等等。

　　It is true that, if present trends continue, it will become increasingly difficult to sustain human life on Earth. Therefore, some people argue that in order to tackle this problem, a large amount of money should be spent on space exploration. I believe that expenditure on research for new planets to colonize should be given a low priority, and resources must be used to find other more practical solutions.

　　On the one hand, there are many grave problems faced by our fragile planet. The obvious one is that we have nearly exhausted many natural resources and left a big carbon footprint. The rising consumption of natural resources such as gas, oil and coal has resulted in an enormous amount of carbon emissions being released into the atmosphere, which impairs the air quality and accelerates climate change. It is not uncommon to see that people in many big cities are suffering respiratory diseases; more lands are being shrunk due to the rise of sea levels; and there are frequent heat waves in tropical countries. Apparently, human life is now put in danger.

　　However, I would argue that the search for a new planet on which humans could survive is not an effective method. This is because there is little hope of seeking a planet that has favorable conditions for life while the expenditure can be extremely huge. By contrast, a much better solution would be investing in environmental projects and encourage people to lead a more environmentally friendly lifestyle. For example, green energy should be harnessed and made more available to replace our dependence on fossil fuels, and individuals ought to opt for public transport rather than driving their vehicles. Such actions can cut exhaust emissions and slow down the effects of global warming, making the earth a more desirable place for us all.

　　In conclusion, I consider that the search for new planets on which to settle is a waste of time and resources, and efforts should be concentrated on addressing humanitarian problems occurring on our planet.
