高分写作示范

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.
