用英语翻译一下 下面这段文字 ,希望人工翻译下 不要用机器翻

任何极限运动都可以说是一种科学实验！

他们都是在挑战人类生存的极限，这对于人类的未来
发展与社会环境的改善都有帮助。

可能，现在你不能看到他的意义，似乎这只是个人的
理想实践，其实，他们所能完成的事例，恰恰有可能
帮助人类探索更加深奥的知识！

参加极限运动的人，不但具有探索精神，也是人类发展
的先行者，就像登月一样，同样花了巨资，好像也没什
么利润，风险又很大，可是没有一个地球人觉得这是浪
费钱！

极限运动其实就是一种人类的探索运动，人类渴望了解
自身、地球、宇宙的更多知识，以用来开发出人类在极
端环境下的生存方法！！！

但是现在极限运动的人往往都是个人行为，所以他们的体
育与探索精神就更应该值得我们尊重，他们用自己的精
力与金钱去探索和考验自身的体能，很多人把自己得到
的知识无私的奉献给了没有机会去体验的人，他们大多
数人的行为应该是值得肯定的！

Answer 1

Every extreme sport is a scientific experiment.

They are challenging the limits of human survival, and beneficient to human future development and social environment.

Perhaps, you can't make any sense from it, it seems like only just a personal achievement, however, what they have achieved, possibly helps us to explore more abstruse knowledge!

Those who participate in extreme sports, not only have the spirit of exploration, are also the pioneers in human developments, like landing on the moon, huge amount of money was spent, almost no profits in return, and its great risk, but not a single person on earth thinks it was a waste of money!

Extreme sport is actually a human exploring sports, human desire to understand themselves, the Earth, the universe, to find a way for human to survive in extreme enviroment!!!

But then extreme sport participants are currently individual, their spirits of sport and exploration should be worthy more of our respect, they relied on their own money and vigor to explore and test their stamina, many people share their knowledge selflessly for those who have no chance to experience, most of what they do are definitely impressive!
