Well il try my best (Apologize my english, its 4 am here)
I think the first thing that we would need would be a efficient but still environmentally conscious way to get energy (Nuclear Fusion/Efficient Fuel Cells/Solar Panels/Maybe some day Antimatter Technology etc), that would be the first step.
The next step would be to find something to replace the normal fuel, hybrid engines are the first step for it but lets face it they are not really efficient.
I think that earth has already taken significant damage and that we need to do something right now, but the problem is that we havent got the technology for it yet.
I personally think that humans are like a dissease for this planet, were building citys, develop our technology and destroying everything thats in our path.
I dont think that earth is ever going to recover (Atleast not aslong as we humans exist), and the fact is, we humans are getting more and more and we need place to live, means we have to build citys, means we have to get resources and that means that we have to destroy the planet further.
The whole world, not just some single countrys, really the whole world needs to work together, develop our technology and try to stop the pollution.
But the probably most important thing would be to change the peoples minds, if everyone in the whole world would start to recycle, use less resources could we stop the pollution, im not saying that we can make the planet *healthy* again but we can atleast keep it on the level it is right now until weve got the technology to repair the planet.
Also some people think about moving to another planet, but i think thats just rediciolous, if we cant stop all the shit here (Sorry for the language) than theres no point in moving it to another planet.
That are my thoughts, i will actually think about this and do some research and answer you guys tommorow since i havent got shool tommorow, sorry i know u wanted that i go into detail but im simply too tired at the moment (Well i will help a friend of mine to paint his apartments but afterwards will i answer)

@Dixter
Well first of all, i really really laughed about that video, thanks for that (Especially when the questions *What religion have buddhist monks*, *Whats the religion of the isreali* and *How many sides has a triangle*.
To your question, it has alot to do with the countrys educational system, lets take austria as an example, i went to a crappy shool when i was younger, nearly noone has made it trough the third class, alot of foreigners that didnt speak german, the teachers were also not really motivated.
Okay didnt matter, since i was 8 have teachers been telling my mother how smart i was for my age, knowing stuff that not even kids that were 3-4 years older than me knew, than i went to a shool called *Europaschule*, it was a excellent shool, motivated teachers, nice classrooms and the newest technology (We even had our own computer in our class), ive learned alot there and i found some teachers i really really liked (Like my old math teacher, he never got angry and he explained everything, no matter how long it took for someone to understand) and he was really so excited when he was talking about mathematic and physics, he was my idol.
So im now 18 years old, i finished the 3 years of my apprenticeship (Atleast thats how its called here in austria) and im officially a salesman? (Well dunno how its called, its called *Einzelhandelskaufmann* here in austria) and now am i going to a HTL (Higher Technical Institut) [Electrical Engineering] and that even for free!
After ive finished this shool have i got my masters degree and i can go to a university.
Here can u see what it exactly is, also when the title seems german, its in english
Höhere Technische Lehranstalt - Wikipedia, the free encyclopedia
So yeah, the shool system is very very important but the people also actually have to have the will to learn.
Most people think they know whats going on when they watch the news @ the TV now and than but thats just how it is.

@ Everyone, i like this serious discussion and i think that one of you guys should make a thread so we can actually share our opinions about everything, this is by far more interesting that these other forum games.
