That begs the question- change the world to what, exactly?
It's not exactly a bed of roses for the hundreds/ ? thousands of species we have made extinct, is it?
If we are to believe your side of the debate, it has taken since the industrial revolution to change the world to what it is now , a period of about 300 years, and you claim it is possible to reverse it, to presumably 300 years ago, in a decade or so using "science" which created the problem in the first place.
I am unable to give credence to that theory, regardless of how many "experts" pontificate about it.
