then there really is no hope left for this planet. You will need to find another one to live on.
The planet will be just fine. When humans end their lives because of their silly behaviour or an accident then all the remaining organisms will have a lovely time.
Simple life forms, like bacteria will be the last survivors

As for the new world order conspiracy:
I believe that ultimately, the controlling elite always wants the "upper hands" no matter who are they. Every single time if a humanoid gets power in their hands they abuse it like there's no tomorrow. So I don't think there's a specific circle of people in control, rather the ones who get in influential positions.
Also, don't forget that most people doesn't care about things many of us care here. they don't want to think (about anything). :O
