The world is changing...

Hi everyone, today I will talk about the world challenges. If I honest, I really don't know any much about this, only the global warming and the challenges that we have to stop that. I don't want to be a bad person or something because I don't know about this, do you forgive me?
About other topic related to this, it's the globalization and the power that it has to rule the world and consume the people for example. I we think about this, the people spend their money in things that they don't need, they have a consuming impulse that it increases by the money and the markets, I really hate that.
We don't have enough "power" to start a real change I think, If ALL the people around the world don't work together, we don't have a possibility to create a solution to the global problems I guess.
The only thing I can say... I'm a negative person about this, I think the human race will dying because of our conviction, we don't have salvation. Very disturbing no? But, tome it's the cruel truth.
Call me an ignorant or something but to me it's hard to believe in a way to save our lives of the devastation, global warming and things like that.
