How can people get interested in the theme of awareness (global problems)?

My question would be what media you would use to investigate global research. The news media is totally bias and is controlled by a higher upper class society of the wealthy. If you use the web then you find both pros and cons of everything. The sad reality is that the social media is controlled and we only hear what those in control want us to hear. Take 911 for example and how the investigation left out so many variables that to this day have caused such huge controversy.
