I think after you’ve watched mainstream “news” for a while, you can kind of read between the lines. I like NPR, PBS, and BBC, too, but even NPR is sometimes not totally clean. If it is an issue I am particularly passionate about, I will do independent background research. This can mean digging up things around the internet, talking with knowledgeable local experts, finding scientific journal articles….basically getting to the source of the story, which usually yields several other leads. I have even had email conversations with journalists/reporters before about their stories. The fact is though no one knows all the details of everything that’s happening. I suggest reading It’s Our Turn to Eat by Michela Wrong. I think you’ll find it interesting.
