I'd have to disagree with that. There are lots of people who care and have tried to be good stewards to the public. The problem is that you also have corporations with major amounts of cash and influence that actively discredit anyone who speaks out. These are facts.
For example, whether or not GMO issues are horseshit or not doesn't matter when anyone who speaks out is given a gag order or when we find leaked documents showing that companies know of damage and our systems are so fucked we aren't even allowed to ask about it without getting sued into oblivion.
People care, but caring isn't enough anymore.
