He looks pretty scrawny for a nine year old. Probably not getting enough GMO foods.

I hate and routinely protest the GMO food phenomenon, not because they're unhealthy, but because they're entirely untested in the longterm, but still available for nearly-literally the entirety of the North American public in unmarked products.
Despite that, there are very, very few people who have such a realistic, objective grasp of world events, and the experience to analytically base their judgement and actions on, that I can't really take a video like this seriously. Ultimately this is no different than the 9 year old religious-born professing the superiority of 'god', or the 9 year old partisan politician speaking on the benefits of their specific political party.
Ultimately, and sadly, this is just an example that a specific kind of education can cause any good student to regurgitate what they've learned. The kid doesn't strike me as having a particularly advanced grasp of the topic for his age. He's just regurgitating what he's been told, which is as much of a problem with people as the government and corporate environment we've created.
You will never change society, business or politics until you learn to teach people to learn to teach. Education is the only way out of this mess.

Why is it that the author of that speech sends out a kid to deliver it to the public? Doesn't that person know that this is a cheap, disingenuous tactic that only weakens the message?

Hate... Hate... Hate... THIS.

I'll be honest I didn't make it very far, and i might agree with a lot of what the little guy has to say. The problem is i don't believe for a second it's him saying it. Overly scripted, rehearsed and exploitative.

I'm with @artician...I'm not against GMO's because they're 'bad', I'm against them because they're untested, unlabeled, and are quickly replacing tested 'natural' foods and crops across the board and around the world. It's terribly irresponsible science to replace so much of our food crops with untested science experiments, knowing full well there will be side effects we didn't foresee and likely can't accept.
I would also agree that the child SEEMS to be simply repeating a speech he memorized, written by someone else much older. I HATE that kind of BS, more so when it's done this way, pretending the child is speaking and not regurgitating. I may agree with much of what he said, but much of his message is lost to me because of the attempted 'tug at my heart strings'.

Yeah, but look at him when he walks off the stage, he doesn't seem too proud to me. He seem pretty sincere.

I'm guessing this kid came up with this by himself after a whole lot of analysis and critical thinking.

Or he was used as a prop to (unintentionally or otherwise) undermine your own movement. I'm gonna petition the EU to have this erased from the internet.
