I agree with the OP (slightly) in the sense that there are too many people shoving it down your throat everywhere you turn. The truth about it all is that most companies will claim to go green or sell green because it is the current trend. Of course, as technology improves, cheapens, and the public gains more knowledge of the matters, these companies that claim their "green-ness" will be questioned. Eventually there will be restrictions placed on companies and their abilities to claim being green.
Anyway, there are so many different arguments going on here that it's difficult to manage them all. Green technology is not always as green as they state because you have to look at the overall footprint of it all. Using an electric car is great because it is 0 emissions, however, how much carbon was produced generating that electric you're taking from the outlet? If it's a simple matter of using chemicals vs. not using chemicals, I say use less chemicals. But, many people buy shit that's got a green label because it has a label rather than researching to figure out whether it's truly the best option to go with.
For example, they want to use corn to produce the next fuel for our vehicles. However, think about how many edible crops will be wasted, how much additional farmland will be used, how many chemicals, tractors, buildings, plants, etc will be required. It's a lot to consider.
So, my outlook is that I will recycle where I can, turn off lights, open windows, use less power, etc etc where I can and where it's worth it. Not to my wallet (well, sometimes to my wallet) but worth it in the sense that it actually does something positive.
For the food argument, I see nothing wrong with unnatural and unhealthy foods. It's bad for you in excess, which seems to be the key theme through it all. Moderation! I love foods of all type. I'd rather die at 80 and enjoy my life than 100 and eat Kale every day. I luck out in that I like veggies and fruits anyway. However, I will not cut beef out! I need a steak once in a while. That plus activity and I'm in great shape. Fat Americans, as well as fat people around the world, are usually a result of inactivity and poor diets. Just because someone eats a shitty diet doesn't mean they're fat. I know plenty of skinny people who eat like crap. I know my parents grew up with all types of shitty foods, but they also didn't sit in front of the tv playing video games like the majority of children do.
I'm a bigger proponent of exercise than diet anyway. They are both important, but exercise is on a whole different level. Limit video games and make your kids play outside. Shit, I used to play in the woods, fall and get cuts and bruises all of the time, and ride my bike for hours with friends.
