It absolutely is the Age of Food. Not only that, but it's a lot easier to make your own versions of food at home than it used to be. I learned to make waffles and Yorkshire pudding from scratch this year, and I'm even learning to make my own pasta-I'm just not very good at it.
I learned how on the internet. I've also found methods of making my own eggnog, and my own ricotta cheese, I just haven't tried them yet.
And my wife gave me a beer-making kit (Mr. Beer!) for X-mas!
I worry that you're right about things going downhill, Gandalf (overfishing is my biggest concern), but I think for a while atleast, things will keep getting better. We're still in the dawn of the Age, anyway. With the gas prices as volatile as they are, I'm hoping that that will help encourage local food markets in this country. That would be a huge step in the right direction for foodies in the USA. Utah has some of the best produce, and dozens of farms, but the stuff in grocery stores is pathetic. There's really no reason for it.
I'm also growing my own produce in my own garden (with semi-success), and I think that will become more commonplace, too. I'm hoping so, anyway. With people having to leave their homes less and less for work, and with grocery stores and gas becoming more and more expensive, and so much free knowledge available on the internet, it's not unreasonable that more people will get into gardening.
One thing I found on the internet is something called "Terra Preta", which is this incredibly rich, self-sustaining dirt that the Amazonian Indians invented. There's stories about farmers growing crops on this stuff successfully for more than 40 years, without ever having to fertilize. It's pretty amazing, and could be used to feed a lot of people in this country.
