I think it is a great idea to celebrate! I did not realize this, but it certainly shouldn't be thought of with the negative mentality of "much ado about nothing." It is an accomplishment that should be looked at with much praise.
Good, I'm glad I'm not the only one then!
Yes, and we'd better step it up, considering the rate at which we're depleting the Earth's food and energy resources, not to mention that we're using them at a record pace, with more humans eating away at the planet than ever before.
Go humans, go!
