I dont think the fishing is better than ever is even close to being correct. Our oceans, rivers, lakes are completely overfished right now. Its crazy how many restrictions are being put on individual fisherman, and some of the commercial guys. I spoke with a fishing guide in southern oregon a couple years back. He does both river and ocean trips. He said that if you banned commercial fishing completely for 5 years, and then kept the current limits on the individuals, it would still take several years for the the fish levels to be back up to what they were 25 years ago. Sushi, and "healthy" eating has driven the fish marketbover the edge. Its crazy.
All the other stuff in that article is more than likely quite overblown.
Recycle, pick up trash when you see it, and try and keep our overall mess to a minimum. Thats all we can really control at this point.
