I enjoy camping/fishing and am relatively conscious of my actions. I was very frustrated with all the lead and plastic used in fishing. I have been following closely over the last few years and have finally started a company which only sells environmentally friendly (or at least more friendly than what's available) fishing tackle, Green Tackle (can't post the link but it's greentackle dot com). This biodegradable fishing line, Bioline, is LONG overdue and I was so excited when it finally was launched that it contributed to my finally starting my store. There was another biodegradable line a few years back but it never took off or got US distribution.
I think the time has come. We're seeing more and more companies within the industry embracing these alternatives and promoting environmental stewardship. Big names like Berkley Fishing and South Bend have introduced biodegradable products to replace the plastic and lead the traditional tackle uses.
I fish, and when I go out, it seems like the number of people picking up other people's old line and trash outnumber those who are throwing it around. We're ready for it... we just need to spread the word. If you know somebody who likes to head out to the lake/river/beach during the summer to throw out a line, let them know there are biodegradable alternatives.
