Challenges facing outdoors enthusiasts in many cases are the same challenges, on a grander scale, the world faces.
Example: North American hunters and anglers have led the charge over the past century and a half to conserve the continent's water, habitat and wildlife.
Some of this has occurred for selfish reasons: Sportsmen and women want ample supplies of fish to catch and game to hunt.
But altruism also has been a driver. The natural world is a seductive temptress, and those who spend time in it ultimately succumb to a much broader view of its value, aside from the table fare it might provide.
This appreciation, rekindled every time an angler launches a boat or wades into a river, or when a waterfowler paddles onto a marsh in the still-dark of early morning, or when a big-game hunter draws back a bow or squeezes a trigger, is the bedrock upon which modern conservation was founded.
And continues to thrive.
But perhaps that foundation is giving way to shifting sand.
A major problem is that conservationists never have been able to generate much alarm, or even concern, for the environment, among the wider public.
