I have used examples concerning saltwater species, but equally important issues confront the freshwater angler.
Pollution, and particularly acid rain, have destroyed thousands of lakes and rivers that once provided good fishing. There are no fences in air space that can keep out the clouds of pollution, so we’re all vulnerable.
We think of the Scandinavian countries in terms of pristine environments, mountain lakes and winding, pastoral streams, but they have suffered massive losses. Norway, as an example, has lost total fish stocks in approximately 5,000 lakes! More than a third of her rivers have critical loads of acid rain! And more than 90 percent of the acid rain that falls over Norway originates in other countries.
