Full Analysis

Imagine your favorite lake slowly turning a darker, tea-like color. That's what's happening in many lakes across North America and Europe. This darker water makes it harder for some fish, like trout and bass, to see and hunt, causing their numbers to drop. But other fish, such as walleye and pike, are better adapted to these conditions and are actually doing quite well. This change is altering which fish dominate our lakes, affecting both the natural environment and recreational fishing.
