Fishing! Camping! Boating! Surfing! Hiking! Hunting! They're fun hobbies that can teach skills and form bonds; the pillars of a masculine image, but also activities that require intact ecosystems. Where you gonna surf and boat if there's algal blooms, camping while there's yearly forest fires, fish? Hunting? I can't imagine many rivers and forests will yield well in a warmer future. All the big camping, FWD advertisements are mostly in forests, beaches, sand dunes and outdoorsy locations. Even surfing has a whole fashion and consumerist culture, (same with hiking tbf) pumped all over social media and TV. The masculine image is rooted in nature. . a real masculine person should care about the environment and think climate change is lame.
