Environmental aspects

No energy or water consumption like in pools (no heating, no pumps, no chemical treatment).

Lower carbon footprint if you access it without long car trips.

Risk of ecosystem disturbance: swimmers can damage aquatic plants, nesting birds, or fish habitats if not careful.

Community impact

Open-water swimming groups can raise awareness about protecting rivers, lakes, and oceans.

Swimmers can join or support clean-up initiatives and water-quality campaigns.
