Washington’s native people produced a minimal impact on their environment in the following ways:
- Built fish traps across rivers: This traditional method allows for sustainable fishing without significantly altering the ecosystem.
- Harvested bark from trees: Gathering bark for making baskets, clothing, and other items can be done sustainably without causing long-term harm to the trees.
The other options listed typically involve significant alterations to the environment, which would not be characterized as having a minimal impact.
