Answer:
the Lewis and Clark expedition!
In 1804, Sacagawea was living among the Mandan and Hidatsa, near present day Bismarck, North Dakota. Approximately four years earlier, a Hidatsa raiding party had taken Sacagawea from her home in Idaho and from her people, the Lemhi Shoshone. Living among the Mandan and Hidatsa, Sacagawea married French trader Toussaint Charbonneau. In February of 1805, she gave birth to a baby boy, her first child. Captain Lewis recorded the event in his journal: “about five o’clock this evening one of the wives of Charbono was delivered of a fine boy.” I think a positive effect on the environment is when they discovered great places! I don't think there is a negative effect in this situation as far as I know!
