Final answer:
The damming of the Colorado River had two main environmental effects: the loss of vegetation in the river's delta and the disruption of the ecosystem and habitats for native species.
Step-by-step explanation:
The damming of the Colorado River has had significant environmental effects. One effect is that the river's delta lost all its vegetation and became desert-like. This is because the damming of the river stopped the water from nourishing the ecosystem of the delta, leading to a loss of habitat for native species and causing dust bowls to become common occurrences in the area.
Another effect of damming the Colorado River is that farmers started using the rivers delta for cultivation purposes, further impacting the ecosystem. Overall, the damming of the Colorado River has led to the loss of vegetation, the disruption of the ecosystem, and the loss of habitats for native species.
