Answer:
A. Deforestation
Step-by-step explanation:
This is one negative environmental effect that is not associated with cars. Roadside litter is associated with cars because people who are in a car often toss trash on their way, which lines the roads with litter and debris. Toxic river pollution is also an effect linked with cars because the improper disposal of cars (as well as used oil, filters and vehicle fluids) can pollute rivers and soil.
