Transportation can be good for the environment in certain circumstances. Public transportation, such as buses and trains, can help reduce the number of cars on the road, leading to lower emissions and less pollution. Additionally, the use of electric or hybrid vehicles can also contribute to a cleaner environment. However, it is important to note that transportation can also have negative impacts on the environment, such as air pollution from vehicles and the destruction of natural habitats for infrastructure development. Overall, the environmental impact of transportation depends on various factors, including the type of transportation used and the efficiency of the system.
