If public transportation in Tijuana were decent, air quality wouldn't be poor and wouldn't affect health, said the leader of the Green Nation civil association.
Octavio López criticized the fact that the price and overcrowding of public transportation means people choose to travel around the city in private cars, causing the generation and spread of smog.

He proposed the creation of better passenger vehicles and more programs to make the service free, such as the Purple Route used by women. He also proposed the creation of safe lanes for bicycles, which would also promote physical activity and reduce obesity rates.
Furthermore, López said that given the high pollution levels, the creation of vehicle inspection centers is necessary, as implementing the No Circula program is not a complete solution for restoring the environment. And if implemented in Tijuana, it would encourage families to own more than two cars.
