The not efficent cars contaminate the world with polution. Taxis and small buses are not usefull because they can cary a small quantity of people. Old buses make lot of polution thats why we shouldnt ride them. Very luxy cars can only cary 2 people and the norrmal ones 5, 7, or more. Cars and buses are ones of the more masive producers of polution that make global warming.

for exmaple in Bogota they are buses like this: 3063 from the year 1983 and back. 558 from the year 1984-1989. 2958 from the year 1989-1993. 4309 from the year 1994-2000. 7685 from the year 2001 and more.

Can you believe that? they are 7685 from the year 2001 or more. Also can you believe that they are still many buses from the year 1983 and back.

AND REMEMBER THIS BUSES ARE JUST IN BOGOTA DO YOU IMAGINE IN HALL COLOMBIA ?
