Making money also comes with a little problem of the environment. You often make toxic gases. This picture shows the best way to deal with it, release it straight into the atmosphere!
Here we have two straight piped dirty diesels hauling coal to a Canadian steel mill. You can see we have three sources of nasty fumes that release it unfiltered into the air. The exhaust is so strong they all need smoke stacks to make sure it mixes good with clean air. What happens to the pollution after that? Who cares! Everybody got their profit!
