Good point about the litter. I'll tolerate a few clouds of smoke about, but the littering does piss me off. I am a bit down on recreational fishers for the same reason.
Dumping a butt that is still smoldering is IMHO criminal, at least in fire-prone areas like Australia.

Yeah...that's bad on so many levels. Every time we go for a walk on the beach we take a shopping bag with us, and it's rare for it not to be at least half full by the time we get back.

And let's not even get started on the damage plastic bags etc can do to turtles and dugongs even!

...or the plastic six-pack holders.

Yeah...all you've got to do is watch 'surfs up' to know how bad they can be!

Eh. Campus wide is a bit over the top. But having specific assigned areas to smoke is a good thing. Most military bases have them and have had them for a good 10 years and it has worked. It really helps with the litter of butts that is a product of the smoking habit.

I smoke in my truck and I always have a butt bucket handy...I do not flick. Yeah, I'll let ash out but that's not going to hurt anything. I yell at my students if they don't use the bucket too. There are many fire prone areas in the USA also, like Oklahoma, New Mexico and Arizona and Texas...basically the entire southwest.

Although if someone wants to burn down all of Los Angeles, I won't stop you!
