--I thought its was because we either can't afford powerboats or were
too cheap to buy one.--

Well, originally you may buy it because of that. But then you say,
"Gee, I'm also doing the right thing!" (I hate motorboats, but would
love to have a sailboat --and my canoe/kayak!)

Which brings us to the issue, ARE THE POOR BETTER ENVIRONMENTALISTS?
Well, some lions --a tiny minority-- got money and also have a small
footprint. Here for example is Paul Newman and his daughter. I was
reading last night how she defended having a Porsche, but only using
it once a week and then use public transportation the rest of the
week. Something understandable, no?

The very poor though may not have the inspiration to own a small
watercraft or bike for lack of education, and some, given the chance,
would love to become lions.

Just some thoughts about the jungle.
