Environmental Impact of our Hobby.

[Aquattro]

I go out for hours and this is it?

I guess this spawns from a comment once said to me, that a real reefer would care about the impact to the local landfill in relation to discarding cheap equipment.
My thought is this. A real reef lover, someone that truly loved fish and corals and that comes with it, would leave these things in the ocean.
Are we not somewhat selfish in our pursuit? How many fish die for each one we keep? I mean from capture to us having a fish 6 months later, how many never made it? How many corals die during harvest, transport, poor handling before we get the "hang of it"? How many reefs are blown with cyanide to provide us a single fish?
What about resources to manufacture the systems we use? The salt we mix? The water we waste?
Sure, we all take steps to minimize all this, but still. Isn't there some impact, and really, no return for the environment?

Just food for thought..
