Here's a tip: switch (back!) to a fountain pen.
Why? To answer this, ask yourself this question: during my life, how many cheap plastic pens have I used up and lost, and how many might I run through in the future? If you're like me, many. Now, multiply this number by, um, every man, woman and child above the age of, say, seven -- in the entire U.S. That's a lot of pens. They are not recyclable, the plastic and residual ink (what's in that stuff anyway?) end up polluting the environment.
I made the switch to fountain pens about six years ago when I was considering what little green changes I could make, in addition to the more obvious 'big' changes. So, I bought an inexpensive fountain pen. I've used this same pen for six years now. When the ink runs out, I simply refill it. When the ink bottle runs dry, I chuck the (glass) bottle in the recycling bin and get another one.
It's that simple. No more ball points or rollerball cartridges polluting the environment.
