When I wander out into the world--particularly when I'm hiking or on a road trip exploring beautiful natural places--I make a point of capturing shots of various types of pollution. I originally started doing this with the intention of selling the shots through my microstock agencies, because this is a hot topic across the world. Those agencies pay so little however, that I haven't uploaded many of them to those libraries. Instead, I'll start sharing them here and licensing them directly.
This is just a tiny sampling for now. These two images show tobacco and cigarette trash laying on a stone wall on the Oregon coast. The gorgeous ocean waves in the background play a stark contrast to the ugly trash in focus.
