I try to make all of this manageable for my students in Environmental Science, but they have always left the class stunned at the end of the semester. Every unit, they come up with solutions that previous units should have told them wouldn’t work. It’s difficult to carry so many interlocking things in our head at a time, and it’s natural for us to try to reduce it down to one more important thing that we can deal with. Unfortunately, we never deal with one problem before we move to another.
Save the whales? That used to be a big thing. The whales are not saved, but we’ve moved on. Ozone depletion? I almost never hear about it anymore, except by people who claim it’s over. We did a good job, but there is still a large area of depletion over Antarctica, and it isn’t likely to recover for some time. Litter? Get real. Too much focus on litter during the 70s; much of it was planned as a deliberate distraction that people could wrap their heads around and ignore larger looming problems.
This cannot be solved by focusing on doing just that one thing and then moving on. It’s like a sweater; if you unravel this thread, a lot of threads come out with it, until you are naked and there is a pile of yarn on the floor beside you. Everything (including us) is connected.
Also, something that works in one context won’t work in another. We introduced plants to solve problems a long way from where they grew as natives; gee, that worked out, didn’t it? We cleaned up the air by slurrying it through water; we cleaned the water by evaporating it into the air. When I worked for Air Quality in Oklahoma, the air and water departments were on different floors, but it was a simple one floor flight to visit. No one from air quality ever consulted with water quality; no one from water quality ever consulted with air quality. Everyone is a specialist in one thing, and doesn’t stop to consider how their one thing impacts everything else.
As a result of my rather meandering college and career path, I have education in a lot of diverse areas. It helps me at least a little when I try to pull what appear to be separate ideas but which are connected in strange, overlapping webs of confusion. When I try to explain to my students about the interconnections, I ask them if they think the economy is complicated (a simple flow chart of what companies are owned by one company is enough to elicit a yes). Then I point out that the economy is extremely simple compared to the ecology. It’s sort of like comparing a brick to the Grand Canyon.
