In a year like 2020, when everything short-term seems disastrous, it’s hard to focus on long-term change. How everything from ecology’s relationship with the public, to the health of freshwater ecosystems, to just our general sanity seems to be in flux at the moment.
But we’ve been reading about that ad nauseam recently, and I’m sure there will be plenty more to come. So instead, let’s return to an ongoing segment, and have a look at some of the ways that ecology has changed over the last few decades, according to some of the intriguing and prominent researchers we’ve had the chance to speak to over the last few months.
Rivers have played a monumental role in determining where people live. Their importance in providing water, transportation and a raft of other ecosystem services has meant that even today most of the world’s largest cities are situated close to a major source of freshwater, from Sydney to Delhi, Quebec to Karachi.
Yet despite their role in our history, urban rivers today are often facing increasing levels of pollution as a result of human activity. As well as often being a huge tourist drawcard, and an ongoing resource for fishers, joggers and portable BBQ toters, freshwater ecosystems carry a disproportionate number of aquatic species, which makes this trend increasingly worrying.
After meeting at last year’s British Ecological Society Annual Meeting, I got in touch with Dr. Cecilia Medupin, a freshwater ecologist at the University of Manchester. Cecilia works to increase peoples understanding of rivers, including the project Our Rivers, Our City. I asked Cecilia abut our connection with rivers, the challenges they face, and how to inspire research and change in urban rivers.

It is hard to deny that plastics are having a moment – you open Facebook to find videos of turtles floating among plastic bags, Instagram to find every company is proudly getting rid of plastic straws, the news to find out the latest on the Great Pacific garbage patch. Plastics are what colony collapse disorder (aka. where are the bees going?) was a few years ago: the new environmental issue that everyone is talking about.
Now, plastics are certainly an irrefutable problem. We obviously have an unhealthy dependency on plastics that are found in our clothing, food, soaps, and homes. However, there is a question among conservationists and scientists over whether or not it is a good thing that the public conscious seems to become obsessed with a single issue, while others outside the limelight seem to fall away (similar to how in the USA people seem to have forgotten that Flint is STILL without clean water). I want to discuss how the new media landscape propels environmental fads, the good they can do, and the possible problems.
