What’s Next in Biodiversity?

extinctionWe are in the middle of a mass extinction event, says Professor of Biology Nina Karnovsky, and, this time, it’s our fault.

“It’s called the Anthropocene Era because it’s being caused by humans,” says Karnovsky, who specializes in the study of seabirds. “The warming of our planet, the destruction of habitat, pollution and other contaminants are causing widespread extinctions. It is really grim. I don’t think I would be able to cope if I didn’t try every day to do something to ameliorate this overwhelming thing that’s happening around us.”

Paying attention is one way to make a difference, says Karnovsky, who assigns her students to keep journals and record their observations.

“It’s extremely important to be a great naturalist and to keep track of what you’re seeing around you, and to notice and document that,” she says. “If you aren’t really noticing the change in the species, then you won’t notice when they’re gone.”

In fact, many species that we didn’t know about are already lost, says Karnovsky. It’s not just about climate change, but habitat destruction, harvesting, oil spills and other things that are causing a “vortex of extinction.” And when a population gets impacted and can’t recover, that affects other species, including humans.

“It’s not esoteric. It’s a social justice issue,” says Karnovsky. “There isn’t enough food to eat because the ice has changed; the marine mammals aren’t coming into the fjords where they used to come and people used to hunt them. So for these communities, this is life or death.”

Compounding the problems in identifying and studying endangered species are cuts to research made by the current administration, making it harder for researchers to keep up sustained studies, where they return to the same locations to test for changes that show a species has become more vulnerable.

For Karnovsky, the warnings are clear and call for some big decisions about what direction we’re going. “We need to tell our leaders, and it has to be a multi-pronged approach.” She says. “We have to be active on political fronts, but also in our daily lives.’
