In this episode of CORDIScovery, IMPRESSIVE is promoted together with other two EU-funded projects (D-NOSES, APA) offering some answers to questions like the following: In many areas the pandemic has reduced our impact on the natural environment, but what happens when we emerge from the restrictions and fire up our economies once again as is now starting to happen? Will we also be firing up a renewed production of pollution that harms both us and the planet? From oil spills that threaten our seas, to the stinks that ruin our day, pollution touches us at all levels. How can citizen scientists help? What can we do to keep the air around us free of viruses and particulate pollution? Can we really make the polluter pay for oil and waste-water spills in our seas and oceans?
