Air pollution levels in London are dangerously high and currently exceed EU recommended maximum levels. So what are we doing about it?
Scientists have come up with a sticky solution. A layer of a special substance is being spread on roads which will literally stick polluting particles to the ground and stop them recirculation in the air.
High levels of particulate matter in the air are mainly caused by vehicle emissions and can lead to increased respiratory problems such as asthma. It is hoped this new method will reduce air pollution by 10-20%.
Is this just a quick fix solution? What about the alternatives:
changing to alternative fuels (electric, hydrogen, biofuels)
congestion charging and car free town centres;
switching to alternative forms of transport
You could get groups of students to each research one solution and then pitch them to a panel, Dragon’s Den style.
