Externalities - The Human Cost of Marine and Traffic Pollution
7th January 2022
Many teachers covering the negative externalities from pollution might want to use these short video and audio clips as part of their course.
This Economist clip looks at the most extreme forms of marine pollution which result in 'dead zones' - with parts of the ocean starved of oxygen. This phenomenon can kill almost all marine life - in this case, in Turkey - and is the result of the negative externalities often associated with sewage and the overuse of fertiliser and pesticides in agriculture.
In this audio clip, we find that traffic pollution is linked to one in 12 child asthma cases. According to the main author of the report, "Air pollution is a leading cause of disability and death all over the world, and needs to be central on the public health agenda."
