Most modern plastics are derived from petroleum.
This involves many costs to the environment.
Extracting the oil/gas/coal causes pollution and affects the landscape. Transporting the oil is risky. Failures in the system results in expensive and often inadequate clean -up.
In 2013, a freight train carrying oil de-railed and exploded in Lac Megantic, Que.
The resulting fire resulted in 47 deaths.
Current oil spill clean-up technology is not efficient..
Modern technology is still not able to prevent spills and their consequences are poorly understood.
