Ever since the dawn of the industrial revolution and the invention of the internal combustion engine in the 19th century, environmental pollution has skyrocketed to unimaginable rates. This is because with the development of the internal combustion engine came a wide range of machinery that has made our lives much easier but has had and is continuing to have detrimental effects on our atmosphere.

The transportation sector was revolutionized by the invention of vehicles and hence road networks. Unfortunately, these road networks are not efficient in taking care of the billions of vehicles that exist on our planet today; the result- unimaginable gridlocks in many major cities like London and New York, leading to more emission of greenhouse gases that ultimately destroys the ozone layer.

Even trains that are being powered by diesel engines or electricity are not free from contributing to this pollution. Aircraft are truly great and it has truly cut travel time to levels unimaginable 130 years ago. However, there has also been ever-increasing pollution from aircraft. Ever since ships stopped using wind has its source of power, it’s a contribution to air pollution has been on a continuous increase. Spillage from oil tankers has also had detrimental effects on both terrestrial and aquatic life.
