Water pollution, on the other hand, impacts the marine ecosystem contaminating our oceans. This, in turn, affects our food chain, exposing our fish and seafood to toxins like lead, mercury, cadmium. When these toxic components sneak into our body, we become vulnerable to various disorders. These include neurological damage, multiple sclerosis, kidney failure, respiratory disease, gastro-intestinal disorders and cancer, among others.

So, we need to protect the environment to save our own lives. World Environment Day is celebrated to send this message across. Every year, one country hosts the official celebration of this day. The official celebration highlights some specific problems and urges the global leaders to take action accordingly. This year’s host is China.

History

World Environment Day was established by the United Nations General Assembly in 1972 during the conference of Human Environment held in Stockholm (Sweden). This also lead to the formation of the United Nations Environment Programme (UNEP). Two years later, in 1974 the first World Environment Day was celebrated with the theme ‘Only One Earth’. Since 1974, WED has helped the UNEP to raise awareness on issues like toxic chemicals, depletion of the ozone layer, global warming, etc.

Why we need to beat air pollution

As already mentioned, the theme of the World Environment Day 2019 is Beat Air Contamination of the air is rising alarmingly. According to the World Health Organization (WHO), nine out of 10 people breathe polluted air worldwide. We need to put a brake to the progression of this increasing global problem.

Air pollution occurs when harmful gases, chemicals, etc. are introduced into the atmosphere. On this World Environment Day, let’s pledge to take constructive actions against air pollution.

Sources of air pollution

There are various sources of air pollution. Here, we take a look at the most prominent ones.

Household:

The main household source of air pollution is the burning of fossil fuels, wood and other materials used to cook.

Industries:

Industries increase the emission of harmful gases in the atmosphere in the form of smoke. The chemicals of those toxic gases are harmful to one’s health.

Vehicles:

Cars, bikes, trucks, buses, and almost all modes of transport run on fuels. With the increase in population, the number of vehicles on the road has also increased. This leads to carbon dioxide emission, another gas that harms human health in more ways than one.

Other sources:

Apart from man-made pollution, there are natural air pollutants too. These are sand storms, volcanic eruptions, etc. However, these are inevitable and cannot be controlled while the other causes of air pollution can be controlled.
