What was the theme of 2019 World Environment day?

  • Beat air pollution
  • Chosen by this year’s host, China, this year’s topic invites us all to consider how we can change our everyday lives to reduce the amount of air pollution we produce, and thwart its contribution to global warming and its effects on our own health.

What Causes Air Pollution?

  • Understanding the different types of pollution, and how it affects our health and environment will help us take steps towards improving the air around us.
  • Often you can’t even see it, but air pollution is everywhere. We can’t stop breathing, but we can do something about the quality of our air.
  • Nine out of ten people worldwide are exposed to levels of air pollutants that exceed safe levels set by the World Health Organization. There is little doubt – we are faced with an urgent task.

Causes of Air pollution:

  • Household – The main source of household air pollution is the indoor burning of fossil fuels, wood and other biomass-based fuels to cook, heat and light homes. Around 3.8 million premature deaths are caused by indoor air pollution each year, the vast majority of them in the developing world.
  • Industry – In many countries, energy production is a leading source of air pollution. Coal-burning power plants are a major contributor, while diesel generators are a growing concern in off-grid areas.
  • Transport – The global transport sector accounts for almost one-quarter of energy-related carbon dioxide emissions and this proportion is rising. Transport emissions have been linked to nearly 400,000 premature deaths.
  • Agriculture – There are two major sources of air pollution from agriculture: livestock, which produces methane and ammonia, and the burning of agricultural waste. Around 24 percent of all greenhouse gases emitted worldwide come agriculture, forestry and other land-use.
  • Waste – Open waste burning and organic waste in landfills release harmful dioxins, furans, methane, and black carbon into the atmosphere. Globally, an estimated 40 percent of waste is openly burned.
  • Other sources – Not all air pollution comes from human activity. Volcanic eruptions, dust storms and other natural processes also cause problems. Sand and dust storms are particularly concerning.

 

The Environment and the Sustainable Development Goals

  • The 2030 Agenda for Sustainable Development states our resolve “to ensure the lasting protection of the planet and its natural resources”. In particular, Goals 14 and 15 focus on protecting under water and on land ecosystems, as well as on sustainably using marine and terrestrial resources.

  • Plastic packaging accounts for 50 per cent of plastic waste.
