ദിവസേന അന്തരീക്ഷത്തിലെത്തിച്ചേരുന്ന കാർബൺ ഡൈഓക്സൈഡ്, മീഥേൻ, നൈട്രസ് ഓക്സൈഡ്, ക്ലോറോ ഫ്ലൂറോ കാർബണുകൾ എന്നീ വാതകങ്ങളുടെ അളവ് കൂടിക്കൊണ്ടിരിക്കുന്നു. ഇവ ഓസോൺ പാളികളുടെ തകർച്ചയ്ക്കു കാരണമാകുകയും തന്മൂലം ആഗോളതാപനം ഉണ്ടാകുകയും ചെയ്യുന്നു. മരങ്ങളും കാടുകളും സംരക്ഷിക്കുക, വനപ്രദേശങ്ങൾ വിസ്തൃതമാക്കാൻ ശ്രമിക്കുക, അതുവഴി ആഗോള പാർസ്ഥിതിക സന്തുലനവും കാലാവസ്ഥാ സുസ്ഥിരതയും ഉറപ്പാക്കുക എന്നതാണ് പരിസ്ഥിതി ദിനാചരണത്തിന്റെ ലക്ഷ്യം. ‘കാർബൺ ന്യൂട്രാലിറ്റി’ കൈവരിക്കുക വഴി ഓസോൺ വിള്ളലിനു കാരണമാവുകയും ആഗോളതാപനം ഉണ്ടാക്കുകയും ചെയ്യുന്ന ഗ്രീൻ ഹൌസ് വാതകങ്ങൾ പരമാവധി കുറയ്ക്കാനുള്ള ശേഷി കൈവരിക്കുകയുമാണ് ഉദ്ദേശിക്കുന്നത്.
2019 CELEBRATIONS
World Environment Day 2019 will be hosted by China, with a theme of "Air Pollution". We can't stop breathing, but we can do something about the quality of air that we breathe.
Approximately 7 million people worldwide die prematurely each year from air pollution, with about 4 million of these deaths occurring in Asia-Pacific. World Environment Day 2019 will urge governments, industry, communities, and individuals to come together to explore renewable energy and green technologies, and improve air quality in cities and regions across the world.
Air Pollution facts:
- 92 per cent of people worldwide do not breathe clean air
- Air pollution cost pts the global economy $5 trillion every year in welfare costs
- Ground-level ozone pollution is expected to reduce staple crop yields by 26 per cent by 2030
“Beat Air Pollution”
Each World Environment Day is organized around a theme that focuses attention on a particularly pressing environmental concern. The theme for 2019, “Beat Air Pollution,” is a call to action call to combat this global crisis. 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.
- 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.
