The United Nations Environment Programme (UNEP) is the leading global environmental authority that sets the global environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the United Nations system, and serves as an authoritative advocate for the global environment.
UNEP’s mission is to provide leadership and encourage partnership in caring for the environment by inspiring, informing, and enabling nations and peoples to improve their quality of life without compromising that of future generations.
The United Nations, considering the fact that the protection and improvement of the human environment is a major issue, which affects the well-being of peoples and economic development throughout the world, designated June 5th as World Environment Day. The celebration of this day provides us with an opportunity to broaden the basis for an enlightened opinion and responsible conduct by individuals, enterprises and communities in preserving and enhancing the environment. Since it began in 1974, it has grown to become a global platform for public outreach that is widely celebrated in more than 100 countries. World Environment Day is the biggest annual event for positive environmental action and takes place every 5 June.
The theme for World Environment Day 2018, hosted by India, was “Beat Plastic Pollution”, which was a call to action for all of us to come together to combat one of the great environmental challenges of our time. The theme invited us all to consider how we can make changes in our everyday lives to reduce the heavy burden of plastic pollution on our natural places, our wildlife – and our own health.
World Environment Day 2019
June 5, 2019 is the World Environment Day. World Environment Day 2019 is being 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.
Here are some startling facts about Air Pollution.
What causes Air Pollution?
Air pollution may seem complex, but we can all do our part to reduce some of it. 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.
How much pollution we breathe in is dependent on many factors, such as access to clean energy for cooking and heating, the time of day and the weather. Rush hour is an obvious source of local pollution, but air pollution can travel long distances, sometimes across continents on international weather patterns.
Nobody is safe from this pollution, which comes from five main human sources. These sources spew out a range of substances including carbon monoxide, carbon dioxide, nitrogen dioxide, nitrogen oxide, ground-level ozone, particulate matter, sulfur dioxide, hydrocarbons, and lead–all of which are harmful to human health.
Air pollution may seem complex, but we can all do our part to reduce some of it. Understanding the different sources of air pollution, and how it affects our health and environment will help us take steps towards improving the air around us. Let us have look at the main sources 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.
Out of 193 countries, 97 countries have increased the percentage of households that have access to cleaner burning fuels to over 85 percent. However, 3 billion people continue to use solid fuels and open fires for cooking, heating, and lighting. The adoption of cleaner, more modern stoves and fuels can reduce the risks of illness and save lives.
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. Industrial processes and solvent use, in the chemical and mining industries, also pollute the air.
Policies and programmes aimed at increasing energy efficiency and production from renewable sources have a direct impact on a country’s air quality. At the moment, 82 countries out of 193 have incentives that promote investment in renewable energy production, cleaner production, energy efficiency and pollution control.
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. Almost half of all deaths by air pollution from transport are caused by diesel emissions, while those living closest to major traffic arteries are up to 12 percent more likely to be diagnosed with dementia.
Reducing vehicle emissions is an important intervention to improve air quality, especially in urban areas. Policies and standards that require the use of cleaner fuels and advanced vehicle emissions standards can reduce vehicle emissions by 90 percent or more.
Agriculture- There are two major sources of air pollution from agriculture: livestock, which produces methane and ammonia, and the burning of agricultural waste. Methane emissions contribute to ground-level ozone, which causes asthma and other respiratory illnesses. Methane is also a more potent global warming gas than carbon dioxide – its impact is 34 times greater over a 100-year period. Around 24 percent of all greenhouse gases emitted worldwide come agriculture, forestry and other land-use.
There are many ways to reduce air pollution from this source. People can move to a plant-based diet and/or reduce food waste, while farmers can reduce methane from livestock by optimizing feed digestibility and improving grazing and grassland management.
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. The problem is most severe in urbanizing regions and developing countries. Open burning of agricultural and municipal waste is practiced in 166 out of 193 countries.
Improving the collection, separation, and disposal of solid waste reduces the amount of waste that is burned or landfilled. Separating organic waste and turning it into compost or bioenergy improves soil fertility and provides an alternative energy source. Reducing the estimated one-third of all food that is lost or wasted can also improve air quality.
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. Fine particles of dust can travel thousands of miles on the back of these storms, which may also carry pathogens and harmful substances, causing acute and chronic respiratory problems.
