The relationship of human beings with nature has been a long one. Human beings have been residents of the environment, and they have also molded the environment. The environment provides human beings with what they need for surviving. It’s this environment that fosters their moral, social, intellectual, and spiritual development. The evolution of human beings on this planet has been a long and winding one. During the evolution, science and technology made inroads and started progressing fast. Science and technology continue to transform the environment in a myriad of ways on a vast scale. World Environment Day is a day that commemorates the preservation of the environment.
The United Nations set this day for marking the importance of protection and development of the environment. The environment deserves this respect for its influence on the happiness of peoples and the economic progress across the world. The date that the United Nations set is the 5th of June. From its inception in the year 1974, the day has developed into a universal platform for the outreach of the people. Over 100 countries celebrate this day. On this day people from the world over are invited to look after the Earth. They are invited to take measures for being a part of the revolution. The Earth stands for biodiversity, natural assets, water, air, and food, and more.
This day has a theme every year. The selected theme concentrates on a pressing environmental issue of that year. The theme for 2019 is “Beat Air Pollution,” and it is for inspiring people to take the problem of this global crisis head-on. China, which is hosting this day this year, has selected this topic. It invites everyone to consider the small and subtle changes in their day-to-day lives for
- Lessening the air pollution that they produce
- Stopping it from contributing to universal warming and affecting their health
Understanding the different sorts of pollution, and their effect on the health of the people and the environment is helpful. It is going to help people to take measures for the improvement of the air that surrounds people. Though you are unable to see it often, air pollution is present everywhere. People must breathe to stay alive. Though they can’t stop breathing, they can take measures regarding the quality of the air around us. As many as nine among ten individuals from the world over are left open to air pollutants that are well past the safe levels that the World Health Organization had set. It is clear that people are up against an urgent task.
People can do their part in reducing air pollution to an extent. An understanding of the sorts of pollution and its effect on the health of people and the environment is important. It will help people take measures for improving the surrounding air.
So, what are the primary sources of the enormous problem of air pollution? They are industries, households, transportation, agriculture, and waste.
Household – The prime reasons for domestic air pollution is the burning of wood, fossil fuels, and more biomass-based fuels indoors. They are used for cooking, heating, and lighting homes. Some 3.8 million early deaths occur from indoor air pollution yearly, and a good number of them happen in the developing countries.
Industry – the production of energy is a prime reason for air pollution in many countries. Power plants that operate on Coal constitute a significant contributor. However, diesel generators are becoming more of a worry in off-grid regions.
Transportation – The universal transport sector is large. It is responsible for nearly 1/4th of energy-associated CO2 emissions, and this number is increasing. Emissions from various means of transportation have accounted for nearly 400,000 early deaths.
Agriculture – the Agriculture sector has two prime sources of air pollution. One is agriculture: livestock, and it manufactures ammonia and methane. The other is the burning of waste that is the result of several agricultural operations. The sources of an estimated 24% of the total greenhouse emissions worldwide are agriculture, woodlands, and more land-use.
Waste – Waste burning out in the open and biological surplus in landfills release detrimental dioxins, methane, furans, and black carbon. Approximately 40 % of worldwide waste is burned in the open.
More sources – Air pollution also come from natural calamities like dust storms, volcanic eruptions, and more natural processes. Dust and sand storms are worrying.
