Coal Mining


Coal mining, extraction of coal deposits from the surface of Earth and from underground.
Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy.

Industrial processes


Industrial processes are procedures involving chemical, physical, electrical or mechanical steps to aid in the manufacturing of an item or items, usually carried out on a very large scale. Industrial processes are the key components of heavy industry

Agriculture


Agricultural waste is waste produced as a result of various agricultural operations. It includes manure and other wastes from farms, poultry houses and slaughterhouses; harvest waste; fertilizer run- off from fields; pesticides that enter into water, air or soils; and salt and silt drained from fields.

Effects of Climate Change

  • According to the World Economic Forum’s Global Risks Report 2021, the failure to mitigate and adapt to climate change is “the most impactful” risk facing communities worldwide—ahead of even weapons of mass destruction and water crises.
  • Blame its cascading effects: As climate change transforms global ecosystems, it affects everything from the places we live to the water we drink to the air we breathe.

Extreme weather
  • As the earth’s atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier.
  • Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.

Dirty air
Air pollution and climate change are inextricably linked, with one exacerbating the other. When the earth’s temperatures rise, not only does our air get dirtier—with smog and soot levels rising accordingly—but it also becomes filled with more allergenic pollutants, such as circulating mold (thanks to damp conditions from extreme weather and more floods) and pollen (due to longer, stronger pollen seasons).
Health risks
  • According to the World Health Organization, “climate change is expected to cause approximately 250,000 additional deaths per year” between 2030 and 2050. As global temperatures rise, so do the number of fatalities and illnesses from heat stress, heatstroke, and cardiovascular and kidney disease.
  • And as air pollution worsens, so does respiratory health—particularly for the 300 million people living with asthma worldwide; there’s more airborne pollen and mold to torment hay fever and allergy sufferers too.

Rising seas
  • The Arctic is heating up twice as fast as any other place on the planet. As its ice sheets melt into the seas, our oceans are on track to rise by anywhere from 0.95 to 3.61 feet by the end of this century, threatening coastal ecosystems and low-lying areas.
  • Island nations face particular risk, as do some of the world’s largest cities, including New York City, Miami, Mumbai in India, and Sydney in Australia.
