The silent killer
We can no longer dispute that global warming is a reality.
Greenhouse gases trap the earth’s heat in the atmosphere which leads to warmer temperatures, rising sea levels, increased extreme weather conditions, heat-related deaths and the increased transmission of infectious diseases.
Greenhouse gases include carbon dioxide, which comes from burning fossil fuels such as petrol and natural gas. Methane gas and hydrofluorocarbons (HFCs) are also deadly air pollutants that play a destructive role in climate change. Factories release sulphur dioxide into the air we breathe.
Intense factory farming also produces enormous amounts of greenhouse gas in the form of methane, released by animal dung.
Smog is generated by cars and trucks, factories, power plants, incinerators, engines and anything that burns fossil fuels such as coal, petrol or natural gas and can irritate the eyes and throat and also damage the lungs.
Other hazardous air pollutants can include mercury, lead, dioxins and benzene. Mercury affects the central nervous system. Lead in large amounts can damage children’s brains and kidneys and affect their IQ and ability to learn. Benzene is classified as a carcinogen.
Polycyclic aromatic hydrocarbons, or PAHs, are toxic components of traffic exhaust emissions and wildfire smoke. In large amounts, they have been linked to eye and lung irritation, blood and liver issues, and even cancer. In one recent study, the children of mothers who’d had higher PAH exposure during pregnancy had slower brain processing speeds and worse symptoms of ADHD. (Ref www.nrdc.org)
