How Do Humans Affect the Environment?
Unfortunately, humans are the most polluting species. Earth is very good at recycling waste, but people are generating far more than earth can cope with. Pollution occurs at different levels and it doesn’t just impact our planet; it impacts all species, including mankind, who dwell on it.
Pesticides, herbicides, large landfills, waste from food processing industries, and nuclear waste generated from nuclear reactors and weapons deplete our soil of its nutrients and make it virtually lifeless. According to the Environmental Protection Agency, “Usually, contaminants in the soil are physically or chemically attached to soil particles, or, if they are not attached, are trapped in the small spaces between soil particles.”
Effluence from industries, fertilizer run off, and oils spills all damage fragile ecosystems. According to the Water Project, “Nearly a billion people do not have access to clean and safe water in our world.” Worldwatch Institute says, “The 450 million kilograms of pesticides U.S. farmers use every year have now contaminated almost all of the nation’s streams and rivers, and the fish living in them, with chemicals that cause cancer and birth defects.”
Burning of fossil fuels and toxic gases produced in factories causes pollution. Air pollution infects the environment and threatens the health of all who inhabit the earth. According to the United Nations, “The estimations we have now tell us there are 3.5 million premature deaths every year caused by household air pollution, and 3.3 million deaths every year caused by outdoor air pollution.”
Global Warming and Ozone Layer Depletion
Carbon footprint is the measure of direct or indirect CO2. Greenhouse gases like CO2 and methane are believed to lead to global warming. Chlorofluorocarbons (CFCs), used in refrigeration, and aerosols destroy the ozone layer that shields the earth from UV rays. https://greenliving.lovetoknow.com/How_Do_Humans_Affect_the_Environment
