Do you always measure up to your responsibilities to the environment? Do you fall short? Explain why or why not.© BrainMass Inc. brainmass.com October 9, 2019, 8:50 pm ad1c9bdddf
Global warming, Ozone depletion and acid rain are some of the burning environmental issue for the mankind. Global warming occurs due to excessive accumulation of Greenhouse gases (GHGs). These are gaseous components of the atmosphere that contribute to the greenhouse effect. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases. Major cause of the increased greenhouse gas is anthropogenic activities. Some of the main sources of greenhouse gases due to human activity include:
a. burning of fossil fuels and deforestation leading to higher carbon dioxide concentrations
b. paddy rice farming, land use and wetland changes, pipeline losses, and covered vented landfill emissions contributes methane to atmospheric concentrations
c. use of chlorofluorocarbons (CFCs) in refrigeration systems, and use of CFCs and halons in fire suppression systems and manufacturing processes
d. agricultural activities, including the use of fertilizers, that lead to higher nitrous oxide concentrations
