Effect of Human Activities on the Environment

Humans have various influences on the environment. Common implications include declining water quality, increasing pollution and greenhouse gas emissions, depleting natural resources, and contributing to global climate change. Some of them are direct results of human activities, others are part of a series of behaviors and reactions due to secondary influences.

One of the greatest human impacts on the water system is the introduction of excess nutrients. Nutrients such as nitrogen and phosphorus are essential for the health and survival of aquatic plants and animals. However, humans introduce large amounts of nutrients primarily through overuse of fertilizer. Too much nutrients can rapidly reduce water quality by breeding certain bacteria and algae that use oxygen necessary for the survival of other species. A further problem is that these nutrients can be carried to other streams, rivers and bays downstream. Therefore, nutrients can lower the quality of water away from where they were originally introduced.

Most air pollution is the result of human activity. For example, as combustion of fossil fuels from automobiles, industrial plants and power plants increases, large amounts of air pollutants (carbon monoxide, ozone, nitrogen oxides, etc.) are emitted into the atmosphere. Other air pollutants such as lead-based compounds can cause serious health effects such as cancer, or other types of reproductive effects or birth defects

According to the US Environmental Protection Agency, human activities are the main cause of the global temperature rise mainly due to carbon dioxide and other greenhouse gas emissions. Temperature rise brings about changes in areas where agricultural crops grow and areas where certain fish and animals can be seen. It is essential to provide food to the population increase. Global temperature rise also threatens the economy that melts glaciers, releases water that raise the sea level, and relies on coastal communities and coastal resources.

People can do a few simple things everyday to minimize environmental impact. For example, if you use public transport or cycling or walking instead of driving, carbon dioxide emissions will be reduced. Reducing the amount of fertilizer applied to lawn, gardens, and vegetables will reduce the possibility of neighboring water pollution. It also helps drinking water and human health. Using less energy at home can reduce the amount of air pollution from coal-fired power plants. Activities to reduce water and energy consumption will have a positive impact on our environment.

Jonas Martonas has worked diligently about the environment for over 10 years. He has seven years experience in evaluating and preparing technology reports for various government agencies. Martonas is the main author of hundreds of government technical reports and is posted on various websites. He holds a master's degree in the science of environmental science

Environmental problems are the harmful effects of human activity on the biophysical environment. Environmental protection is a way to protect the natural environment at the individual, organization, or government level for the benefit of the environment and humanity. Environmentalism is a social and environmental movement that addresses environmental issues through advocacy, education and behavior. Carbon dioxide equivalent amount of atmospheric greenhouse gas (GHG) exceeds 400 ppm (NOAA) ("long-term total greenhouse gas emissions exceeds 455 ppm) (Intergovernmental Panel on Climate Change Report) . This level is considered a turning point. "The amount of greenhouse gases in the atmosphere is beyond the threshold that could lead to dangerous climate change, and we are already facing many risks in the field of pollution.
