Environmental issues are harmful or bad effects of human activity on biophysical environment. Environmental issues arise mainly through voluntary actions of humans. We are going to discuss some of the human actions which are causing issues to the environment. These include: Industrialization, Hydrology, Nutrient Pollution, Overgrazing, and Overpopulation.
The Industrial revolution begun in Britain and spread to the rest of countries. It has a great impact on human society. It has changed the overall dynamics of human species. I has also a great impact on the environment, with the increase in Industries it boost up air pollution which include Carbon dioxide, which is the main agent responsible for the depletion of ozone layer (O3). With the depletion of ozone layer it allows Harmful rays to hit surface of earth. These rays cause a lot of skin problems
Hydrology is the scientific study of the distribution, movement, quality of water on the planet. Scientists have found out that due to use of different pesticides and chemical causes damages to the overall quality of water because of which human health is at risk because 70% of our body is composed of water. Blood contain 90% of water. Other hydrological hazards Includes flood, Drought, Coastal erosion etc.
Overpopulation has been a growing concern for the world. It is creating a lot of problems for the human species, and many of the Environmental issues can be linked with overpopulation such as loss of fresh water, lower life expectancy in fast growing countries or should I say third world countries India, Pakistan, Bangladesh . Depletion of natural resources means few resources are chased by many people which will cause competition among humans and extremely will increase crimes.
Overgrazing is herb ivory (animal consumption of plants) which extract the unsustainable yield of floral biomass from an ecosystem. Overgrazing occurs when plants are exposed to grazing for a longer period of time. It causes environmental problems such as soil erosion, land degradation and loss of useful species. Soil gets eroded when the cover of vegetation almost gets removed from the land and exposed to the strong wind, rainfall.
Nutrient pollution is the process where too many nutrients are added to water mainly phosphorus, and nitrogen as a fertilizer. This is then responsible for excessive growth of Algae. The harmful effect of nutrient pollution includes Acid rain, Air pollution, and direct exposure to algae.
Acid rain: Acid rain is caused by nutrient pollution in the air. Acid rain is very dangerous and when it happens it destroys lakes, streams, Forest, Grassland.
Direct exposure to algae: Harmful algae blooms in water produces toxins which kill fish and many more aquatic animals. It is not only their toxins that affect aquatic life. Even if they do not produce toxins they can harm aquatic animals by blocking sunlight from them.
In order to preserve the natural beauty of our environment we must refrain from those activities which causes Environmental issues. It is important to become actively involved in helping to enhance our environment with everyday solutions to our daily activities. Make changes and let your friends, family, and neighbors know what is important and how they can help in making these changes. With everyone working together we can create a healthy and cleaner environment for yourself and others.
