Prepare an article for newspaper on the item,"how human activities effects the environment?
Answers
The population and activities of every species are governed by the resources available to them & interaction among species is quite common. The waste product of one species may form the food supply of another species
Humans alone have the potential to gather resources from beyond their immediate surroundings and process them into different and more versatile forms. This has made humans to thrive and flourish beyond natural constraints. As a result of which the anthropogenic (man-induced) pollutants have overloaded the system, and the natural equilibrium is disturbed.
Rapid development activities have been associated with more and more exploitation of various natural resources. Technological development has resulted in fast depletion of non-renewable energy resources, mainly coal and petroleum, and also various minerals. Mining activities, dam, building, urbanization and industrialization have all interfered with the ecological balance of nature due to large scale impact.
Primitive humans used natural resources to satisfy their basic needs of air, water, food and shelter. These natural and unprocessed resources were readily available in the biosphere, and the residues produced by the use of these resources were generally compatible with or easily assimilated by the environment.
With the dawn of the industrial revolution, humans were better able than ever to satisfy their needs for air, water, food and shelter. So, humans turned their attention to other needs beyond those associated with survival.
Automobiles, household appliances, processed foods and beverages, etc. have now become as popular as to seem necessities, and meeting these acquired needs had become a major thrust of modern industrial society. These acquired needs are usually met by items that must be processed or manufactured or refined.
The production, distribution and use of such items usually results in more complex residuals and/or wastes, many of which are not compatible with or readily assimilated by the environment. As the acquired needs (or luxuries) increase so will the complexity of the production chain, and mass and complexity of the pollutants generated.
