What is environment? What is environmental pollution?
The environment is defined as the totality of man’s surroundings, comprising both natural and man-made resources. Natural resources include land, water, air, fauna, flora, and raw materials, whereas man-made resources include cultural heritage, socio-economic institutions, and people.
Environmental pollution refers to the injection of harmful substances into the environment, which is largely the result of industrial production. It changes the physical, chemical, and biological characteristics of air, land, and water. Pollution harms human life and other species, degrades living conditions, and renders the environment unfit to preserve normal life.
