Environment The natural environment encompasses all living and non-living

things occurring naturally on Earth or some region thereof. It is an environment that encompasses the interaction of all

living species. Complete ecological units that function as natural systems

without massive human intervention, including all vegetation, microorganisms, soil, rocks, atmosphere, and natural phenomena that occur within their boundaries.

Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from human activity.

Environmental Issues Environmental issues are harmful aspects of human activity on

the biophysical environment. Environmentalism, a social and environmental movement that

started in the 1960s, addresses environmental issues through advocacy, education and activism

For example the carbon dioxide equivalent of greenhouse gases in the atmosphere has already exceeded 400 parts per million. This level is considered a tipping point.

The greenhouse gases in the atmosphere is already above the threshold that can potentially cause dangerous climate change. We are already at risk...It's not next year or next decade, it's now.

Air pollution

Air pollution introduction of chemicals, particulates, or biological

materials into the atmosphere cause discomfort, disease, or death to humans, damage

other living organisms such as food crops, or damage the natural environment or built environment.

Atmosphere - complex dynamic natural gaseous system which is essential to support life on planet Earth.

Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.

Indoor air pollution and urban air quality are listed as two of the World’s Worst Toxic Pollution Problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.

Water pollution

Water pollution Water pollution is the contamination of water bodies (e.g. lakes,

rivers, oceans, aquifers and groundwater). Water pollution occurs when pollutants are discharged directly

or indirectly into water bodies without adequate treatment to remove harmful compounds.

Water pollution affects plants and organisms living in these bodies of water.

In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

Noise pollution

Noise pollution Noise pollution is displeasing or excessive noise that may

disrupt the activity or balance of human or animal life. The source of most outdoor noise worldwide is mainly caused

by machines and transportation systems, motor vehicles, aircrafts, and trains.

Indoor noise is caused by machines, building activities, music performances, and especially in some workplaces.

High noise levels can contribute to cardiovascular effects in humans, a rise in blood pressure, and an increase in stress and vasoconstriction, and an increased incidence of coronary artery disease.

In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.
