  • 1. ENVIRONMENT
  • 2. ENVIRONMENT
  • 3. WHAT IS ENVIRONMENT • Environment (biophysical), the physical and biological factors along with their chemical interactions that affect an organism • Environment (systems), the surroundings of a physical system that may interact with the system by exchanging mass, energy, or other properties • Environments (series), a series of LPs, cassettes and CDs depicting natural sounds • Built environment, constructed surroundings that provide the setting for human activity, ranging from the large-scale civic surroundings to the personal places • Knowledge environment, social practices, technological and physical arrangements intended to facilitate collaborative knowledge building, decision making, inference or discovery • Natural environment, all living and non-living things • Social environment, the culture that an individual lives in, and the people and institutions with whom they interact • Physical environment, in ecology
  • 4. ENVIRONMENTAL ISSUES • Environmental issues are harmful aspects of human activity on the biophysical environment. Environmentalism, a social andenvironmental movement that started in the 1960s, addresses environmental issues through advocacy, education and activism. current problems faced by the environment- • The carbon dioxide equivalent of greenhouse gases (GHG) in the atmosphere has already exceeded 400 parts per million (NOAA) (with total "long-term" GHG exceeding 455 parts per million). (Intergovernmental Panel on Climate Change Report) This level is considered a tipping point. "The amount of greenhouse gas 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." Report from the UN Office for the Coordination of Humanitarian Affairs (OCHA):

  • 6. WORLD ENVIRONMENT DAY • World Environment Day ('WED') is celebrated every year on 5 June to raise global awareness of the need to take positive environmental action. It is run by the United Nations Environment Programme (UNEP). • It was the day that United Nations Conference on the Human Environment began. The United Nations Conference on the Human Environment was from 5–16 June 1972. It was established by the United Nations General Assembly in 1972.[1] The first World Environment Day was in 1973. World Environment Day is hosted every year by a different city with a different theme and is commemorated with an international exposition in the week of 5 June. World Environment Day is in spring in the Northern Hemisphereand fall in the Southern Hemisphere. • "Stockholm was without a doubt the landmark event in the growth of international environmentalism", writes John McCormick in the book Reclaiming Paradise. "It was the first occasion on which the political, social and economic problems of the global environment were discussed at an intergovernmental forum with a view to actually taking corrective action." • World Environment Day is similar to Earth Day.

  • 8. ENVIRONMENT POLLUTION • Pollution is the introduction of contaminants into the natural environment that cause adverse change.[1] Pollution can take the form ofchemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. •

  • 11. EFFECT OF ENVIRONMENT POLLUTION • There are various sources of environmental pollution, such as vehicles, industries, pesticides, deforestation, etc. These include air pollution by vehicles and industries, water pollution by industrial waste and residential sewage, soil pollution by dumping of garbage, radiation pollution by leakage from nuclear plants, noise pollution by vehicles in heavily populated areas, or by supersonic air jets and heavy engineering units.However, the most significant pollution, which is the seed of all other types of pollution, is mental pollution. Every verbal directive an physical action is essentially preceded by thoughts originating in the mind. A polluted mind conceives polluted thoughts, which were then translated into polluted and contaminated words and actions. Negative influences of tin; vices and in particular, sex lust, have led to an unprecedented rise in a global population. This is happening despite the availability of contraceptive methods. To sustain such a progressively multiplying population, more and more commodities are required. Besides essential commodities, the demand for non essential commodities are on the increase, that too merely to satisfy requirements of luxury of the populace. These cull for more and more industries which in turn increasingly contribute In the pollution of the atmosphere, to the ultimate detriment of humanity at huge Due to thought of hatred, jealousy, greed, ego anger, and intolerance, etc , the life especially in megacities is plagued by exploitation, uncertainly, insecurity, worry, anxiety, phobia and stressful mind leading

  • 13. ENVIRONMENTAL DEGREDATION • Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems and the extinction of wildlife. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.[1] • Environmental degradation is one of the Ten Threats officially cautioned by the High Level Threat Panel of the United Nations. • The United Nations International Strategy for Disaster Reduction defines environmental degradation as “The reduction of the capacity of the environment to meet social and ecological objectives, and needs”.[2] • Environmental degradation is of many types. When natural habitats are destroyed or natural resources are depleted, environment is degraded.

  • 16. ECOSYSTEM • An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms, and between organisms and their environment,[4] they can come in any size but usually encompass specific, limited spaces[5] (although some scientists say that the entire planet is an ecosystem).[6] • Energy, water, nitrogen and soil minerals are other essential abiotic components of an ecosystem. The energy that flows through ecosystems is obtained primarily from the sun. It generally enters the system through photosynthesis, a process that also captures carbon from the atmosphere. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.[7]

  • 18. ENVIRONMENTAL PROTECTION • Environmental protection is a practice of protecting the natural environment on individual, organizational or governmental levels, for the benefit of the natural environment and humans. Due to the pressures of population and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960's, activity of environmental movements has created awareness of the various environmental issues. There is no agreement on the extent of the environmental impact of human activity, and protection measures are occasionally criticized. • Academic institutions now offer courses, such as environmental studies, environmental management and environmental engineering, that teach the history and methods of environment protection. Protection of the environment is needed due to various human activities. Waste production, air pollution, and loss of biodiversity (resulting from the introduction of invasive species and species extinction) are some of the issues related to environmental protection. • Environmental protection is influenced by three interwoven factors: environmental legislation, ethics and education. Each of these factors plays its part in influencing national-level environmental decisions and personal-level environmental values and behaviors. For environmental protection to become a reality, it is important for societies to develop each of these areas that, together, will inform and drive environmental decisions.
