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

 

 

ENVIRONMENTAL MOVEMENT  
The environmental movement, a term that includes conservation and green politics, is a diverse scientific, social, and political movement for addressing environmental issues. Environmentalists advocate the sustainable management of resources and stewardship of the environment through changes in public policy and individual behavior. In its recognition of humanity as a participant in (not enemy of) ecosystems, the movement is centered on ecology, health, and human rights.
The environmental movement is an international movement, represented by a range of organizations, from the large to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. At its broadest, the movement includes private citizens, professionals, religious devotees, politicians, scientists, nonprofit organizations and individual advocates.


Chipko Movement
The forests of India are a critical resource for the subsistence of rural peoples throughout the country, but especially in hill and mountain areas, both because of their direct provision of food, fuel and fodder and because of their role in stabilising soil and water resources. As these forests have been increasingly felled for commerce and industry, Indian villagers have sought to protect their livelihoods through the Gandhian method of satyagraha non-violent resistence. In the 1970s and 1980s this resistance to the destruction of forests spread throughout India and became organised and known as the Chipko Movement.
The first Chipko action took place spontaneously in April 1973 and over the next five years spread to many districts of the Himalaya in Uttar Pradesh. The name of the movement comes from a word meaning 'embrace': the villagers hug the trees, saving them by interposing their bodies between them and the contractors' axes. The Chipko protests in Uttar Pradesh achieved a major victory in 1980 with a 15-year ban on green felling in the Himalayan forests of that state by order of India's then Prime Minister, Indira Gandhi. Since then the movement has spread to Himachal Pradesh in the North, Kamataka in the South, Rajasthan in the West, Bihar in the East and to the Vindhyas in Central India. In addition to the 15-year ban in Uttar Pradesh, the movement has stopped clear felling in the Western Ghats and the Vindhyas and generated pressure for a natural resource policy which is more sensitive to people's needs and ecological requirements

Water Pollution in India

The Polluted Ganga River
It's nice to know that our work is being recognized by a government institute in India and being presented at the highest level," said Steve Hamner, research associate in microbiology. "Lots of things get done judicially in India."
The Ganges River is considered a goddess, but Tim Ford, head of MSU's microbiology department, said it has become a soup of pollution.
"It's a beautiful river. It's just really mucked up," he commented.
The river contains untreated sewage, cremated remains, chemicals and disease-causing microbes, the researchers said. Cows wade in the river. People wash their laundry in it and drink from it. Ford said the Ganges has become the kind of place where genetic material could transfer between pathogens and create new pathogens.
"Wastewater treatment is critical to protecting human health from waterborne diseases," Ford said. "The Ganges River is a major source of disease burden in that region."
Hamner said MSU and a government lab in India each sampled the Ganges and found enterohaemorrhagic E. coli (EHEC) bacteria. The bacteria known as 0157:H7 bacteria. It was first detected in the United States in 1982 after someone ate a tainted hamburger. The Centers for Disease Control and Prevention estimates that 0157:H7 now infects more than 73,000 people and kills about 60 people a year in the United States. The CDC said most of those illnesses have been associated with eating undercooked, contaminated ground beef, drinking unpasteurized milk, swimming in or drinking contaminated water and eating contaminated vegetables. The bacteria can cause dysentery and kidney failure. It occasionally kills

Green Car, Green Environment




A hybrid car is quite similar to a gasoline-powered car except that, in this case, there are two or more sources of power (unlike regular cars which have one common power source - gasoline or diesel). In a hybrid car, one source of power is generally gasoline, whereas the other power sources could be any of the following:
  • Solar energy
  • Pressurized or compressed air
  • Electric batteries
  • Fuel cells
  • Liquid petroleum gas (LPG)
  • Liquified nitrogen
  • Hydrogen
  • Alternative fuels and biofuels
  • Wind energy
  • Manpower

ENVIRONMENTAL 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.
