ENVIRONMENTAL EDUCATION Computer Engg.

SYLLABUS Ø Defination, Scope, and importance of Environmental Education. Ø Basic of ecology, biodiversity, eco system and sustainable development. Ø Source of pollution- natural and manmade, cause, effects and control measure of pollution (air, water, noise, soil, radioactive and nuclear) and their units of measurement. Ø Solid waste management –Cause, effect and control measures of urbun and industrial waste.

SYLLABUS � Mining and deforestation- Cause, effect and control measures. � Environmental legislation-Water (preventation and control of pollution) Act 1974, Air(preventation and control of pollution) Act 1981 and Environmental Protection Act 1986, Role and functio of state pollution Control Board, Environmental impact Assesment(EIA). � Role of Non-convential Energy Resources. � Current Issues in Environmental Pollution-Global Warming, Green House Effect, Depletion of Ozone Layer, Recycling of Material, Enivironmental Ethics, Rain Water Harvesting, Maintainance of Groundwater, Acid Rain, Carbon Credits.

Environmental Education is the process of recognizing values and clarifyingts concept in order to develop skills and attitudes necessary to understand appericate the inter relatedness among men, his culture and his biophysical surrounding.

Scope of Environmental Education � Environmental pollution and its control. � Conservation of natural resources. � Population explosion and its control. � Green technologies. � Ecological study. � Research & development (R & D) in environment. � Environment consultancy.

Importance of Environmental Education � It help us in careful handling the issues like pollution menace, over explotion of natural resources, food security etc. � Environmental education helps in inculcating attitudes and values conducive to environmental protection. � Environmental Education train us to conserve our fast depleting natural resources. � Environmental has been a source of happiness for men and time has come to preserve this happiness for man by imparting environmental education. � It helps to understand different food chain ecological balance in nature.

Ecology � Ecology deals with the study of interaction of living organisms with their surroundings. � Biotic: Biotic related living factors. E. g. Plants, animals, fungi etc. � Abiotic: Abiotic are non- livig factor that affect living organism. E. g. pond, lake, rain, snow etc.

Biodiversity � Biodiversity can be defined as, ”the variety and variability among living organisms and the ecological complexes in which they occur. ”

Ecosystem � An ecosystem is defined as a natural ecological unit comprising of living organisms and non living environmental that interact to form a stable self supporting system. A pond, desert are example of ecosystems.

Sustainable development � Sustainable development is defined as as”meeting the need of the present without compromising the ability of future generations to meet their needs.

Environmental pollution � Any undesirable change in chemical, physical , biological characterstics of any component that effect the life is called environmental pollution.

Source of Pollution � Pollution is the process through which harmful substances are added to the environmental by human or natural activites. � Source of pollution. � i) Natural pollution � Ii) Man-made or Anthropogenic pollution

Type of Pollution � Air Pollution � Water Pollution � Soil Pollution � Noise Pollution � Radioactive or Nuclear Pollution

Solid Waste � Solid Waste in the broader sense include all the discarded solid materials from residence, industries, buisness houses, agriculture etc. Cause of increase in Solid Waste � Over-population � Urbanisation � Affluence � New technology

Effect of Solid wastes � Spoilage � Pollution � Effect of landscape on soil � Effect on terristial and aquatic life � Health Hazards

Method of Solid Waste Disposal � Composting � Incineration � Landfilling � Vermiculture � Recycling

Mining � The process of taking out minerals on their ores from the earth. Effect of Mining �i)Ecological effects �ii)Physical effects �iii)Environmental effects �iv)Occupational health effects �v)Socio-economic effects

Deforestation � Deforestation is defined as the reckless felling oftrees by human beings for their selfish needs. Cause of Deforestation �Infrastructure Projects �Urban construction �Growing food needs �Grazing land �Feel requirements �Forrest fire �Illegal loggin

Effects of deforestation � Decrease in rainfall � Loss of fertile land � Soil erosion � Expansion of deserts � Lowering of water table � Effect onclimate � Loss in biodiversity � Economic loss � Environmental changes

Environmental Legislations � Legislation provides a framework for regulating use of the environment. It is curial for environmental management in a number of ways. Environmental law concern regulation of activities affecting the environment. Environmental law encourage satisfactory performance, enable authorities to punish those who infringe environmental legistation.

Environmental ACT � WATER(Prevention and Control of Pollution)ACT-1974 � AIR(Prevention and Control of Pollution)ACT 1981 � ENVIRONMENTAL PROTECTION ACT-1986

Environmental Impact Assesment � An Environmental Impact Assesment(EIA) is an assessment of the possible positive or negative impacts that a proposed project may have on the environment, together consisting of the environmental, social and economic aspects.

Role of Non-Conventional Resources of Energy � i) Self –renewable resources � ii) Clean sources of energy � iii) Helpful in protecting the environment � iv) Cheap resources of energy � v) Helpful in rural development

Different Non-Conventional Resources of Energy � 1)Solar Energy � 2)Wind Energy � 3)Ocean thermal Energy � 4)Giothermal Energy � 5)Biomass Energy

Greenhouse Effect � The greenhouse effect is a naturally occuring phenomena that is responsible for heating of Earth’s surface and atmosphere.

Global Warming � Increase in concentration of greenhouse gases is enhanching the greenhouse effect, threby increansing the average surface temprature beyond 15 celcius, on the global scale, this effect is known as global warming.

Depletion of Ozone Layer � Earth has a natural sunscreen in the stratosphere like a blanket which is called Ozone Layer. Due to increase in green house gases, deplation of ozone layer is widely occuring.

Carbon Credit � Carbon Credit can also be defined as”a certificate showing that a government or company has paid to have a certain amount of carbon dioxide removed from the environment. ”

Environmental Ethics � Environmental ethics refers to the issues, principles and guidelines relating to human interactions with their environment. ”Ethics” means the character of a person as described by his or her actions.

Rainwater Harvesting � Rainwater harvesting is a technique of collecting rainwater and storing it by constructing special water-harvesting structure for later use. It not only increase water availability but also checks the declining water table.
