Role of individual in preserving natural resources for their

equitable maintenance

Page 2: Environmental science priyanka

Natural resourcesResources that occur naturally and meet the

desires of the entire living beings are known as natural resources. They resources are considered valuable in their relatively unmodified (natural) form.

A commodity is generally considered a natural resource when the primary activities associated with it are extraction and purification, as opposed to creation.

All the natural resources come from environment. some of them are essential for our survival while most of them are essential for satisfying our wants.

A country's economic standing and independence are base on long-term sales of its natural resources, also known as commodities, to other nations.

Today, population explosion and incresase in man’s greedy nature have become the main causes for exploitation of natural resources.

Page 3: Environmental science priyanka

Natural resouces are classified into two Types basing on their origin.

They are:• BIOTIC:These are also known as the

living resources.These are the renewableresources and include the plants and animals. Examples of biotic resources are forests, plants, animals, birds, fish, and marine organisms. Mineral fuels can be, but not always are, regarded as biotic resources since they are derived from or products formed from decayed organic matter.

ABIOTIC:Abiotic resources are resources that are nonliving. These resources fall into the larger category of natural resources, which occur naturally in the environment and are not created or produced by humans or humanactivity.examples are minerals,water,land,energy resources etc…

Classification of natural resources

Page 4: Environmental science priyanka

Basing on their availability natural resources are classified into two types.They are:1. Renewable resources2. Non-renewable resources

Page 5: Environmental science priyanka

A renewable resource is a naturalresource with the ability toreproduce through biological ornatural processes and replenishedwith the passage of time. Renewableresources are part of our naturalenvironment and form our ecosystem

•Renewable resources are those whose supply becomes available foruse at different time intervals and in which present use does not diminishfuture supply.

•Tree and plant biomass, water and wildlife are a few renewable‘natural’ resources.

•Renewable sources have low carbon emissions, therefore they are considered as green and environment friendly.

Renewable resources:

Page 6: Environmental science priyanka

Non-renewable resources:

A non-renewable resource is a natural resource which cannot be reproduced, grown, generated, or used on a scale which can sustain its consumption rate, once depleted there is no more available for future needs.

•Non-renewable sources are not environmentalfriendly and can have serious affect on our health.

•Non-renewable sources will expire some day and we have to us our endangered resourcesto create more non-renewable sources ofenergy.

•Non-renewable sources release toxic gases inthe air when burnt which are the major cause for global warming.

•Examples for non renewable resources are fossil fuels, natural gas, oiland coal.

Page 7: Environmental science priyanka

Types of natural resources

Different types of natural resources are:

Forest resourcesWater resourcesMineral resourcesFood resourcesLand resourcesEnergy resources

Page 8: Environmental science priyanka

Forest resourcesForests are classified into :

• Tropical forests• Temperate forests• Coniferous forests

Threats to forest resources:Deforestation: process of

cutting doun the trees inarid, semi arid, moist regions isknow as deforestation.causesfor deforestation are timber extraction,damconstruction,cultivation,mining,pollution..etc

Page 9: Environmental science priyanka

Measures to control deforestation

• Implement afforestation programmes• Overgrazing of cattle should be

reduced•Control the usage of paper•Forest conservation act

should be strictly implemented

• Recycle and buy recycled products.

• When a tree is cut,one plant should be grown in order to maintain balance.• Educate people on ecological value of tree, reduce use of timber, plant• Provide alternate fuel to the forest fringe poor people to reduce pressure on firewood for daily need.

Page 10: Environmental science priyanka

Water resourcesThreats to water resources:

• Dumping industrial waste• Dumping pesticides and

organic waste• Eutrophication• Bio magnification• Thermal pollution• Oil spills

Page 11: Environmental science priyanka

Measures to conserve water resources Rain water harvesting must be done.

Sewage treatment should be implemented.

Use drip irrigation for shrubs andtrees to apply water directly to theroots where it's needed.

Use a water-efficient showerhead. They're inexpensive, easy to install, and can save you up to 750

gallons per month.Look for products bearing

the EPA WaterSense Label for items that been certified to save 20% or more withoutsacrificing performance.

Water-saving steam sterilizers, for use in hospitals and health care facilities.

Improved water management practices that reduce or enhance the beneficial use of water.

Page 12: Environmental science priyanka

Mineral resources• A 'Mineral Resource' is a concentration or occurrence of material of

intrinsic economic interest in or on the earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction

Mineral resources are classifies into metallic and non metallic:• Metallic:examples are iron,alluminium, copper,gold.etc..• non-metallic: examples are coal,gypsum, silica ,limestone.etc..

Threats of mining:•Disturbance to mantle layer•Earthquakes•Tsunami•Drowning of land•Deforestation•Acid mine drainage

Page 13: Environmental science priyanka

Conservation methods Implementation of bio-mining/leaching technology. Enhanced oil recovery (eor). Usage of bio fuels. Surface mining control and reclamation

act should be strictly implemented. Mining activities should me done under strict supervision of authorities The mined out areas have to be back

filled and then rehablitated for development of vegetation.

Food resourcesFood is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.

Page 15: Environmental science priyanka

Conservation of food resourcesImplement the following methods to get chemical free food.:

Organic farming:it is a process in which both modern and traditional methods of farming are utilized.

Mulching:process of adding or layering dry leaves Composting:conversion of complex materials into simpler ones with the

help of micro organisms. Usage of Green manure.

Page 16: Environmental science priyanka

Crop rotation method

Terrace/contour farming

Page 17: Environmental science priyanka

Land resourcesland occupies nearly 20 percent of the earth surface. It covers around 13000 million hectares of the area. The houses, roads and factories occupy nearly one third of the land. The forests occupy another one third of the land. The rest of land is used for ploughing and for meadows and pastures. The soil forms the surface layer of land which covers more than the 80 percent of land.

Page 18: Environmental science priyanka

Conservation of land resources

Measures to overcome soil erosion1. Biological control:adapting of some living systems to improve

fertility.they areA. MulchingB. PolycultureC. Crop rotation

2. Mechanical control:A. Contour ploughing is a measure to conserve our land.

By this method, the fields are ploughed, harrowed and sown along the natural contour of the hills.

B. By terracing method: A series of wide steps are made along the slop following the contours. This method is very common in rice growing regions.

3. By educating, informing and sensitizing all landholders about various aspects of this precious resources and their sustainable use

4. Under the afforestation and reforestation programmes, planting of trees, bushes and grass help to check the soil erosion.

Page 19: Environmental science priyanka

5. Strict actions are taken to check reckless felling of trees and overgrazing.6. Shelter belts (rows of trees) are planted on the margins of desert areas to check the fury of wind.7. Construction of dams and gully-trap inculcate the water-harvesting.

Shelter belts

Energy resources Energy is the capacity to do work and is required for life processes. An

energy resource is something that can produce heat, power life, move objects, or produce electricity.

Matter that stores energy is called a fuel.   Energy resources are Classified into two types.They are:

• Renewable:solar energy, wind energy,tidal energy, geothermal energy etc..

• Non renewable energy: coal,petrol,diesel.etc..

Page 21: Environmental science priyanka

Conservation of energy resources

• CFLs use 60% less energy than a regular bulb. This simple switch will save about 300 pounds of carbon dioxide a year.• Change your travel behaviour, think more in terms of public transportation, if possible, walk or ride your bicycle instead of taking the car.• Turn off lights and appliances when you are not using them, use energy-saving light bulbs.• Use a microwave instead of a stove to reheat food.• Use rechargeable batteries instead of disposable batteries.• Install skylights in the roof or walls to reduce the need for artificial lighting. • Plant shade trees and paint your house a light color if you live in a warm climate, or a dark color if you live in a cold climate. Reductions in energy use resulting from shade trees and appropriate painting can save up to 2.4 tons of CO2 emissions per year. (Each tree also directly absorbs about 25 pounds of CO2 from the air annually.)• Don’t overload refrigerators; they operate more efficiently when air circulation is not restricted.
