NATURAL RESOURCES CLASS OF 2014 BSC IT By: Richa Singh Lecturer, AIIT1/1/12
Natural Resources Natural resources occur naturally within environments that exist relativelyundisturbed by mankind , in a natural form. A natural resource is often characterized by amounts of bio-diversity and geo-diversity existent in various ecosystems. Natural resources are derived form the environment. Many of them are essential forour survival while others are used for satisfying our wants. Click to edit Master subtitle style
ManagementNatural resources management is a discipline in themanagement of natural resources such as land , water , soil ,plants and animals , with a particular focus on howmanagement affects the quality of life for both present andfuture generations.Natural resource management is interrelated with theconcept of sustainable development , a principle that formsthe basis for land management and environmentalgovernance throughout the world.In contrast to the policy emphases of urban planning andthe broader concept of environmental management , naturalresource management specifically focuses on a scientific andtechnical understanding of resources and ecology and the lifesupporting capacity of those resources.
DepletionIn recent years , the depletion of natural resources and attemptsto move to sustainable development has been a major focus ofdevelopment agencies.This is a particular concern in rain forest regions , which holdmost of to edit Master subtitle style Click the Earth’s natural bio-diversity – irreplaceable geneticnatural capital of natural resources is the major focus of naturalcapitalism , environmentalism , the ecology movement and greenpolitics. Some view this depletion as a major source of social unrestand conflicts in developing nations.Mining , petroleum extraction , fishing , hunting and forestry aregenerally considered natural resource industries. Agriculture isconsidered a man made resource.
ProtectionConservation biology is the scientific study of the natureand the status of the Earth’s bio-diversity with the aim ofprotecting species , their habitats and ecosystems fromexcessive rates of extinction.It is an interdisciplinary subject drawing on sciences ,economics and the practice of natural resourcemanagement.Habitat conservation is a land management practicethat seeks to conserve , protect and restore , habitat areasfor wild and plants and animals especially conservationreliant species and prevent their extinction ,fragmentation or reduction in range.
HMMMM....What do you think nonrenewable resources are? Break it down... Nonrenewable?
NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!
COAL, PETROLEUM, AND GAS Coal, petroleum, and natural gas are considerednonrenewable because they can not be replenished in a short period of time. Theseare called fossil fuels.
WHAT WAS THE DIFFERENCE BETWEEN COAL AND OIL/GAS?
All are fossil fuels which means that they wereformed from plants and animals from millionsof years ago.Coal is a solid. It is mostly carbon. It is madefrom mostly plant materials.Oil is a liquid. It is a mixture of hydrocarbons.It is more animal materials. Its composition isdifferent depending on where it is found.Natural gas is a gas. It is mostly methane, CH4.
HMMMM.... If nonrenewable resources are resourcesthat cannot be re-made at a scale comparable to its consumption, what are renewable resources?
RENEWABLE RESOURCESRenewable resources arenatural resources that can bereplenished in a short periodof time.● Solar ● Geothermal● Wind ● Biomass● Water
SOLAR Energy from the sun. Why is energy from the sun renewable?
This form of energy relies on the nuclear fusion powerfrom the core of the Sun. This energy can be collectedand converted in a few d ifferent ways. The range isfrom solar water heating with solar collectors or atticcooling with solar attic fans for d om estic use to thecom plex technologies of d irect conversion of sunlightto electrical energy using m irrors and boilers orphotovoltaic cells. U nfortunately these are currentlyinsufficient to fully power our m od ern society.
GEOTHERMAL Energy from Earth’s heat.Why is energy from the heat of the Earth renewable?
