BIOLOGY DUTY ABOUT NATURAL RESOURCES AND POLLUTION

NATURAL RESOURCES

 Natural resources (economically referred to as land or raw materials) occur naturally within environments that exist relatively undisturbed by mankind, in a natural form. A natural resource is often characterized by amounts of biodiversity existent in various ecosystems.

ž Natural resources are derived from the environment. Many of them are essential for our survival while others are used for satisfying our wants. Natural resources may be further classified in different ways.

žNatural resources are raw materials from the environtment which are used by organism including humans of their continuity of life

RENEWABLE RESOURCES

Renewable resources are ones that can be replenished or reproduced easily. Some of them, like sunlight, air, wind, etc., are continuously available and their quantity is not affected by human consumption. Many renewable resources can be depleted by human use, but may also be replenished, thus maintaining a flow. Some of these, like agricultural crops, take a short time for renewal; others, like water, take a comparatively longer time, while still others, like forests, take even longer.

 Renewable resources are resources that can be produced by natural processes

THE EXAMPLE OF RENEWABLE RESOURCES 

*Wood to build houses is from forest

* Water in your kitchen might come from a wellspring in remote place

NON RENEWABLE RESOURCES

—  Non renewable resources are formed over very long geological periods. Minerals and fossil fuels are included in this category. Since their rate of formation is extremely slow, they cannot be replenished once they get depleted. Of these, the metallic minerals can be re-used by recycling them. But coal and petroleum cannot be recycled.

— Nonrenewable resources are resources that cannot be produced by natural processes.

THE EXAMPLE OF NON RENEWABLE RESOURCES

The example of non renewable:metals such as aluminium, iron, silver uranium, gold, petrolium ,and other of mineral.

Renewable resources such as the movement of  (, including ;  used for ),  (used for ),  (used for ); and  (used for ) are practically infinite and cannot be depleted, unlike their non-renewable counterparts, which are likely to run out if not used wisely. Still, these technologies are not fully utilized. 

POLLUTION

—  A. AIR POLLUTION

—  B. WATER POLLUTION

—  C. SOIL POLLUTION

—  D. ENVIRONTMENTAL POLLUTION

POLLUTION

Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the  i.e. physical systems or living organisms. Pollution can take the form of  or , such as noise, heat, or light. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as  or . The  issues annually a list of the world's worst polluted places.

—  Pollution is its input energy substance, living being, or other component into environmentally so environment situation becomes changed

POLLUTAN

—  Substance or happening causative material it pollution.

—  A Substance was called by pollutan if its existence operated an by environment can evoke loss to other living being.

—  A  Substance  gets to be called by polutan if:

ü a. Amount the overshot normal bounds

ü b. Lie on imprecise place

ü c. Lie at the time which wide of the mark

AIR POLLUTION

 Air so necessary for living thing life is earthed, if air formation experiences changing of normal formation, that air matter was begrimed and air begrimed one gets to trouble man life.

—  Its input scene polutan airs into air so gets to down air  quality 

AIR POLLUTION

  Pollutan :

—   Gases released by industry, motor vehicles, housing, all gases from burning fossil fuels, and CFCs

—   Impact:

—  ~ Earth's temperature rise caused by the greenhouse effect

~ Climate change because rising global temperatures

~ Polar ice melting because of climate change and resulting  sea level rise 

~ Increase of sulfur can cause acid rain

—  How to Handles:

—  ~ Participate in the greening

~ Take care not to disturb or city parks and tree protector

~ Does not do logging, trees and wild plants arbitrarily

~ Reduce fuel use and replace them with electricity or water power

AIR POLLUTAN

Cause of air pollution available  two kinds which is:

1. internal factor, as dust that flies since blown by wind, dust that is issued from flaming mountain eruption, gas gases vulkanik, and waste the process of obsolence.

—  2. external factor (usufruct human activity). e.g. fossil fuel burn result, chemical substance substance using up that is utilized in mid air

 Polutan's component airs:

—  A. Polutan that indigenous smoke which issued by vehicle: carbon monoxide or CO

—  B. Polutan that indigenous gases buangan burn result: oxide nitrogen or NO.

—  C. Polutan that indigenous yielding coal and oil burn: oxide brimstone or SOx

—  D. Particle: particle is polutan's materials airs that gets to form solid

—  E. CFC and Lead

EFFECT OR IMPACT FROM AIR POLLUTION

v Effect air pollution to environmentally and over the world :

·        Acid Rain

·        Ozone Layer Damage

·        Greenhouse Effect and Global Instillation

v  Pollution influence airs to human body:

·        To Eyes

·        To Respiratory Organ

·        To Heart

 

Pollution Influence Airs to Human Body:

—  A. To Eyes : Compound in smoke causes to wink gets water  and pain. If that compound available in number a lot of, sight becomes to elope.

—  B. To Respiratory Organ : ozone causes iritation on nose and throat feels is a-fire. ozone can also minimize lung.

—  C. To Heart : Carbondioxide who is breathed in will get cords with blood cell is constrained in channels oxygen to go to all body. pain on chest because of its low titrates oxygen.

ACID RAIN

—  Coal and oil burn will issue rest substance (issue) in large quantities as sulfurdioksida's substance (SO2), ground particle, and nitrogen dioxide (NO2). If sulfurdioksida and leach oxide in rainwater will evoke acid rain 

EFFECT FROM ACID RAIN

v Acid Rain Effects To Living Things (Animals & Plants):

—  Acid rain can kill plants and animals that can not stand acid.

v Acid Rain Effects for Humans:

~ Hazardous substances that are dissolved in soil fertility and consequently less soil and the tree will die

~ Destroy plant tissues and interfere with plant growth

~ Acid rain causing the water pH falls below normal so disturbed aquatic ecosystems

~ Can damage buildings

v Acid Rain Effects for Building :

—  Acid rain can also damage buildings containing lime or iron.

OZONE LAYER DAMAGE

—  Ozone is shaped oxygen which unstable. Ozone causes pollution if there is at elbow earth surface. functioning ozone layer as protecting as screen sun-shine ultraviolet radiation.

—  Chemical material that can wreck ozone layer : 

—  1. Sprayers chemical substance hall that utilized by luxuriant ala. E.g., hairspray, perfume

—  2. Hall coolant which is CFC = Freon

—  3. Foam is plastic

—  Effort who can be done to tackling ozone layer damage:

—  1. CFC'S purpose limit (freon) In day-to-day life (specifically for AC)

—  2. cut back or substance purpose stop aerosol in spatial spraying

—  3. Purpose stop foams plastic that contains CFC.

Greenhouse Effect and Global Warming

—  Greenhouse makes temperature in it warmer than outside. it because greenhouse absorb solar radiation and prevents it issue. in same trick, atmosphere makes to earth warming regular. So called Greenhouse Effect

—  What ever  gas at atmospheric personation one "greenhouse" ?, Most effective gas bate heat bounce of earth is carbondioxide. carbondioxide particularly being resulted from fossil fuel burn, e.g. smoulder and petroleum stone. if carbondioxide's gas too much, heat that rebounds from earth surface stymied by carbondioxide and rebounding comes down to earth. accordingly, surface temperature earths to increase, This called global warming.

WATER POLLUTION

—  Water pollution is polutan's input water into environmentally water so gets to down water  quality.

—  Begrimed water is water  already deviate from its normal state, and its auspices is:

—  A. Changing pH

—  B. Changing Water Temperature

—  C. Discoloration, Odor, Taste

WATER POLLUTION

¨ Pollutan :

¨ ~ Use as a washing detergent

~ Use of fuels such as petroleum

~ Littering eg. organic waste

~ Excessive use of insecticides

¨ Impact:

¨ ~ Extinction of the organism in water

~ Fish or other aquatic animals can be contaminated with toxic people who eat it

¨ How to Handles:

    ~ Do not throw garbage into the gutter

~ Do not throw liquid waste into sewers or rivers

~ Do not throw away the rest of the drug or insecticide into the ditch or river

WATER POLLUTAN

—  Usufruct human activity that contaminate water which is:

—  A. Industrial waste that contain chemical substance substance that dangerously toxic.

—  B. Family waste, one that consisting of pigswill, slops, bath water  and Urinoir

—  C. Yielding chemical substance pesticide purpose, oil spill of tanker's ship

THE IMPACT FROM WATER POLLUTION

v A. Water sacrilege by indigenous inorganic chemistry material plant manure:

}  - if its luxuriant purpose and its imprecise discharge can contaminate river, lake, accumulating basin, and oceanic and another water source

v B. Water sacrilege by inorganic chemistry material as sour as, salt, and metal:

}  - Indecent water to be drunk

}  - downing food plant production

v C. Water sacrilege by organic chemistry material that as oil, pesticide, detergent:

}  - Can kill fish and thes living one other being at water

v D. Eutrofikasi's happening Which Is waste which contain nitrate and ingoing phosphate goes to waters can cause excessive growth on algae.

SOIL POLLUTION

—  Soiled pollution is polutan's input earth into soiled so gets to down earth quality

SOIL POLLUTION

}  Pollutan:

}  ~ Household waste (garbage)

~ Industrial waste

~ Agricultural waste

~ Waste market

}  Impact:

}  ~ Kill microorganisms (decomposing), Animals, plants

~ Dumping heavy metals into the soil (at random) will contaminate the soil

~ Heavy metals can damage nerves and cause defects in the offspring of organisms

}  How to Handles:

}  ~ Every household should be easy to sort out the garbage decomposes a difficult decomposed

~ Every household should recycle the waste that can be described

~ Every person should have to throw trash in the appropriate fields

ENVIRONTMENTAL POLLUTION

 Environtmental polution is The entry of materials into the environment that can interfere with living organisms in it. contamination occurred either naturally or due to human action.

—  All life being result waste who can be recycled by physical process. but then, if resulting waste more a lot of and not in proportion to process runaway speed recycles will happen environment pollution.
