Basic for carbohydrates,protein, fats
CO2 released = CO2removed from Atm
Released
CO2 respiration
Fuel burning
Decay process

Source of Pollution
Combustion of fossil fuel
Incomplete :
Disposal of by products, wastes, toxic substance
Ni, Hg, Cd,Pb-factories, effects on nature
Excessive chemical fertilizers, fungicides,
pesticides i.e. nitrates & phosphates
Other:
Emission ofnoise , smoke &poisonous gasfrom vehicles &machineryDisposal ofrubbish i.e.plastic ,leftoverfood & solidsubstanceDisposal ofsewage

OZONE(O3)
Located in stratosphere (15-30KMfrom earth)
Absorbs most of UV light & protectsliving things on earth
Sunburn is due to UV rays that arebeing absorbed by plant and animaltissues.
CFC damages ozone by breaking it intochlorine radicals
Effects

Why SmaNaturalResources
Managem
Logging
Control number of trees to be cut down
Ensure surrounding trees are not affected
Fishing Industry
No oil spillTotal Allowable Catch-limit number of fish per fisherman
Mining Industry
Proper chemical non -toxic
Convert unused mining field to recreation park
Clearing Land
-proper drainage system
