MINERAL RESOURCE
S
INTRODUCTIONThe world is now thought to be about 4.55 billion years old,
just about one-third of the 13.75-billion-year age
estimated for the universe.Birth rate:
19.15births/1,000 population (2011)
Death rate: 8.12 deaths/1,000 population
(July 2011)
MINERAL RESOURCE
It is the class of non-renewablefinite natural resourcesolid inorganic substancesCharacteristic crystalline form Homogeneous chemical composition
Is ice a mineral?....
Although liquid water is not a mineral, it is a mineral when it freezes. Ice is a naturally occurring, inorganic solid with a definite
chemical composition and an ordered internal structure
Mineral Uses
Metallic
Iron Building industrial uses
Copper Alloys,electrical products
Gold Jewellery,Monetary purpose
Titanium Aircraft
Non-Metallic
Salt Metallurgy,chemicals
PotassiumSulphurAsbestos
Chemicals,fertilizersIron & steel industry,acidRoofing,insulation
ADVERSE EFFECTS
• 40% of mining area is for waste disposal• Deforestation• Degradation of land• Air pollution due to emission of dust &
gases• Rehabilitation of affected population like
tribals• Adverse impact on historical monuments
RESPONSES TO LIMITED AVAILABILITY
Find more sources Find substitute Recycle Use less & make more efficient use of what
is available
FOOD RESOURC
ES
INTRODUCTION
It is 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.

Domestic animal are an important food source.Eg:- milk,meat
LIVESTOCK
Aquaculture
• Aquaculture-where fish and shellfish are raised for food• Supplies 20% of world’s commercial food harvest• Fish & sea food contribute up to 1/2th of animal protein
UNDERNUTRITION
• Undernutrition-Consuming
insufficient food to meet
one’s minimum daily energy
requirement for a long enough time to cause harmful effects
MALNUTRITION
• Malnutrition-Faulty nutrition. • Caused by a diet that does not supply a persons with
enough protein, essential fats, vitamins, minerals and other nutrients
Diseases Maramus-lack of protein & calories. Kwashiarkor-lack of protein
• learning disability• failure to neural development
OVERNUTRITION
An excessive intake of food, especially fats

Case study• Endosulfan, a highly toxic organochlorine
pesticide• (1978-2001 ) regularly 3 times per year in the
cashew plantations in Kasaragod • As early as 1979, new born -calves stunted and
deformed limbs • By 1990s serious health disorders began.• Children - mental retardation, physical
deformities etc. • Men and women-chronic ailments
