2. MINERAL
RESOURCES

3. INTRODUCTION
The 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)

4. MINERAL RESOURCE
It is the class of non-renewable
finite natural resource
solid inorganic
substances
Characteristic
crystalline form
 Homogeneous
chemical composition

5. 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

6. Mineral Uses
Metallic
Iron Building industrial uses
Copper Alloys,electrical products
Gold Jewellery,Monetary purpose
Titanium Aircraft
Non-Metallic
Salt Metallurgy,chemicals
Potassium
Sulphur
Asbestos
Chemicals,fertilizers
Iron & steel industry,acid
Roofing,insulation

7. 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

8. RESPONSES TO LIMITED AVAILABILITY
 Find more sources
 Find substitute
 Recycle
 Use less & make more efficient use of what
is available

9. FOOD
RESOURCES

10. 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, p
roteins, vitamins,
or minerals.

11. CROPS
Cultivated plants or
agricultural
produce, such as
grain, vegetables,
or fruit, considered
as a group: wheat &
rice are common
crop.

12. Domestic animal are
an important food
source.
Eg:- milk,meat
LIVESTOCK

13. 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

15. UNDERNUTRITION
• Undernutrition-
Consuming
insufficient food to
meet
one’s minimum daily
energy
requirement for a long
enough time to cause
harmful effects

16. 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

17. OVERNUTRITION
An excessive
intake of food,
especially fats

19. 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

20. HEALTH EFFECTS OF ENDOSULFAN

Out of the total identified
cases (4500)

disorders

Multiple congenital
disorders (including
skeletal deformities)
