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

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

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.

CROPS

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

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
