Organic Agriculture
  • A Future Trend For Better Health And Environment

2
The birthright of all living things is health.
This law is true for soil, plant, animal and
man the health of these four is one connected
chain. Any weakness or defect in the health of
any earlier link is passed onto the next and
succeeding link, until it reaches the last,
namely, the man. Sir Albert Howard, 1945

What Is Organic Food?
  • Organic food is grown by organic agriculture in
    soil rich in organic matter called humus- the
    living part of the soil.
  • Humus contains billions of bacteria, fungi and
    other minute organisms that provide tremendous
    amount of minerals and other nutrients to the
    plants.

7
Organic agriculture
  • It is a sustainable farming system that produces
    healthy crops and livestock without damaging the
    environment.
  • It avoids the use of artificial fertilizers and
    pesticides and, relying instead on developing a
    healthy and fertile soil and growing a mixture of
    crops.

8
Human Health
  • Difficult to assess the effect an organic diet
    has on a persons health.
  • Small number of studies suggest the health effect
    of organic food.
  • On the contrary, abundant studies have shown
    negative effects of non-organic food and
    conventional farming.

9
Pesticide
  • Carcinogenic ( such as DDT that was banned in
    1973 in the US).
  • Over 400 chemicals are being regularly used in
    conventional farming to kill weeds, insects and
    other pests that feed on crops.
  • Some crops are being sprayed up to 16 times with
    36 different pesticides.

10
Organophosphates
  • The most dangerous pesticides.
  • The most widely used- account for about half of
    the pesticides used in the US.
  • Cheap cost and broad spectrum of uses.
  • 60 million pounds are applied annually.
  • 17 millions pounds non-agricultural purposes.

11
Organophosphates- continues
  • Very poisonous and were used in the World War II
    as nerve agents.
  • Reduce the ability of cholinesterase to regulate
    a neurotransmitter called acetylcholine.

12
Symptoms Of Cholinesterase Depression
  • Headache Dizziness
  • Muscle twitches Nausea
  • and weakness Stomach Pain
  • Shortness of breath Anxiety
  • Diarrhea Pinpoint pupils
  • Convulsion
  • Coma

13
Endocrine Disrupting Chemicals (EDC)
  • Also known as gender benders.
  • They may affect genes in a way similar to
    estrogen.
  • Small dose can affect the sexual characteristics
    of animals.

14
Food Additives- Food Colorings
  • Food colorings cause a range of health problems
    including
  • Allergic reaction
  • Headaches
  • Asthma
  • Growth retardation
  • Hyperactivity in children
  • Small risk of cancer and tumor is associated with
    Red No. 3.

Better Nutrition
  • Organic food is grown by organic farming that
    retains organic matter in the soil that provides
    the nutrients plants and crops need.
  • The conventional food lacks substantive
    nutrition.
  • Speedy growth with agrochemicals
  • Largely water filled

17
Comparison of Organic and Non-Organic Produce
  • Dry matter 26 Protein 12
  • Potassium 13 Manganese 28
  • Calcium 56 Nitrates 69
  • Magnesium 49 Phosphorous 6
  • Iron 290
  • Copper 34
  • Essential amino acids 35

18
Reduce Heart Attacks
  • Salicylic acid is responsible for the
    anti-inflammatory action of aspirin and helps
    combat hardening of the arteries and bowel
    cancer.
  • Salicylic acid is produced naturally in plants as
    a defense against stress and disease.
  • Average level of salicylic acid in organic food
    is 117 nanograms per gram compare to 20 nanograms
    per gram in non-organic food.

19
The Environmental Impacts
  • Prevent climate change
  • Less CO2 is produced with organic food because of
    the use of organic fertilizer instead of
    commercial fertilizer.
  • Less CO2 with organic food because it uses less
    energy than conventional farming.
  • Development of soil as a major carbon sink.

20
Water And Air Pollution
  • Groundwater supplies about 51 of the drinking
    water in the US.
  • About 25 of groundwater is contaminated.
  • Less than 2 of pesticides applied to crop reach
    the target crops by aerial spraying.
