Title: Organic Agriculture
1Organic Agriculture
- A Future Trend For Better Health And Environment
2The 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

6What 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.
7Organic 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.
8Human 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.
9Pesticide
- 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.
10Organophosphates
- 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.
11Organophosphates- 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.
12Symptoms Of Cholinesterase Depression
- Headache Dizziness
- Muscle twitches Nausea
- and weakness Stomach Pain
- Shortness of breath Anxiety
- Diarrhea Pinpoint pupils
- Convulsion
- Coma
13Endocrine 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.
14Food 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.

16Better 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
17Comparison 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
18Reduce 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.
19The 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.
20Water 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.
