Why Organic Food Is Better For the Environment
Most people are aware that food that is grown according
to organic principles is free from exposure to many harmful herbicides
and pesticides, but that is only one small part of organic agriculture.
A larger part of organic agriculture involves the health of the
soil and the ecosystem in which crops and livestock are raised.
Organic practices recognize that a healthy, vibrant, and live soil
and ecosystems significantly benefit crops. When you garden organically,
you think of your plants as part of a whole system within Nature
that starts in the soil and includes the water supply, people, wildlife
and even insects. An organic gardener strives to work in harmony
with natural systems and to minimize and continually replenish any
resources the garden consumes.
Natural, undisturbed soil is alive with microbiotic
organisms which exist in harmony between the native plant life and
the inorganic minerals that provide the soil's substrate. When you
begin using herbicides, pesticides, and fast acting inorganic fertilizers,
you destroy the microbiotic activity, and soil becomes merely an
anchor for plant material, which requires constant input to continue.
Feed The Soil |
Feed The Plant |
- Soil fertility is a biological process
- Only the nutrients removed from the farm as crops need
to be replaced.
- Nitrogen is not purchased because it is supplied by symbiotic
and non-symbiotic processes.
- Inputs are purchased in their least processed and least
expensive form.
- 75 percent of the nutrient value of all feed consumed
by animals is returned in manure as nutrient input to the
farm.
|
- Soil fertility is an imported commodity.
- All nutrients required to "create" a crop are
purchased from off the farm.
- Nitrogen is a very important purchased input.
- Inputs are purchased in their most processed and expensive
form. Solubility and availability of these inputs is considered
a chemical process performed on an industrial level.
- All feed is a pure expense; animal manure is treated as
a problem rather than an asset.

Nonsustainable. |
In practice such systems have tended to avoid the
use of synthetically compounded fertilizers, pesticides, growth
regulators, and livestock feed additives. These substances are rejected
on the basis of their dependence on non-renewable resources, disruption
potential within the environment, and their potential impacts on
wildlife, livestock and human health. For example, synthetically
compounded fertilizers and pesticides generally suppress biological
activity in the soil. Some growth regulators and feed additives
are implicated in retarding the decomposition of manure and are
potential human health hazards. Instead, sustainable agriculture
systems rely on crop rotations crop residues, animal manures, legumes,
green manures, off-farm organic wastes, appropriate mechanical cultivation,
and mineral bearing rocks to maximize soil biological activity,
and to maintain soil fertility and productivity. Natural, biological,
and cultural controls are used to manage pests, weeds and diseases.
Why Buy Local Produce
- Local markets support local growers and local networks
- Fresh local produce can be easily traced to the fields in which
it was grown - that means safe and healthy eating!
Buying locally means that we do not have to transport food from
thousands of miles away which means less pollution and less road
congestion
- Local orchards are rich in wildlife and attract many species
- buying locally means we can keep orchards in business
- Often buying local market produce involves less packaging
- Buying produce in season is better for the environment. gives
better flavor and more enjoyment
Buy in Season
Different fruits and vegetables are available at
different times of the year due to the natural cycle of the season.
The spring, summer, autumn, and winter months all provide different
varieties of naturally grown produce. Buying fruit and vegetables
which are 'in season' helps to protect the environment because no
chemicals are needed to grow crops at times when they would not
otherwise naturally grow. Seasonal produce also provides year round
variety and flavor.
