The Green
Tabloid
Water, soil and Earth's green biosphere are the support system
for animal life on planet Earth. Plants are a part of the continuum of life,
where the important interactions of plants and animals occur. While both
herbicides and pesticides have been with us for decades, and provide us humans
with partial control over nature, the use of these compounds must constantly be
reconsidered to improve methods for reducing their harmful effects to living
beings in ecological food chains. Our garden hedges are homes for pollinating
butterflies, beetles, bees and dipteran flies. Many of these insects are
necessary for our cultivation efforts and the destruction of their homes remains
questionable. Similarly, herbicides may destroy fertile soils, and as much as we
would like to clear our gardens of weeds, the weeds are an indication of a
healthy, organic garden. Herbicides
and pesticides often end up in undesirable places in nature. Many toxic
chemicals also have a way of persisting in the environment, both in food and
water supplies for wildlife and humans.
A toxic
chemical, an insecticide or herbicide, may be sprayed or dusted onto crop
plants. The chemical may enter the soil or remain on the plant's leaves until
rain or irrigation washes the chemical further into ground-water, rivers and
oceans. While high concentrations of toxic chemicals seldom accumulate in the
hydrological systems, many compounds are found in higher concentration in fish
and waterfowl as well as human beings. All in all, caution is needed in the use
of pesticides and herbicides, while exploring alternative ways of keeping our
garden and crop plants healthy.
