These days, more people are growing organically, but that's
a trend, not a tradition.


I really can't let you say this Linz. For thousands of years we have
eaten our food grown entirely organically. Chemicals were introduced
in the 50s. Please, think about what you are saying.



not true, you are parroting a canard oft used by the organic lobby

The concept of pesticides is not new. Around 1000 B.C.E. Homer referred to
the use of sulfur to fumigate homes and by 900 C.E. the Chinese were using
arsenic to control garden pests. Although major pest outbreaks have
occurred, such as potato blight (Phytopthora infestans), which destroyed
most potato crops in Ireland during the mid-nineteenth century, not until
later that century were pesticides such as arsenic, pyrethrum, lime sulfur,
and mercuric chloride used. Between this period and World War II, inorganic
and biological substances, such as Paris green, lead arsenate, calcium
arsenate, selenium compounds, lime-sulfur, pyrethrum, thiram, mercury,
copper sulfate, derris, and nicotine were used, but the amounts and
frequency of use were limited, and most pest control employed cultural
methods such as rotations, tillage, and manipulation of sowing dates. After
World War II the use of pesticides mushroomed, and there are currently more
than 1,600 pesticides available and about 4.4 million tons used annually, at
a cost of more than $20 billion. The United States accounts for more than 25
percent of this market.
