"The conventional food, in turn, is that as a sick organism is maintained by drugs" (CAMPANHOLA & VALARINI, 2001) To avoid the use of pesticides, there are two paths. The first is simply not applicable here-them plants and create other control mechanisms, such as caring meticulously plant ("grooming" pest or biological control) and using organic fertilizer, this action more expensive labor- works. Another way to avoid the pesticide is to make the plants already born pest resistant and thus obviate the chemical protection. That was the prospect that biotechnology has brought to agriculture, developing GM foods. See the survey data PG Economics. Table 5 The study "GM Crops: Economic and Environmental Impact - The First Nine Years", done by PG Economics (an independent consulting firm specializing in economic and environmental impact of farming technologies) and published this month in London, pointed out that the planting of GM crops reduced 14% in the area affected by agrochemicals in 18 countries that sell this type of food. According to the study of PG Economics, since 1996, GM crops have reduced by 6% volume spraying of agrochemicals in the world - the equivalent of 172.5 million pounds of pesticide.

Some scientists claim that a transgenic plant is a Genetically Modified Organism (GMO), a technique developed long ago in an attempt to improve the species, others however, say there is a big difference between a transgenic

"Konvencionalne hrane, pak, da je kao bolesnom organizmu održava se od droge" (CAMPANHOLA & VALARINI, 2001) Da bi se izbjeglo korištenje pesticida, postoje dvije staze. Prvi je jednostavno nije primjenjiva ovdje-ih postrojenja i stvoriti druge mehanizme kontrole, kao što su brige studiozno biljka ("grooming" štetnik ili biološka kontrola) i korištenje organskog gnojiva, ova akcija skuplji radno- radovi. Još jedan način da se izbjegne pesticida je da Biljke su već rođena štetočina otporan i na taj način izbjegla kemijsku zaštitu. To je mogućnost da biotehnologija donio poljoprivredi, razvoj GM hranu. Vidi podaci iz ankete PG ekonomije. Tablica 5 Studija "GM usjeva: Ekonomska i utjecaj na okoliš - prvih devet godina", učinio PG ekonomije (neovisna konzultantska tvrtka specijalizirana za ekonomske i ekološke utjecaja uzgoj tehnologije) i objavljena ovog mjeseca u Londonu, istaknuo je da je sadnja GM usjeva smanjuje 14% u području pogođenom agrokemikalija u 18 zemalja koje prodaju ovu vrstu hrane. Prema istraživanju Ekonomskog PG, od 1996, GM usjevi su smanjena za 6% volumena prskaju agrokemikalija u svijetu - u protuvrijednosti od 172,5 milijuna kilograma pesticida.

Neki znanstvenici tvrde da transgenetska biljka je genetski modificiran organizam (GMO), tehnika se razvila tako davno u pokušaju poboljšanja vrste, drugi, međutim, tvrde da postoji velika razlika između transgenetska
