Definition
  • Genetically modified crops (GMCs, GM crops, or
    biotech crops) are plants, the DNA of which has
    been modified using genetic engineering
    techniques, to resist pests and agents causing
    harm to plants and to improve the growth of these
    plants to assist in farmers efficiency.

POSITIVES
13
GM crops are better adapted to specific
environmental conditions
14
GM crops need less herbicides and pesticides
15
GM crops produce bigger yields than non-modified
crops
16
Food of GM crops is safe to eat
17
GM crops result in tastier products
18
CONS
19
Taste of GMC are not as good or natural
20
New super weeds are coming up, which are also
more resistantSUPERWEED a hybrid plant that
contains genes for herbicide resistance produced
by accidental crossing of genetically engineered
crop plants with wild plants.
21
The safety of the products is not verified
yet.We are the test rats to test the safety of
GMCs. It has not yet been proven.
22
A genetically modified ingredient can cause
cancerIt was brought to attention that food and
water contaminated with genetically engineered
material could increase the growth of malignant
tumors upon contact with humans. Later, other
studies suggested a link between engineered food
and cancer.
23
You are not what you eat anymoreGenetic
engineering allows introducing animal products in
plants which could raise issues for those with
dietary restrictions, like vegetarian or
vegans.
