The world around us as we know it has evolved over millions of
years. The genes, which thrive and procreate under existing
conditions become more abundant and only such organisms survive.
These organisms are thus labeled as "fittest" for survival. The
natural selection of the sturdiest and the best genes has led to the
evolution of animals culminating in the species of Homo Sapiens. And
now, we humans are tampering with this natural process by tinkering
around with genes, to come up with crops and animals tailored to our
needs.
Biotech companies with
funds backing them are interested in producing genetically modified
crops and animals. For example, some varieties of tomatoes are
injected with DNA from an arctic flounder, which makes the crop
withstand low temperatures. Growth hormones are routinely given to
pigs to enable them to grow faster and bigger. Seeds are being
modified so that they are insect resistant. That is, they do not
produce specific proteins, which attract specific insects: crops of
cottons have been made in this way. The list is endless and getting
bigger every day. |
