Chemical Pesticides - A Potential Environmental Threat
By:- Iqra Ahmed
Chemical pesticides are
being used in Pakistan for years and we clearly know its benefits but what we
don’t know is how harmful use of chemical pesticides is to human health.
Pesticides are designed to kill fungus, plants or animals that feed on crops. Chemical Pesticides are dangerous because they
contain Persistent Organic
Pollutants (POP’s). They’re called
persistent because they are not easily removed from the environment.
Pesticides transfer in the
environment from the various ways. They:
·
Are carried by the wind
·
Leave residues on product
·
Remain inside produce and animals
·
Run off into open water, contaminating public water supply as well
as fish and other seafood
Chemical Pesticides can cause: brain disorder, skin irritation,
cancer, fatigue and many other problems.
Therefore, we should try to find a better alternative for chemical
pesticides rather than risking our health and life. One of the best alternative
is the use of biological pesticides. They can be
developed using fungi, bacteria, and other organically present substances. Some
biological pesticides are microorganisms that, without any manipulation,
demonstrate natural effectiveness in targeted pest control. These generally
aren’t toxic to humans or animals and don’t leave a persistent residue.
