Environment and human beings are too interlinked with each
other as we are part and parcel of it. As human beings are shaping
into super beings with help of science and technology in this process
new pollutants are invited into environment on regular basis.
We are just postponing and changing the dumping areas which
eventually occupying environment making more complicated to
clear. This means we are at high risk from those pollutants as they
are occupying in all levels as we are unable to sustain far with all
these dumping of pollutants. Environment is not advancing as fast
as pollutants to degrade them through natural process and retain
to normal condition. Products obtained from living organisms, have
simple mechanisms to dispose and degrade them into useful forms.
The dumping of nature as carbon deposits from millions of years
stored in earth, are now released again into atmosphere by us. If we
go on in this process, we will pay the price to our own acts. We know
this from the eve of origin of life i.e., 3.5 billion years ago with many
new combinations of chemicals and their fluctuations, kept many
organisms at bay. Cyanobacteria released oxygen approximately
2.5 billion years ago, as oxygen, which increased slightly become a
pollutant took its toll by killing many organisms. If we go through
five mass extinctions occurred in past, we can clearly see pollutants
are playing major role in creating disasters for living organisms. In
Ordovician-Silurian mass extinction, carbon dioxide was sucked
into rocks which caused glaciations causing many organisms death.
In late Devonian mass extinction, Sulphur dioxide occurred as
acid rains causing many organisms to perish. In Permian-Triassic
mass extinction also called great dying may be caused by release of
carbon dioxide, greenhouse gasses as methane which lead to global
warming which indirectly lowered oxygen levels leading to mass
extinction. In Triassic-Jurassic mass extinction, carbon dioxide
levels were quadrupled making the mighty dinosaurs to death. In
Cretaceous-Paleogene mass extinction, most of the species wiped
out due to increase of components like Sulphur. From the above we
can figure out if pollutants not treated, they will take their price
wiping out organisms how mater big they are without showing
mercy or forgiving. Now it’s necessary to think and analyze how
vulnerable we are to fight with pollutants. It is need of hour to find
new solutions to clear pollutants with help of our co-organisms like
plants and microorganisms to battle with pollutants. It is well known
truth that microorganisms are used from dawn of humans, for our
own benefits in food and spread it to medical applications, now we
are extending them to degrade the pollutants. Microorganisms are
living biotechnology laboratories which are boon for human race
to modify and use them. These little soldiers can be genetically
modified and use them for just to degradation of pollutants at
all levels. They had lived through very harsh environment from
their origin and have a great deal in using some of the pollutants
as their substrates. Already there are so many microorganisms
involved in bioremediation and biodegradation process, in these
lines microorganisms should be used within control to protect us
from the pollutants. We need to prepare not only for to clean up our
pollutants but also be ready to clear any type of pollutants when
occurred abruptly.
There should be many discussions and debates on the
environment issues through which innovations and new findings
will come out, without discussions and also without proper
guidelines there will be more harassment to health of environment
which ultimately takes it wrath on humans. We should now build
up for living in this world with sustainable development and the
scientists should focus on the environment pollutants to dispose
them fast without much suffering of the environment. The
advancements of Science and technology can’t be sopped as that’s
what makes the humans to survive with less energy and happily
comfortably but with this, we should also make new discoveries for
the pollutant disposal.
