Climate change has become a leading environmental
issue. It is now a challenge for the entire world.
Since we share one atmosphere, the effects of global
warming in one part of the planet are eventually felt
in other parts as well, and on all living species.
Given the predictions of the scientists and the erratic
climate phenomena being experienced by the people,
the human society is not only recognizing the damage
to the environment, but also finally accepting its
own role in disturbing the balance of nature.
The world leaders have been participating in several
conventions and conferences, and signing various agreements
and protocols in order to arrive at a global consensus.
Ultimately, not only do we need to prepare ourselves
to meet the impacts of climate change that we are
already facing, but also need to make some tough choices
with regards to - our dependence on fossil fuels for
energy, relentless consumerism, and continued exploitation
of the natural resources.
Energy crisis, acute shortage of food and water,
and threat of natural calamities loom large. Therefore,
there is an urgent need to find solutions â€“ not only
at the global, regional, and national levels, but
also at the local level, and most importantly, at
the level of the individual. Our survival will depend
on how we plan collectively and act individually.
