We
have changed Earth in fundamental way. The physical feature of Earth is changing
rapidly. The hospitable Earth that we know is gone. We are now on dangerous Eaarth
-a dystopian reality. We have warmed the
planet, warm air holds more water vapor than cold, it rains harder and evaporate
faster. With sea ice melting, the albedo, or reflectivity, of arctic changes as
the mirror of white ice replaced by sun absorbing blue. Global temperature, heat
wave, rainfall, landslides, forest fires…have increased dangerously. Thunderstorms,
cyclones/hurricanes, lightning are more frequent and last longer. Methane chimneys
are opening up rapidly heating the planet further. The great rainforests are
dying. Plant yields and nutrition are falling, life giver phytoplankton are
dying, species are vanishing, biomass reducing and resilience of biodiversity
is falling. Oceans are acidifying, incapable to hold carbon nor sustain diverse
life, coral reefs are barren. Bacteria, parasites, algae blooms flourish, water
and mosquito borne diseases increase and spread. Extreme catastrophic events
are leading post-traumatic stress disorder, depression and variety of phobias,
and increased numbers of refugees. Add to it, warmer world is predicted to lead
to more wars and discords over shared water, rivers and arable land, violent
storms can even topple weak governments. The terrifying reality of end of cycle
of growth that institutions are hinged on. We don’t know how to regrow rain
forests, defreeze arctic, recreate ecosystems…
This
is what this book eaarth: making a life on tough planet (by Bill
McKibben) is dealing with, it was written almost 15years back -and that
surely is life time back in fast changing world, but still is valuable. As we see
climate catastrophes unfold on daily basis, and realtime vanishing of life nurturing
planet, these books provide insights. As for me it really didn’t add much to
the knowledge on these issues as I have kept abreast with unfolding reality and
have read much of the literature and documentaries on climate catastrophe. Unlike
15years back it is criminal to be not aware of these critical matters. There
are some mentions in the book that I found interesting, like for instance, this
collateral of climate catastrophe in Mozambique presenting unseen unexpected complexities
of changing world compounding problems for common people who really haven’t contributed anything
to these disasters that is enveloping their life: “…record rains in Mozambique
washed out huge quantities of land mines that were planted during brutal civil
wars. People, escaping flood, swam into these fields and were killed. To make matter
worse…thousands of dollars were spent to map the location of these minefields…some
even washed up on local beaches around the lake. Farmers are terrified to
plough their fields again because they don’t know what is under the silt”
