[Terrapreta] Polar cities

[Sean K. Barry]

Hi Dan Bloom,

Polar Cities is an interesting concept.  Hopefully the need for them won't 
be as dire as you predict; with a World War III Global War and all.  I 
suspect many hundreds of millions of people will need to migrate and 
possibly billions will die as a result of global climate changes and species 
loss.  Strife over climate devastation is highly likely.  Perhaps wars can 
be avoided with cooperative efforts.

We want to keep the world agricultural production as viable as possible.  We 
will need as much arable soil as possible.  We will possibly need more honey 
bees to do more pollination and/or plant and seed stocks to survive climate 
change.  We will need to be able to grow enough food crops to feed more 
people.  Where and how we live and survive will need to change some.

My son sent me an E-MAIL the other day with this attached message ->

http://www.alternet.org/workplace/67138/?page=1<http://www.alternet.org/workplace/67138/?page=1<http://www.alternet.org/workplace/67138/?page=1<http://www.alternet.org/workplace/67138/?page=1>>.

When the worlds poor are forced to move to higher ground or cooler climes, 
then they will need food and jobs.  We need an agronomic world wide 
revolution that re-combines food production with climate and soil mitigation 
work.  Many GREEN jobs will need to be done by many 100s of millions 
immediately and/or billions of people later to effect a correction for past 
human activity (burning fossil fuel).  The agrarian model needs to be 
maintained just to feed our billions of people.  The world climate zones are 
going to absolutely change, no matter what.  Adaptation, then, is the key to 
human survival.  Humans can make changes for improvement and repair the 
environment, with jobs for the poor and get them food.  This is I think what 
the promise of Terra Preta holds forward most.

Current industrial agricultural practices cannot continue as they are. 
There is great dependence on fossil fuel based fertilizers, herbicides, and 
pesticides.  Natural methods will need to be employed, as the fossil fuel 
sources will first become very expensive and eventually run out.  It is 
possible to make currently designed industrial fertilizers, herbicides, 
pesticides out of biomass biochemical sources.  When doing this is less 
expensive than doing it with fossil fuel based petrochemicals, then this is 
how it could be done.

Availability of fresh water on arable land is the other very important and 
changing set of requirements.  Both are undergoing large stresses and some 
losses, in scattered areas worldwide.  Global warming may increase 
atmospheric moisture levels (average relative humidity) in some areas and 
reduce other areas to drought and desert.

Terra Preta soils have a capacity to store nutrients, retain water, and 
maintain prolonged soil fertility.  If the Biosphere of living plants, 
animals, and microorganisms can maintain the atmosphere, then TP can promote 
the growth and health of our best efforts to maintain the atmosphere.  Terra 
Preta formation is a tool we can use to join with the natural systems and 
help maintain soil and atmospheric balances for living things.

Reducing fossil fuel use is imperative.  The CO2 and other emissions are at 
toxic levels and rising fast.  We should change immediately over to more 
renewable energy sources, including biomass, solar, geothermal, and wind, 
plus use nuclear instead of coal for the energy we need.  The developing 
"Third world" energy consumption should be supplied as much as possible from 
renewable sources.  I think this could modify the rest of the world's energy 
practices more effectively and less expensively than any other strategy.

Look at the Terra Preta site for information about its possible use as a 
soil fertility improvement strategy and as a carbon sequestration strategy 
at the same time!
