Photosynthesis
In this process
carbon
is
sequestered
as much as
120
giga tonnes a year with about
610
being stored each year.
Carbon
fixation
: turning
co2
into living
organic
compounds that grow.
About
50 gigatons
of carbon is drawn into the
bio pump
each
year
but only a
small fraction
makes it to the
sea floor.
3

It would be the same

don’t be a
fool
Only
20
% of UK peat is not
degraded.
Over
190 billion tonnes
of
carbon
will be released by
melting permafrost.
