Forests used to act as cabon sinks and a state of approximate
equilibrium was maintained. Deforestation contributes to global
warming in a couple ways.

Im sure you meant "carbon" dioxide sinks and I agree. Every
green plant sucks up CO/2 and gives off O/2. And yes trees are
cut down,, but all logging companies replant. They arent going to cut
their own throats by not replanting.

A grove of softwood conifers is not nearly as efficient for storing
CO2 as an old growth, mixed forest.

But those confiers can store it up keep it in stroage in the from of
Buildings while growing and absorbing even CO2

In time the Pine can soak up and keep in storage in our home and
buildings a lot more co2 than the old growth forest can

''There are four components of carbon storage in a forest ecosystem.
These are trees, plants growing on the forest floor (understory
material), detritus such as leaf litter and other decaying matter on
the forest floor, and forest soils. Carbon is sequestered in the
process of plant growth as carbon is captured in plant cell formation
and oxygen is released. As the forest biomass experiences growth, the
carbon held captive in the forest stock increases. Simultaneously,
plants grow on the forest floor and add to this carbon store. Over
time, branches, leaves and other materials fall to the forest floor
and may store carbon until they decompose. Additionally, forest soils
may sequester some of the decomposing plant litter through root/soil
interactions.''
