Many behaviors are

Part 9:
Planet Under Stress
Review
Human activity can upset the balance of ecosystems, leadng to the decline of many
species,
primarily due to
loss
and
destruction.
Extinction is a fact of
life,
but the current rate of the loss of species is accelerating, due to three main
factors:
overexploitation
introduction of
species.
pollution can have devastating effects on animals high on the food
chain
due to
biological
.
The burning of coal releases
into the
atmosphere,
causing
precipitation.
Atmospheric pollution also includes
(CFCs), which can deplete the
layer.
The burning of
fuels releases
dioxide into the
atmosphere,
leading to global
due to the
effect.
One alternative source of energy is
power, but this has its own
drawbacks
such as
operation
and waste disposal.
The root of environmental problems is the rapid growth of the
population.
Preserving biodiversity efforts include
restoration
breeding to increase

of
ecosystems.
There are environmental success stories, where one or a few
individuals
made a difference.
