Deforestation Temperate
and coniferous forests are generally carefully managed and are quite
quick to regrow. Rainforests take longer to grow and occupy a more
fragile environment. They are also destroyed at an alarming rate as
people sell the wood and clear land for housing, crops and industry.
Desertification
The spread of deserts threatens over a third of the world's land surface.
Drought A lack of rainfall over a long
period. They are specially likely where the climate is dry and variable.

Earthquake The
shock from an earthquake spreads out from a point known as a epicentre.
The amount of damage depends, among other things on the depth of the
epicentre. link I, link

Ecosystems
Energy We depend on
energy for almost everything we do. Fossil fuels - coal, oil and gas -
provide most of the worlds energy but they are also responsible for
major environmental problems.

Food
/ Nutrition There
is enough food to feed all the people in the world. Yet one person in
five suffers from serious hunger.
Forest
canopy The
forest canopy, as yet to be fully explored, must be protected because:
it's the home of most of the world's species, it's where animals find
much of their food, many human medicines are still to be found there, a
clean, breathable atmosphere depends on it, life on the ground is
interconnected with life above

Global
Warming & Rising Oceans Evidence
is accumulating that global warming, induced by fossil fuel use, is
becoming a real threat: temperatures have been at a record high for a
decade, coastal shorelines have retreated, island nations are losing
habitable land, glaciers are melting on five continents

Some steep mountain slopes are covered by soil-material. Heavy rain can
make earth unstable. In other cases erosion causes dangerous
