Deforestation is the removal of a
forest where the land is thereafter
converted to a non-forest use.
Deforestation occurs for many
reasons:

Air Land Water
Smog

Air Pollution

Water Pollution

Land Pollution

ENERGY INDUSTRY
The environmental impact of energy harvesting and
consumption is diverse.

 Coal mining and burning
 Electricity generation
 Nuclear power
 Oil shale industry
 Petroleum
 Reservoirs
 Wind power

OVERUSE OF NATURAL
RESOURCES
 the depletion of natural resources has
become a major focus of governments
and organizations such as the United
Nations.
The depletion is caused by
 Mining,
 petroleum extraction,
 Fishing,

AND NOT FOR

NEED OF
CONSERVATION
 Conservation biology is the scientific study of the
nature and status of Earth's biodiversity with the
aim of protecting species, their habitats, and
ecosystems from excessive rates of extinction.
 Habitat conservation is a land management

especially conservation reliant species, and
prevent their extinction, fragmentation or
reduction in range.
