DEFORESTATIONDEFORESTATION

Deforestation is the removal of a forest where the land is thereafter converted to a non-forest use.

Deforestation occurs for many reasons:

used or sold as fuel,

used as pasture for livestock,

plantations of commodities,

Settlements etc..

OVER-POPULATIONHuman overpopulation occurs if the

number of people in a group exceeds the carrying capacity of a region occupied by that group.

WASTEWaste and wastes are terms for unwanted materials.

Examples include

municipal solid waste (household trash/refuse),

hazardous waste,

wastewater (such as sewage, which contains bodily wastes,or surface runoff),

radioactive waste, and others.

POLLUTION Pollution- adding harmful substances or products into the

environment

The use of fossil fuels is the major cause of pollution

ENERGY INDUSTRY

Biodiesel Coal mining and

burning Electricity generation Nuclear power Oil shale industry Petroleum Reservoirs Wind power

The environmental impact of energy harvesting and consumption is diverse.

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,

Forestry etc..

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 practice that seeks to conserve, protect and restore, habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range.
