industrial,
or by the release of a substances in the environment
or by any other human activity…
AND HUMAN IMPACT ON ENVIRONMENT
MEANS
HUMAN IMPACT ON ENVIRONMENT
FACTORS:Factors contributing to ENVIRONMENTAL LOSS
are: DEFORESTATION, OVER-POPULATION, WASTE, POLLUTION, OVERUSE/WASTAGE OF NATURAL RESOURCES, ENERGY INDUSTRY etc....
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.
IMPACT OF OVER-POPULATION
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.
Agricultural waste
Industrial waste
Domestic waste
POLLUTION Pollution- adding harmful substances or products into the
environment
The use of fossil fuels is the major cause of pollution
Air Land Water
SmogOzone DepletionAcid Rain
Solid wastesLandfills
Oil spillsfertilizers
Air Pollution
Water Pollution
Land 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..
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 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.
