CONCERNS AND PROBLEMS

ANOXIC WATER

HypoxiaOcean deoxygenation

- Areas of seawater or freshwater that are depleted of dissolved oxygen

-Significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years- a change in average weather conditions or the distribution of events around that average

Global warming

Global dimming

CLIMATE CHANGE

CONSERVATION

Coral bleaching

Poaching

- An ethic of resource use, allocation and protection

ENERGY

Renewable energy

Efficient energy use

ENVIRONMENTAL DEGRADATION

Eutrophication

Habitat destruction

-Deterioration of the environment through depletion of resources any change or disturbance to the environment perceived to be deleterious or undesirable

ENVIRONMENTAL HEALTH

Electromagnetic radiation

Lead poisoning

- Branch of public health that is concerned with all aspects of the natural and built environment that may

affect human health

GENETIC ENGINEERING

Genetic pollution

Genetically modified food controversies

- Direct human manipulation of an organism’s genomeusing modern DNA technology

INTENSIVE FARMING

IrrigationSlash and burn

- An agricultural production system characterized by the high inputs of capital, labour, or heavy usage of

technologies

LAND DEGRADATION

Land pollution

Soil erosion

-Process in which the value of the biophysical environment is affected by one or more combination of

human-induced processes acting upon the land

LAND USE

Urban sprawl

Habitat destruction

- Involves management and modification of natural environment or wilderness into built environment such

as fields, pastures, and settlements.

Nanopollution

- Deals with developing materials, devices or other structures processing at least one dimension sized

from 1 to 100 nanometers

NUCLEAR ISSUES

Nuclear meltdown

Nuclear weapons

- Nuclear power debate is about the controversy which has surrounded the deployment and use of

nuclear fission reactors to generate electricity from nuclear fuel for civilian purposes

Overpopulation in companion animals

Tragedy of the common

OVERPOPULATION

- Condition where an organism’s numbers exceed the carrying capacity of its habitat

OZONE DEPLETION

CFC

-Steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere

much larger springtime decrease in stratospheric ozone over Earth’s polar regions

POLLUTION

Water pollution

Air pollution

- Introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem.

RESOURCE DEPLETION

Logging

Mining

- Economic term referring to the exhaustion of raw materials within a region

TOXINS
