The document discusses numerous environmental issues, concerns, and problems including: 1) Climate change, ocean deoxygenation, coral bleaching, and pollution from activities like poaching, intensive farming, and urban sprawl which are degrading the environment. 2) Issues related to energy usage like ensuring access to renewable and efficient sources of energy. 3) Public health problems caused by environmental factors such as electromagnetic radiation, toxins from activities like mining, and genetic engineering technologies and their potential impacts.

1. ENVIRONMENTAL
ISSUES,
CONCERNS AND
PROBLEMS

2. ANOXIC WATER
Hypoxia
Ocean deoxygenation
- Areas of seawater or freshwater that are depleted of
dissolved oxygen

5. -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

7. CONSERVATION
Coral bleaching
Poaching
- An ethic of resource use, allocation and protection

9. ENERGY
Renewable energy
Efficient energy use

11. 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

13. 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

15. GENETIC ENGINEERING
Genetic pollution
Genetically modified food
controversies
- Direct human manipulation of an organism’s
genomeusing modern DNA technology

17. INTENSIVE FARMING
Irrigation
Slash and burn
- An agricultural production system characterized by
the high inputs of capital, labour, or heavy usage of
technologies

19. 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

21. LAND USE
Urban sprawl
Habitat destruction
- Involves management and modification of natural
environment or wilderness into built environment such
as fields, pastures, and settlements.

23. NANOTECHNOLOGY
Nanotoxicology
Nanopollution
- Deals with developing materials, devices or other
structures processing at least one dimension sized
from 1 to 100 nanometers

25. 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

27. Overpopulation in companion animals
Tragedy of the common
OVERPOPULATION
- Condition where an organism’s numbers exceed
the carrying capacity of its habitat

29. 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

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

33. RESOURCE DEPLETION
Logging
Mining
- Economic term referring to the exhaustion of raw
materials within a region

35. TOXINS
Pesticides
Herbicides
- A poisonous substance produced within living cells
or organisms

37. WASTE
Electronic waste
Medical waste
- Unwanted or useless materials
