UNIT IV. ENVIRONMENTAL PROTECTION AND DISASTER RISK MANAGEMENT Flashcards
refers to everything that surrounds us. It includes the natural world as well as the things produced by humans.
Environment
is the study of how living things interact and depend on each other.
Ecology
is the symbiotic relationship between organisms and species within one particular area in which each depends on each other to support the continuance of life.
The ecosystem
Ecosystems are found in the various sections of the natural environment which include:
forests, deserts, grasslands, freshwater, marine areas, and even caves.
is a practice of protecting the natural environment on individual, organization controlled or governmental levels, for the benefit of both the environment and humans.
Environmental Protection
is an ideology that delves into the importance of natural resources. This ideology speaks on the indispensability of the environment that destruction of the latter would impede or stop development. Furthermore, the ideology claims that environmental protection is a must for everyone’s survival.
Environmentalism
likewise states that environmental protection can go hand in hand with sustainable development.
Environmentalism
Causes of Environmental Degradation
- Migration
- Industrial growth
- Population growth
- Use of modern technology
- Natural resources utilization
gases released primarily, traps the sun’s heat and prevents it from radiating back into space.
The carbon dioxide (also methane, nitrous oxide, perfluocarbons, and sulfur hexafluoride), greenhouse gases
Other Impacts of Climate Change
- Water scarcity
- Reduction in food production
- Disease problems
- Mass extinction of species.
- Sea level rise
- River flooding
The loss or acquisition of a particular trait including changes in the genetic characteristics due primarily to the changes in the environment and unequal survival or reproduction of certain species.
Evolution by Natural Selection.
Two or more species evolve in response to each other
Co-Evolution.
The irreversible disappearance of a population or species due mostly to the destruction of natural habitat and the loss of sources of nourishment.
Extinction.
is a damaging or destructive event that causes serious loss, destruction, hardship, unhappiness, or death.
Disaster
either brought by nature or those that can be attributed to people are everybody’s concern.
Disasters
the rising of water level in a particular area which results from a very high volume of rainwater and the lack of an efficient drainage system or a relief system that will drain the excess water.
Flood
is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth’s lithosphere that creates seismic waves
Earthquake an earthquake (also known as a quake, tremor or temblor)
can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities.
Earthquakes
is also used for non-earthquake seismic rumbling.
. The word tremor
any seismic event — whether natural or caused by humans — that generates seismic waves.
earthquake
are caused mostly by rupture of geological faults, but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests.
Earthquakes
An earthquake’s point of initial rupture is called its .
focus or hypocenter
is the point at ground level directly above the hypocenter.
. The epicenter
It involves the destruction of properties and loss of lives due to intense heat brought about by fire.
. Fire.
These are armed encounters between aggressive, hostile, and lawless elements.
. Civil Unrest and Armed Conflict.
A storm system that produces strong winds and torrential rain
Tropical Cyclone.
feed on heat released when moist air rises, resulting in condensation of water vapor contained in the moist air.
Cyclones
is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems (such as tropical cyclones and strong extratropical cyclones), the severity of which is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides.
A storm surge, storm flood or storm tide
during which lava, tephra (ash, lapilli, volcanic bombs, and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists.
Volcanic Eruption
which involve the decompression of gas within magma that propels it forward.
magmatic eruptions,
are another type of volcanic eruption, driven by the compression of gas within the magma, the direct opposite of the process powering magmatic activity.
Phreatomagmatic eruptions
which is driven by the superheating of steam via contact with magma; these eruptive types often exhibit no magmatic release, instead of causing the granulation of existing rock.
phreatic eruption,
A chain of fast-moving huge waves commonly caused by the eruption of underwater volcanoes, earthquakes, or even the impact of meteorites.
Tsunami.
refers to several forms of mass wasting that include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows and debris flows.
Landslide
Landslides can occur underwater, in which case they are called ____ and in coastal and onshore environments
submarine landslides
The outbreak of diseases involving a large volume of the population in a certain area. This unfortunate event may occur from lack of clean water, lack of or inadequate health services, and the lack of awareness in preventing diseases.
- Epidemic.
This is a condition in which the soil dries up, commonly caused by intense heat and the absence of rainfall.
Drought.
Originating from ordinary combustible materials which can be extinguished by cooling commonly with the use of water.
Class A.
Originating from a flammable and combustible liquid which can be extinguished by removing the oxygen or fuel. Chemical agents, wet cloth, sand, and soil are usually used for this class of fire.
Class B.
Originating from electrically charged or mechanical devices which can only be extinguished by removing the oxygen or fuel. Dry chemicals, sand soil, and similar approaches are used to prevent further damage like electrocution.
Class C.
WHAT TO DO IN CASE OF FIRE
S – Sound the alarm
A – Advise the fire department (local emergency numbers)
F – Fight the fire
E – Evacuate
Everything that surrounds us. It includes the natural world as well as the things produced by humans.
ENVIRONMENT
The study of how living things interact and depend on each other.
ECOLOGY
The symbiotic relationship between organisms and species within one particular area in which each depends on each other to support the continuance of life. It is composed of the living and non-living components. Ecosystems are found in the various sections of the natural environment which include: forests, deserts, grasslands, freshwater, marine areas, and even caves
ECOSYSTEM
The practice of protecting the natural environment on individual, organization controlled or governmental levels, for the benefit of both the environment and humans.
ENVIRONMENTAL PROTECTION
The ideology that focuses on the importance of natural resources. It advocated the need for man to live in harmony with nature to prevent the life-sustaining environment it encourages individuals to change the lifestyle that I disruptive of the natural functioning of mother nature and to adopt programs and measures for protecting the environment and pursue a development program that is sustainable and environmentally friendly.
ENVIRONMENTALISM
The destruction of environment.
ENVIRONMENTAL DEGRADATION/
DESTRUCTION
the commission or omission, by a person having capacity, of any act, which is either prohibited or compelled by law, and the commission of which is punishable by a proceeding brought in the name of the government whose law has been violated.
CRIME
an act to be done in order that a crime could not happen.
CRIME PREVENTION
The outbreak of diseases involving a large volume of the population in a certain area. This unfortunate event may occur from lack of clean water, lack of or inadequate health services, and the lack of awareness in preventing diseases.
EPIDEMIC
This is a condition in which the soil dries up, commonly caused by intense heat and the absence of rainfall. Drought makes it difficult for the soil to support the plants and other living organisms that depend on it.
