introduction to environmental science Flashcards
what are the major environmental problems
resource depletion
pollution
loss of biodiversity
what is the difference between renewable resources and non-renewable resources (give examples)
renewable resources :
can be replenished within a human lifetime (solar energy, wind energy, biofuels, trees)
nonrenewable resources: replenished slowly (coal, oil, minerals)
a degradation or an undesired change in air, water, or soil that affects the health of living things
pollution
what is the difference between biodegradable pollution and nondegradable pollution
biodegradable pollution:
will break down naturally over time
nonbiodegradable pollution:
does not break down
it is the number of species on the earth is unknown but estimates to be in the tens of millions
loss of biodiversity
define biodiversity
the no. of different species present in one specific ecosystem
it is the study of our planet’s natural systems and how humans and the environment affect one another
environmental science
the environment includes all ____and ____ things with
which _____ interact.
living and non-living
organisms
what is the first step for solving environmental problems
understanding the interactions between the humans and the environment
it is a great deal of resources is needed to support the human population
resources depletion
issues made by human activities that affect the environment, causing disaster
global environmental challenges
what are some global environmental challenges
global warming
earthquakes
air quality
fresh water
deforestation
demography
biodiversity law
energy
volcanoes
epidemic disease
define extinction
complete loss of species, is a natural event that can be accelerated by human actions
Intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
science
the environment includes ____, ____, ____
biophysical
socio-cultural
politico-economic
it is a field of study that deals with the application of physical concepts and techniques to biological issue
biophysical
it is a broad range of social and cultural factors that affect attitudes, emotions, actions and eventually health results
socio-cultural
it is a field of study in political science and economics that examines how political system and control economic system
politico-economic
environmental sci is the process of ______ and ______ to develop skills and attitudes necessary to understand and appreciate the interrelatedness among man, his culture and biophysical surrounding
recognizing values
classifying concepts
envi sci is the _____ of how humanity interacts with _____ and the ____
interdisciplinary study
other organisms
non-living physical environment
what are the 2 main subgroupings under the interdisciplinary study of other organisms and non living physical environment
the life science (such as biology)
the environment sci (such as geology)
envi sci refers to the awareness of the ____ and _____ envi and perceives its relevance for real life situations. as well as identify problems and _____ of the envi to be improved in view of sustainable development
physical
cultural
environmental imbalances
environmental sci entails practice in ____ and ____ of code behaviour about problems and issues concerning environmental quality
decision making
self-formulation
what are the aim of environmental sci
Attitude
Skill
Awareness
Participation
Knowledge
Evaluate
what are the focus of environmental sci
Identify
Understand
Solve problems
true or false:
earth has limited resources to support human societies
true
true or false:
environmental problems are complex. they always have simple solution
false - they SELDOM have simple solutions
what are the importance of environmental science
realize the environmental problems are global
understand the impacts of development on the environment discover sustainable ways of living
efficient utilization of natural resources
understand behaviour of organism under natural conditions
shed light on contemporary concepts such as how to conserve biodiversity
understand the interrelationship btwn organisms in popu and C
learn & creat awareness abt environmental problems at local, national and international lvl
identify the science scenarios involved with environmental science:
a community decides to use coal for electricity, as it is the cheapest source available
economics
identify the science scenarios involved with environmental science: the coal must be mined from under the soil
geology
identify the science scenarios involved with environmental science:
the coal must be transported to the population center by road or rail
engineering
identify the science scenarios involved with environmental science:
when it is burned at a power plant, air pollution is released. some of the pollution is converted to acid in the atmosphere
chemistry
identify the science scenarios involved with environmental science:
this falls as acid rain somewhere downwind
meteorology
identify the science scenarios involved with environmental science:
this acid stresses plants by affecting their nutrient absorption
ecology
identify the science scenarios involved with environmental science:
laws are passed requiring the plant to install pollution scrubbers
politics
define sustainability
a sustainable system that can continue indefinitely without depleting any of the material or energy required to keep it going
ample forest were systematically cut for agriculture land, structural materials and to move large stone monuments.
deforestation led to ____ then led to ____ and ____ of fish and shellfish populations
soil erosion
water quality degradation and elimination
it is the amount of biologically productive land and water needed to supply the people in a particular country or area with resources and to absorb and recycle the wastes and pollution produced by such resource use.
ecological footprint
what is the percentage of pollution due to vehicular emissions
80%
how many filipinos are exposed to air pollution, with health cost & loss of income of ____
per WB, 18Million
7.6 billion pesos/ year
what did the philippines do to conserve and protect the natural forest
total log ban (prohibit the cutting/ removal of trees)
create a national anti-illegal logging task force (reduce illegal deforestation)

study of organisms and the environment interacting with one another
ecology
study of geology, soil science, volcanoes, and the earth’s crust as they relate to the environment
geoscience
it is the study of earth’s atmosphere. it analyzes the relation of the earth’s atmosphere to the atmosphere of other systems
atmospheric science
it is the study of changes chemicals make in the environment
environmental chemistry
examples of environmental chemistry
contamination of soil
pollution of water
degradation of chemicals
transport of chemicals
what are the 4 components that relationship focus on the interaction between earth
its water
its air
its living organism
dynamic interdependent
What does the ecological footprint measures
How fast we consume resources and generate waste
