-
vast variety of life forms in entire earth.
Biodiversity
-
encompasses all kinds of life forms,from the single-celled organisms to largest multi-celled organisms.
Biodiversity
-
source of essential goods & ecological services that constitute source of life for all
Biodiversity
-
people will always depend on this on the wholeness of our being & everyday lives.
biodiversity
-
has direct consumptive value in food,agriculture,medicine & industry
Biodiversity
-
- Understanding biodiversity within the concept of __ needs a through study on the relationship of the biotic and abiotic
ecosystem
-
living organisms
Biotic -
-
nonliving organisms.
Abiotic -
-
is needed to study the ecosystem.
Interdisciplinary approach
-
3 Ways & processes in the ecosystem that are not apparent nor appreciated by us human beings.
- need to drink clean and fresh water
- need to eat healthy vegetables and food
- need of man to transport makes him rely on fuel.
-
Significant decline in biodiversity has direct human impact in:
physical & social need of human beings.
-
Changes in the ecosystem affect: 4
- livelihood
- Income
- Occasion
- May even cause political conflict
-
could have erratic effects on marine life & human beings
Changes in biodiversity
-
5 Major Threats by UN' Environment Programme
- Habitat loss and destruction
- Alteration in ecosystem composition.
- Over-exploitation
- Pollution and contamination
- Global climate change
-
Basic concept abt biodiversity loss was from: 2
- Charles Darwin
- Alfred Russel Wallace.
-
major factor that contributes to sustainable food production for human beings.
Biodiversity
-
Almost all living organisms are dependent to their environment to live & reproduce.
Health, Biology and Biodiversity
-
Basic needs of living organisms such as air, water,food,and habitat are provide by its environment.
Health, Biology and Biodiversity
-
The evolution of human beings was due to the improved access to basic needs.
Health, Biology and Biodiversity
-
Advances in agriculture,sanitation,water treatment,and hygiene have had a far greater imnact on human health
Health, Biology and Biodiversity
-
increase the risk of cancer, heart disease, asthma, and many other illnesses.
Environmental hazards
-
Environment-Related Illnesses (12)
- Parkinson's disease
- Asthma
- Cancer
- Chronic obstructive pulmonary disease
- Heart disease
- Obesity,
- Occupational injuries,
- Diabetes
- Arthritis,
- Dysentery,
- Malaria
- Depression.
-
could also have a serious impact on human health & deteriorate farming systems
Climate change
-
Issues of intersection of health & environment
pesticides play an important role in increasing crop yields, but they can also pose hazards to human health and the environment.
-
group w/ increased susceptibility to adverse effects of an environmental risk due to age,genetics & health status
Vulnerable subpopulation
-
Various public health strategies pit the rights of individuals against the good society: 4
- mandatory treatment
- vaccination,or diagnostic testing;
- isolation and quarantine;
- decease surveillance.
-
Different species of plants & animals & the places they live
Biodiversity
-
They give us food, clear water, crisp air, medicines & provide homes
Biodiversity
-
Biodiversity is like a
safety net
-
Rapid increase of population put pressure, threatening survival of natural species & habitats
Human population growth
-
Technological and industrial processes led to production of harmful to living things
Human population growth
-
Humans remove tress & other plant life from wide areas of their natural habitat
Destruction of habitat
-
Activities that have effect of displacing plant and animal , Humans drained, filled or redirected wetlands, ponds, streams & other habitats
Habitat destruction
-
allowing large number of domestic animal to graze an area too small to support them
Overgrazing
-
Failure to allow soil to recover nutrients
Overcropping
-
Removing plants from the ecosystem for their economic value, This removal decrease biodiversity
Direct harvesting
-
2 Signs of environmental contamination
- Deformation of illness
- Death of natural populations
-
Ex of environmental contaminants: 4
- Reproductive cycle disruption in birds
- Death & population decline of birds and fish
- Death and disorientation of marine mammas
- Contaminated water
-
Ex in humans 4
- Chronic lung disease
- Asthma
- Cancer
- Birth defects
-
Fuels obtained from underground deposits, Burning this fuels linked to global warming
Fossil fuels
-
Results from combining sulfur & nitrogen oxide iomns
Acid precipitation
-
is considered historic period in 21st century characterized by its rapid shift from traditiinal history
information age
-
information age is also called
computer age
-
refer to people info society the birth of electronic info
information age
-
father of info age
claude shanon
-
passing of traits from parents to offspring
heredity
-
the genetic make up
genotype
-
the physical characteristics
phenotype
-
measure of how ofteb a disease genotype correlates
penetrance
-
involves altering gens inside body cellls
gene therapy
-
heredity factors is known as
genes
-
pair of genes that exercise parallel control over same trait
allele
-
is pased from gen to gen and act as genetic factor
DNA
