L10: BIODIVERSITY AND HEALTH SOCIETY Flashcards
Is defined as the variety of life on earth.
biodiversity
It encompasses the diversity of genes within species,
the variety of species in a given area, and the
diversity of ecosystems.
biodiversity
A biological community of interacting organisms and their physical environment
ecosystem
Consists of abiotic and biotic components
ecosystem
large or small
ecosystem
The variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable
biodiversity
Only contains biotic components
biodiversity
Always large
biodiversity
a geographic area where plants, animals, and other
organisms, as well as weather and landscape, work together to form a bubble of life.
ecosystem
It contains biotic or
living organisms, as well as abiotic factors, or non-living
components.
ecosystem
Components of Ecosystem
biotic and abiotic factors
- It is living and in general capable of reproduction.
Biotic Factors
Biotic Factors Examples:
animals, the plants, fungi and the microorganisms.
- it is the non-living components that shape its environment.
Abiotic Factors
Abiotic Factors Examples:
soil, temperature, light intensity, humidity of air, topography,
etc
could bring varied effects
Alteration
. Humans have affected biodiversity through a variety of activities,
including:
Deforestation, habitat destruction, and urbanization,
Threats to Biodiversity
- Habitat Loss and Destruction
- Alteration in Ecosystem Composition
- Over-Exploitation
- Pollution and Contaimination
- Global Climate Change
The basic concept about biodiversity loss was
from
Charles Darwin and Alfred Russell Wallace.
According to
biodiversity is a vital element
of a human being’s nutrition because of its influence to food production.
Biodiversity is a major factor that contributes to sustainable food
production for human beings. A society or a population must have
access to a sufficient variety of nutritious food as it is determinant of their health as human beings.
World Health Organization,
Biodiversity’s Impact on Human Health
- Food Security
- Medicinal Resources
- Disease Regulation
How these three related to each other?
biology - health
biodiversity - health
biology - biodiversity
Negative effects due to Biodiversity Loss
- Increased Extinction Rate
- Human-Wildlife Conflicts
- Loss of natural balance that will lead to increase of
disease outbreaks - Loss of ecosystem services
Environment-Related Illnesses
- Food production causes environmental damage
(using of insecticides and pesticides) - Climate Change
- Using of fertilizers on crop
vertebrates fell into how many percentage from the 1970s due to human causes?
60%
general director of wwf international, described that the disappearance of wildlife is at an unprecedented rate
Marco Lambertini
Major contributing factor is the inhabitation of human beings and the use of land for economic gains.
Habitat loss and destruction.
Alterations and sudden changes, either within species groups or within the environment, could begin to change entire ecosystems. Alterations in ecosystems are a critical factor contributing to species and habitat loss.
Alterations in ecosystem composition.
. Over-hunting, overfishing, or over-collecting of species can quickly lead to its decline. Changing consumption patterns of humans is often cited as the key reason for this unsustainable exploitation of natural resources
Over-exploitation
Biological systems respond slowly to changes in their surrounding environment. Pollution and contaminatior. cause irreversible damage to species and varieties.
Pollution and contamination.
Both climate variability and climate change cause biodiversity loss. Species and populations may be lost permanently if they are not provided with enough time to adapt to charging climatic conditions.
Global climate change.
the basic concept about biodiversity loss was from??
Charles Darwin and Alfred Russel Wallace
