Study Notes

Biodiversity and Healthy Society

Biodiversity encompasses the variety of life on Earth, encompassing species, ecosystems, and genetic variation.
It offers crucial benefits like food, medicine, and ecosystem services (pollination, water filtration).
Biodiversity supports ecosystem balance and resilience, which are essential for human life sustainability.
Loss of biodiversity threatens human health and well-being, as a healthy global environment is fundamental for human survival.
Protecting and sustainably using biodiversity can have significant health benefits for people.

Levels of Biodiversity

Genetic diversity: Variation in DNA sequences within a population.
Species diversity: Variety of species in a community.
Ecosystem diversity: Variety of habitats, communities, and ecological processes.

Genetic Diversity

Refers to the variation in DNA sequences within organisms.
Crucial for adaptability and resilience of populations.

Species Diversity

Quantifies the number of species in an area.
Reflects the biological diversity present in an ecological community.

Ecosystem Diversity

Describes the variety of habitats, communities, and ecological processes in an area.
A community comprises coexisting species, influencing each other.
An ecosystem involves living (biotic) and non-living (abiotic) components interacting within a geographic area, ranging in size.

Biodiversity Supports Food Security and Dietary Health

Genetic diversity in food systems is essential for crop development and food security.
Diverse diets promote health and prevent micronutrient deficiencies.
Loss of agricultural biodiversity threatens health, livelihoods, and food security.

Biodiversity and Medicine

Studying wildlife anatomy, physiology, and biochemistry aids in human medicine discoveries.
Examples include bears studied for osteoporosis, sharks for osmoregulation, cetaceans for respiration, and horseshoe crabs for ophthalmology.
Biodiversity supports both traditional and modern medicine sources for various communities.

Biodiversity and Infectious Disease Control

Loss of biodiversity and ecosystem change increase infectious disease risk in animals, plants, and humans.
Zoonotic outbreaks and pandemics are linked to human impact on biodiversity.
Understanding disease ecology is crucial to prevent negative impacts of disease control programs.

Connection with nature is essential for physical and mental well-being.
Reduction of anti-social behaviors in children is linked to environmental awareness.
Access to green spaces provides better health outcomes for patients in contrast to urban settings.

Threats to Biodiversity

Habitat loss: Human modification eliminates habitats vital for many species.
Overharvesting: Overexploitation of species for food or other resources reduces diversity.
Invasive species: Introduction of non-native species disrupts native ecosystems.
Climate change: Anthropogenic warming is a major risk, particularly combined with other threats.
Genetically Modified Organisms (GMOs): Potential risks include genetic contamination, competition with native species, and ecosystem impacts.

GMOs

Genetically engineered organisms aim to modify natural processes without directly changing genes.
Recombinant DNA technology allows for the transfer of specific traits between organisms creating GMOs.
GMOs often offer benefits like enhanced yields, nutritional value, and resilience to environmental stresses.

Potential for genetic contamination and interbreeding between native and introduced species.
Competition with existing species, potentially leading to invasiveness and disruptions in native populations.
Ecological Impacts; possibility of single species changes affecting the greater ecosystem.
Antibiotic resistance concerns linked to the use of antibiotic resistance genes in some GMOs.
