Biodiversity and Healthy Society

Study Notes

Biodiversity is the diversity of living organisms across terrestrial, marine, and aquatic ecosystems, including diversity within species, between species, and of ecosystems.
It provides essential ecosystem services that contribute to human well-being, including food security and healthcare.
Understanding and protecting biodiversity is critical for a healthy society.
Major objectives include understanding the interrelationship between society, environment, and health, and identifying threats to biodiversity like human-caused species loss.

Biodiversity hotspots are regions with a high number of unique species that are threatened by habitat loss.
Most hotspots are located in tropical regions, particularly rainforests and areas with high endemism.

Biodiversity supports civilization growth and development by providing critical resources.
Modern consumerism threatens biodiversity as it prioritizes short-term gains over sustainable practices.
Sustainable use of biodiversity allows for the development of new products for future generations.

Genetic Diversity: Refers to variations within a species. High genetic variability ensures a healthy breeding population, reducing the risk of in-breeding and extinction.
Species Diversity: Represents the variety of species in an ecosystem. Tropical rainforests showcase high species diversity, while deserts have lower diversity. Approximately 1.8 million species have been identified, but this could be only a fraction of existing species.
Ecosystem Diversity: Comprises various ecosystems, including forests, grasslands, deserts, and mountains, each with distinct characteristics and biodiversity levels.

Human decisions significantly impact biodiversity, positively and negatively.
The loss of biodiversity due to habitat destruction and other activities threatens ecosystem services crucial for human survival.
Conservation efforts are essential, as biodiversity supports agricultural productivity, disease resistance, and the development of innovative biotechnological solutions.

Viewing and discussing endangered species helps raise awareness of threats and the importance of protection.
Creative activities, such as creating artwork reflecting biodiversity threats, can foster a deeper understanding of environmental issues.
