Study Notes
Human Impact on Earth's Ecosystems
- Climate change, decreasing water resources and biodiversity loss are urgent issues requiring action to manage human impacts on Earth's ecosystems.
- The text emphasizes the importance of understanding how we use Earth's resources and sustain or exhaust them with growing populations and climate change.
The Hierarchy of Biological Organization
- Biological organization is a hierarchy of complex biological structures and systems.
Ecology
- Ecology studies interactions and relationships between living organisms, including humans, and their physical environment.
- It explores the impact of both abiotic (non-living) and biotic (living) elements on an organism's surroundings.
- The term "ecology" was coined in 1866 by Ernst Haeckel, who conceptualized it as the "economy of nature".
- Natural selection and evolution provide the foundation for ecology.
- Ecological levels of organization include: organismal ecology (individual response to environmental changes), population ecology (groups of the same species), community ecology (all populations in a particular time and space), and ecosystem ecology (communities and their physical environment).
Role of Ecology
- Understanding the environment through research provides information to better understand the world, improve the environment, manage resources, and protect human health.
- Ecology plays a vital role in public health, natural services, and biomedical contributions.
Biodiversity
- Biodiversity encompasses the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems.
- It considers diversity within species, between species, and of ecosystems.
Components of Biodiversity
- Genetic Diversity: refers to the total number of genetic characteristics in a species' genetic makeup
- Species Diversity: refers to the number of species in an area.
- Ecosystems Diversity: encompasses the variety of habitats, communities, and ecological processes.
Importance of Biodiversity
- Provisioning: provides food, medicine, materials for clothing and shelter.
- Regulating: ensures a functional environment through processes like natural resource renewal.
- Culture: promotes health through inspiration, education, recreation, and traditional knowledge.
- Supporting: supports fundamental life processes like the creation of organic matter and nutrient cycling.
Threats to Biodiversity
- The text highlighted the impact of feral cats on wildlife.
Philippine Biodiversity
- The Philippines is known as the "Center of the Center of Marine Biodiversity".
Governance and Biodiversity
- The Philippines is a signatory to the Convention on Biological Diversity (CBD).
- CBD reports provide updates on Philippine biodiversity, management efforts, and future targets.
- The CBD Framework includes the Aichi Targets (2010-2020) and Kunming-Montreal Targets (2020-2030).
Sustainable Development Goals (SDGs)
- The SDGs aim to transform the world by ending poverty and inequality, protecting the planet, and ensuring health, justice, and prosperity for all.
- Highly developed countries (18% of the world's population), including the US, Canada, most of Europe, and Japan, contribute significantly to resource consumption and pollution.
- Moderately developed countries such as Turkey, South Africa, Thailand, and Mexico have fewer opportunities for income, education, and healthcare.
- Less developed countries like Haiti, Bangladesh, Rwanda, and Laos have abundant cheap, unskilled labor but limited capital investment.
Types of Resources
- Nonrenewable resources: are present in limited supplies and are depleted with use.
- Renewable resources: are replaced by natural processes and can be used forever if not overexploited.
Sustainability and the Environment
- Sustainability: is achieved when the environment can function indefinitely without declining from human-imposed pressures.
- Environmental Science: studies the environment, its living and non-living components, and its problems.
- Environmental Science incorporates natural sciences (biology, chemistry, earth science, physics, and medicine), social sciences (economics, political science, sociology, history, philosophy, and ethics), and other sciences (mathematics, statistics, technology, business and management, law, religion, morality, and aesthetics).
Goals of Environmental Science
- To develop a sustainable world.
- To study environmental problems and issues.
Sustainability and Human Values
- Sustainability is a crucial goal that can be achieved with a newfound reverence for life, a commitment to sustainability, active efforts for justice and peace, and joyous celebration of life.
- Pollution and environmental degradation are exacerbated by high resource consumption per person in a population.
