Study Notes

Environment

The environment is a complex system composed of living (plants, animals) and non-living entities (air, water, land, energy).
The environment includes socio-economic components like people, communities, institutions, and values.

The Seven Environmental Principles by Barry Commoner

Everything is connected to everything else: Ecosystems are fundamental units of nature, representing the intricate interactions between living (community) and non-living components of the environment.
All forms of life are important: This principle underscores the need for biodiversity, recognizing that each organism plays a crucial role (niche) within an ecosystem.
Everything must go somewhere: This principle highlights the importance of waste management and environmental management systems, as there is no such thing as "away" when it comes to waste.
Ours is a finite earth: Emphasizes the need for conservation and sustainable development. The text describes three approaches: Preservation (no touch), Conservation (wise use), and Sustainable Development (meeting current needs without compromising future generations).
Nature knows best: This principle advocates for ecological technology, suggesting humans first understand and follow natural laws to ensure sustainable use of natural resources.
Nature is beautiful, and we are stewards of God’s creation: This principle emphasizes the inherent beauty and divinity of nature, stressing the importance of stewardship and recognizing the influence of religion on environmental values.
Everything changes: Recognizes three types of changes: linear change (evolution of specie), cyclical change (influenced by time, seasons), and random change (volcanic eruptions, natural disasters).

Philippine Ecosystems

Forest ecosystems are communities of trees, shrubs, herbs, microorganisms, and animals, with trees being the defining structure.
Marginal Lands/Uplands are public lands with steep slopes (greater than 18%) and are generally not suitable for wet rice cultivation without terracing and groundwater management.
Protected Areas are designated zones harboring remarkable features, considered biologically important and home to rare and endangered species.
Freshwater and Wetlands are areas of marsh, fen, peatland, or water, with varying water conditions (fresh, brackish, salt), including marine water up to 6 meters deep.
Lowland/Agricultural Ecosystems are home to 59% of the Philippine population and house 70% of its municipalities.
Coastal and Marine Ecosystems are significant because they support 70% of the country's municipalities and most major cities.
Urban Ecosystems represent the built environment with significant human influence.

Biological Diversity (Biodiversity)

Biodiversity refers to the variety of all life forms on Earth, encompassing plants, animals, and microorganisms.
The text highlights three kinds of biodiversity:
- Ecosystem Diversity - Interdependence within ecological communities.
- Species Diversity - The fundamental unit of biological classification.
- Genetic Diversity - Variations within species.

Natural Resource Management

Natural resources can be classified as renewable (forest) or non-renewable (minerals).
The text outlines a natural resource management approach that includes:
- Reforestation and community-based management
- Soil and water conservation techniques (agroforestry)
- Biodiversity Conservation through Protected Area establishment and regulation of wildlife trade
- Ex-situ conservation techniques
- Integrated coastal resources management
- Environment-friendly aquaculture
- Solid Waste Management
- Community Organizing/involvement
