Sep 11, 2025

Overview

This lecture introduces the seven key environmental principles, providing foundational concepts for understanding human impacts on the environment and strategies for sustainable management.

Introduction to Environmental Principles

  • Environmental principles guide decision-making to minimize negative impacts on nature.
  • They help balance human needs with environmental protection for long-term sustainability.

The Seven Environmental Principles

1. Nature Knows Best

  • Natural processes and ecosystems function optimally without human interference.
  • Human interventions can disrupt these processes, leading to unintended consequences.

2. All Forms of Life are Important

  • Every organism, regardless of size or function, contributes to ecosystem balance.
  • Biodiversity ensures ecosystem resilience and productivity.

3. Everything is Connected to Everything Else

  • Ecosystems are interconnected; a change in one component affects others.
  • Human actions in one area can have far-reaching environmental impacts.

4. Everything Changes

  • Environmental conditions and ecosystems continuously evolve through natural processes.
  • Adaptation is necessary for organisms, including humans, to survive.

5. Everything Must Go Somewhere

  • Matter cannot be destroyed; waste produced by humans stays in the environment.
  • Pollution accumulates, affecting air, water, and soil quality.

6. Ours is a Finite Earth

  • Earth’s resources are limited and can be depleted by overuse.
  • Sustainable use of resources is vital for future generations.

7. Nature is Beautiful and We are Stewards of God’s Creation

  • The environment provides aesthetic, spiritual, and recreational value.
  • Humans have a moral responsibility to care for and protect the environment.

Key Terms & Definitions

  • Ecosystem — a community of living organisms interacting with their physical environment.
  • Biodiversity — the variety of living species in an ecosystem.
  • Sustainability — meeting current needs without compromising future generations’ ability to meet theirs.
  • Pollution — introduction of harmful substances into the environment.

Action Items / Next Steps

  • Review the seven environmental principles and their real-world examples.
  • Prepare to discuss how these principles apply to local and global environmental issues.
  • Complete assigned reading on human-environment interactions.
