INTRODUCTION TO ENVIRONMENTAL SCIENCE

INTRODUCTION OF ENVIRONMENTAL SCIENCE

NATURE OF ENVIRONMENTAL SCIENCE

• Environmental Science: An interdisciplinary field that incorporates both scientific and social perspectives on human impact.

  • Interaction Study: Investigates the interplay between Earth’s systems and human systems.

  • Surrounding Conditions: Considers factors affecting organisms.

  • Problem Solving: Utilizes processes for understanding nature through hypothesis testing.

ENVIRONMENTAL SCIENCE

• Complex Domain: Integrates traditional sciences with individual values, societal norms, economic factors, and political awareness to address environmental issues.

• Understanding Requirement: Requires knowledge of scientific principles, economic influences, and political dynamics.

• Multi-faceted Decisions: Scientific or economic decisions may not align with political viability without adaptation.

EARTH AND HUMAN INTERACTION

• Focus: Examines the interaction between the Earth’s environmental systems and human systems.

INTERRELATEDNESS

• Core Concept: Interrelatedness among diverse components is crucial, presenting both interest and challenges in environmental studies.

ECOSYSTEM APPROACH

• Significance: A fundamental method for addressing environmental challenges.

• Ecosystem Definition: A region where organisms and the physical environment form an interconnected unit.

WHAT IS A SYSTEM?

• System Definition: A group of interacting, interrelated parts creating a complex, unified whole.

EARTH AS A SYSTEM

• Component Interaction: Earth consists of interrelated components that shape current and future environments.

• Integrated System: Encompasses interconnected sub-systems, divided into four main components.

COMPONENTS OF EARTH'S ENVIRONMENTAL SYSTEM

• Interactions: Components interact to shape the environment.

IMPORTANCE OF STUDYING ENVIRONMENTAL SCIENCE

• Population Awareness: Understanding the implications of a global population of around 7 billion on Earth.

• Cumulative Effects: Recognizing the impact of human activities on the environment.

GLOBAL ENVIRONMENTAL CHALLENGES

• Significant Issues:

  • Global Warming

  • Overpopulation

  • Waste Pollution

  • Deforestation

  • Climate Change

  • Fossil Fuels

STUDY REASONING

• Understanding Nature: Comprehends natural mechanisms.

• Component Interaction: Recognizes various environmental interactions.

• Human Impact: Identifies how humans influence the environment.

ENVIRONMENTAL ETHICS

ETHICS DEFINITION

• Philosophical Branch: Defines right and wrong actions.

• Complexity: Ethical issues surrounding the environment often conflict human and ecological interests.

GOAL OF ENVIRONMENTAL ETHICS

• Responsibility Framework: Focuses on the moral foundation of environmental responsibility, emphasizing the need for environmental consciousness among individuals.

PHILOSOPHICAL APPROACHES TO ENVIRONMENTAL ETHICS

THREE THEORIES OF MORAL RESPONSIBILITY

• Anthropocentrism

• Biocentrism

• Ecocentrism

ANTHROPOCENTRISM

• Human-Centered: Environmental ethics based on human interests.

• Moral Significance: Only humans are deemed morally significant, with environmental value based on human utility.

BIOCENTRISM

• Life-Centered: All forms of life hold an inherent right to exist.

• Species Responsibility: Increased responsibility to protect animal species over plant species.

ECOCENTRISM

• Ecosystem-Centric: Considers the environment's intrinsic moral worth beyond human or animal interests.

ALDO LEOPOLD

• Influential Ecologist: Advocated for ecocentrism and a community perspective that includes land.

• Philosophy: Stressed the importance of preserving the integrity, stability, and beauty of biotic communities.

ENVIRONMENTAL ATTITUDE

• Complexity: Ethical commitment varies, making it easier to discuss general attitudes.

THREE ENVIRONMENTAL ATTITUDES

1. DEVELOPMENT

   • Anthropocentric; prioritizes human mastery over nature for self-benefit.

2. PRESERVATION

   • Eco-centric; advocates for protecting nature's intrinsic value.

3. CONSERVATION

   • A balanced approach promoting human well-being while considering ecological sustainability.

SUSTAINABLE DEVELOPMENT

• Focuses on appropriate development to alleviate poverty while maintaining ecological health, ensuring future generational resource availability.

SEVEN ENVIRONMENTAL PRINCIPLES

1. Nature Knows Best: Understanding and adhering to natural processes is vital.

2. All Forms of Life are Important: Each organism has a specific role.

3. Everything is Connected: Ecosystem components are interdependent.

4. Everything Changes: Acknowledges environmental dynamics.

5. Everything Must Go Somewhere: Waste has to be managed sustainably.

6. Ours is a Finite Earth: Resources are limited and must be used wisely.

7. Nature is Beautiful: Recognizes humanity's responsibility as stewards of the environment.
