Module 1: Embracing Environmental Science

What is Environmental Science?

  • It is a science revealing the relationship between human activities and the environment.
  • It explores the effects of environmental changes on human survival and the laws of environmental evolution.
  • It researches the technical and management measures to comprehensively prevent and control regional environmental pollution.

What are the Three Environmental Processes?

  • Physical Processes
      * Processes shaping and influencing Earth’s physical features, creating constant change
      * Examples: Tectonic Plate Movement, Wind and Water Erosion
  • Biological Processes
      * Processes sustaining balance in ecosystems and are vital for organisms to function
      * Examples: Photosynthesis and Hybridization of Plants, Stimuli Response, Transpiration, Reproduction
  • Chemical Processes
      * Processes producing or converting new chemical substances essential to humans and the environment
      * Examples: Digestion, Combustion, Osmosis, Phase Changes, Plastic Decomposition, Oil Spills, Acid Rain, Global Warming

What Topics Make Environmental Science Interdisciplinary?

  • Species Restoration
      * What should be the reason behind efforts for the restoration of a species’ population?
      * What would be our benefits if certain species will be saved from extinction?
  • Resource Management
      * The sustainable utilization of major natural resources (land, water, air, minerals, forests, fisheries, and wild flora and fauna).
      * Resources → Ecosystem Services
        * Provisioning Services
          * Direct Products of an Ecosystem
          * Examples: Food, Water, Oxygen
        * Regulating Services
          * Processes Regulating Natural Systems
          * Examples: Aquifers and Wells, Pollination, Photosynthesis
        * Cultural Services
          * Non-Material Benefits Contributing to the Development and Cultural Advancement of Peoples
          * Example: Aesthetic Inspiration, Cultural Identity, Recreation, Spiritual Experience
        * Supporting Services
          * Life-supporting Processes
          * Example: Photosynthesis, Water Cycle
  • Environmental Laws
      * How many environmental laws are there in the Philippines?
      * Are environmental laws properly enforced? Do they have any flawed provisions?
  • Sustainability
      * Environment
      * Economy
      * (Social) Equity

What are the Important Steps of the Scientific Method?

  • Observation
      * Asking Question(s)
      * Can be observed by any of the five senses (sight, sound, smell, touch, taste)
  • Research (using reliable sources in learning background information)
  • Hypothesis
      * Predicting what will occur in an experiment
      * “If…then…”
  • Experiment and Data Collection
      * Types of Data
        * Qualitative Data (Descriptions)
        * Quantitative Data (Numbers)
      * Types of Variables
        * Independent Variable (changeable)
        * Dependent Variable (measurable)
      * Types of Experiment Groups
        * Experimental Group (one independent variable altered)
        * Control Group (all other groups are compared to this)
  • Data Analysis
  • Draw Conclusions
  • Share Results

What are the Characteristics of Pseudoscience?

  • What is Psychobabble?
      * These are words sounding scientific but are used incorrectly or misleadingly
      * Example: “biofeedback, meridian lines, quantum energies” justifying “Energy Therapies”
  • What is Anecdotal Evidence?
      * Unverifiable evidence based on personal experiences and events
      * Pseudoscience heavily relies on anecdotal evidence
      * Example: Product Reviews
  • Pseudoscience often uses extraordinary claims without extraordinary evidence supporting the claims
      * Example: Product X eliminates all pain without any scientific basis
  • Pseudoscientific claims are often unfalsifiable, being incapable of being refuted in principle
      * Example: Traditional Chinese Medicine and Qi are concepts incapable of being scientifically measured or tested
  • Pseudoscience is often absent of important scientific research principles:
      * Connectivity to Other Research
        * Connectivity → the extent to which assertions build on existing knowledge
        * Example: “Dilution strengthens potency, water has memory”
      * Adequate Peer Review
      * Self-Correction
        * Example: Astrology
