Human Adaptation on New Challenges

Key Concepts

  • Adaptation: Process by which organisms or species become better suited to their environment.

    • Involves physical changes, behaviors, and physiological adjustments.

Constant Change

  • Quote: "The only constant thing in this world is change."

Learning Objectives

  • Identify new challenges to human adaptation and social change.

  • Explain effects of global warming, climate change, and transmigration of families and values.

  • Examine human responses to contemporary societal challenges.

Types of Adaptations

Structural Adaptations

  • Physical features assisting survival (e.g., penguin blubber).

Behavioral Adaptations

  • Inherited behaviors and learned actions (e.g., bear hibernation).

Physiological Adaptations

  • Functions enabling survival (e.g., venom in snakes).

  • Adaptation involves managing risks and opportunities in changing environments.

Human Adaptation Mechanisms

Genetic Change

  • Inherited modifications improving survival.

    • Example: Immunity to malaria in populations with a history of exposure.

Developmental Adjustments

  • Changes in growth patterns due to environmental stresses; typically irreversible.

Acclimatization and Cultural Practices

  • Reversible responses to environmental stress (e.g., body fat adjustments).

Use of Technology

  • Development of technological aids for environmental adjustments (air conditioners, heaters).

Addressing Global Warming and Climate Change

Mitigation Strategies

  • Programs aim to reduce vulnerability to climate change.

  • Defined as technological changes that lower resource inputs and emissions.

Examples of Mitigation

  • Efficient energy generation technologies.

  • Transition to renewable or low-carbon energy sources.

  • Sustainable resource management practices.

Migration

Types of Migration

  • International Migration: Permanent move across national boundaries.

    • Categories: legal immigrants, illegal immigrants, refugees.

  • Internal Migration: Movement within national borders (states, cities).

  • Circulation Migration: Temporary movements (e.g., for work or study).

Overseas Filipino Workers (OFW)

  • Filipinos working abroad temporarily or permanently.

  • Consequences for migrant families: Long-term parental absence, weakened family relationships, higher incidences of divorce or separation.

Activity

  • Diamond Picture Collage: Draw effects of climate change with descriptions.
