New challenges to human adaptation and social change

• “It’s not the strongest of the species that survive, nor the most intelligent but the ones most responsive to change”

  -Charles Darwin
• Adaptation

  • refers to a change or the process of change by which an organism or species become better suited to its environment.
• Adaptation

  • enhance the fitness and survival of individuals.
• Adaptation Traits

  1. Structural Adaptation
  2. Behavioral Adaptation
  3. Physiological Adaptation
• Structural Adaptation

  • are physical features of an organism such as shape, body covering, armament; and even the internal organization.
• Structural Adaptation

  Examples:

  ✓ Giraffe's long neck - help them reach food high up in tress that other animals cannot.

  ❖ Physical-looks
• Behavioral Adaptation

  • are composed of inherited behavior chains and/or the ability to learn.
• Behavioral Adaptation

  Examples:

  ✓ Bears hibernate in winter to escape the cold temperature and preserve energy.

  ✓ Birds migrate

  ❖ Behavioral-Act
• Physiological Adaptation

  • an internal body process to regulate and maintain homeostasis for an organism to survive in the environment in which it exist or permit the organism to perform special functions.
• Physiological Adaptation

  Examples:

  ✓ Snakes and spiders produce venom to paralyze their prey and make them easier to digest.

  ✓ The existence of morning sickness in pregnant women.
• Human Adaptation

  • ability of humans to be able to rapidly adapt to varying environment conditions and changes has made it possible for them to survive in any regions or places anywhere in the world.
• Humans can normally adapt to environment changes in several ways such as:

  1. Genetic Change
  2. Developmental adjustments
  3. Acclimatization and cultural practices
  4. Use of technology
• Global warming

  • results when carbon dioxide (CO2) and other air pollutants and greenhouse gases build up in the atmosphere, they absorb sunlight and solar energy that has bounced off the earth's surface.
• Global warming

  • refers to a gradual rise in the average temperature of the Earth's atmosphere and oceans, a phenomenon that is thought to be irreversibly altering the Earth's climate.
• Effects of Global warming

  1. Temperature rises on average
  2. Seasonal changes
  3. Severity of harsh weather events
  4. Water and food shortages
  5. Increased health risks
  6. Coastal inundation
  7. Increased frequency and intensity of cyclones and hurricanes are all factors to consider.
• Climate change

  • has arisen as a result of global warming. These terms are sometimes used interchangeably, but they are distinct.
• Climate change

  • changes in weather patterns and growing seasons all around the world.
• Climate change

  • is a result of global warming, and it poses a severe threat to human life on the planet in the form of widespread flooding and catastrophic weather.
• Typhoon Haiyan

  • also known as Super Typhoon Yolanda in the Philippines, was one of the most intense tropical storms ever recorded and was caused in part by climate change.
• Yolanda

  • was said to have been caused by global warming and climate change. The issue is that most of us are aware that climate change will have a significant impact on our society, but we do not fully comprehend the phenomenon.
• Climate change

  • will have an impact on every area of society, the environment, and the economy. Human behavior, livelihoods, infrastructure, laws and regulations, and institutions are all likely to be impacted.
• Ways to adapt to the situation of Global warming and Climate change

  1. Practice conservation of natural resources
  2. Reduce pollution and waste
  3. Reuse water
  4. Recycle products
  5. Conserve energy
