    Study Notes

    Environmental Stress

    • Environmental stress is caused by the negative interactions between a person and their environment.
    • Environmental stressors are demands placed upon us by environmental factors.
    • Pollution is a type of environmental stressor and is an undesirable change in the environment primarily caused by human activities.
    • The different types of pollution include air pollution, water pollution, noise pollution, crowding and the greenhouse effect.

    Human-Environment Relationship

    • Humans and nature have a symbiotic relationship, meaning they depend on each other.
    • Humans exploit natural resources without thinking of the impact on the environment.
    • The quality of air, water, and food is significantly, negatively impacted by unmanaged human activity.

    Air Pollution

    • Air pollution has severe health consequences for humans, including respiratory problems, death and increased risk of cancer.
    • The burning of fossil fuels contributes significantly to air pollution.
    • Pollution from industrialization, vehicle traffic and the disposal of garbage are major contributors to air pollution.

    Water Pollution

    • Contaminated water is a major source of disease, including diarrhea, intestinal worms, and hepatitis.
    • Domestic wastewater, industrial wastewater, and agricultural runoff are significant contributors to water pollution.
    • Water pollution significantly impacts human health, and if left unchecked, will lead to major water shortages.

    Noise Pollution

    • Noise pollution causes irritation, discomfort, and stress and has been linked to various negative health effects.
    • High levels of noise pollution can contribute to anxiety, depression, and aggressive behavior.
    • Noise pollution can also affect communication and performance in various settings, including workplaces and schools.
    • Noise pollution is associated with accidents due to distractions and reduced concentration.

    Crowding

    • Crowding is a form of stress involving subjective discomfort and physiological arousal.
    • Crowding causes a sense of loss of control, decreased privacy, and negative perception of space.
    • Crowding is associated with crime and negative emotions.
    • Overcrowding in prisons contributes to increased risk of violence.
    • Crowding in psychiatric institutions can exacerbate symptoms.
    • Crowding negatively impacts emotion and behavior.

    Methods to Manage Environmental Stress

    • The text provides a few tips to help with environmental stress management, but does not explicitly name them as such.
    • The text stresses the importance of considering the human-environment relationship and managing our impact.
    • The text urges people to "conserve oil," "plant trees," and "save water" to help manage our impact on the environment.
    • The text suggests the importance of awareness about our impact on the environment and the need for sustainable development.

    Environmental Stress

    • Increased Stress: Crowded situations can lead to heightened stress, resulting in faster heart rates and higher blood pressure.
    • Emotional Responses: Crowding primarily triggers anger and aggression as emotional responses, but it can also lead to apathy, social withdrawal, and learned helplessness.
    • Co-existing Factors: The effects of crowding on human behavior and experience are intertwined with other environmental factors.

    Green House Effect

    • Causes: Human activities, like burning fossil fuels, deforestation, and the use of chlorofluorocarbons (CFCs), contribute to global warming.
    • Impacts: Global warming leads to increased storms, melting ice caps, rising sea levels, and changes in climate patterns, which can disrupt agriculture and ecosystems worldwide.
    • Reversing Effects: Mitigation strategies include reducing carbon dioxide emissions, planting more trees, and banning CFC use.

    Sustainable Development

    • Definition: Development that meets present needs without jeopardizing the ability of future generations to meet their own needs.
    • Goals: Preserves natural resources, including both renewable and non-renewable sources.
    • Challenges: The wasteful consumption style and the excessive use of non-renewable resources pose significant challenges to sustainable development.

    The Difference Between Wants and Needs

    • Wants: Desires or wishes that are not essential for survival.
    • Needs: Basic requirements for physical survival, such as air, food, water, and shelter.
    • Sustainability: Buying unnecessary items wastes money and contributes to the depletion of natural resources. Living simply with fewer wants but rich inner life can be more sustainable.
