    Study Notes

    Ecological Resistance and Resilience

    • Ecosystems can maintain their structure and function in the face of disturbances like hurricanes and wildfires. This is called ecological resistance.

    • Ozone depletion can have serious consequences, including increased skin cancer rates and hindered plant growth.

    • NASA studies confirmed the existence of a growing ozone hole over Antarctica.

    Influencing Decisions

    • Institutions utilize incentives and communication strategies to encourage individuals to reduce their environmental impacts.

    Individual and Collective Environmental Impacts

    • The US has a land area of 983 million hectares, but its ecological footprint exceeds 2.6 billion hectares. This indicates unsustainable resource consumption.

    Historical Sustainability Practices

    • Indigenous peoples, such as those in the Pacific Northwest, practiced sustainable resource use for generations.
