    • Global Warming: Implicates broader health concerns relating to temperature changes.
    • Pollution: Air, soil, etc., with several types, each posing unique public health risks.

    Global Environmental Issues - Overpopulation

    • Overpopulation - the existing human population exceeds the Earth's carrying capacity.
    • Population growth has significantly increased in recent decades.
    • Projected population to reach 10.8 billion by 2100, according to the UN.
    • Increased demand for resources, including food, water, and energy, due to overpopulation.
    • Resource scarcity has led to conflicts and environmental degradation and possibly epidemics.

    Global Environmental Issues - Deforestation

    • Species-rich forests, primarily in the tropics, are frequently destroyed for agricultural activities, including cattle ranching and plantations.
    • Loss of forests results in a loss of biodiversity.
    • Significant forest areas are destroyed annually, mostly in the tropics.
    • Tropical forests are now down to 6-7% of their original coverage.
    • Logging and burning degrade remaining forests.

    Global Environmental Issues - Water Pollution

    • Water pollution occurs when harmful substances, often chemicals or microorganisms, render bodies of water toxic.
    • Sources of water pollution include industrial discharge, agricultural pesticide runoff, inadequate municipal sewage treatment, accidental oil spills, and mine discharge.

    Global Environmental Issues - Waste

    • Solid waste management is a critical concern due to the accumulation and improper disposal of solid waste.
    • Contributing factors to waste generation include rapid population growth, urbanization, industrial activity, consumerism, and insufficient waste infrastructure.

    Global Environmental Issues - Air Pollution and Climate Change

    • Burning fossil fuels, deforestation, and agricultural practices have increased atmospheric CO2 concentrations, from 280 ppm 200 years ago to approximately 400 ppm today.
    • Air pollution, including carbon overload, from burning coal, oil, or wood, is a major health concern.
    • Air pollutants cause health issues including diseases, due to toxins and carcinogens.

    Global Environmental Issues - Climate Change

    • Long-term shifts in temperatures and weather patterns, potentially natural but currently primarily influenced by human activities.
    • Human activities, particularly the burning of fossil fuels, are the primary driver of current climate change.
    • Extreme weather events, rising temperatures, sea-level rise, and changing precipitation patterns are observed effects.
    • Climate change has implications for ecosystems, agriculture, food security, health, and requires international collaboration.

    What are the Solutions?

    • Sustainability and sustainable development are essential for a healthy planet.

    Sustainability

    • The ability of the Earth's natural systems and economies to survive and adapt to changing environmental conditions indefinitely.

    Pillars of Sustainability

    • Environmental: a viable natural environment with biodiversity, materials, energy, and biophysical interactions
    • Economic: maximizing income while maintaining a constant or increasing stock of capital. This includes money and capital, employment, technological growth, investment, and market forces.
    • Social: maintaining stability of social and cultural systems with human diversity, equity, and quality of life. This includes the development of institutional structures and political structures.

    Sustainability Principles - Life on Earth

    • Life has been supported for 3.5 billion years by solar energy, biodiversity, and chemical cycling.
    • Life relies on energy from the sun and natural resources supplied by Earth.

    Sustainability Principles - Dependence on Solar Energy

    • Warms the Earth
    • Provides energy for plants and other organisms with photosynthesis.
    • Powers the hydrologic cycle, including flowing water.
    • Powers wind and can be converted into electricity.

    Sustainability Principles - Biodiversity

    • Provides ecosystem services and adaptability.
    • Many ecosystems are categorized as deserts, forests, oceans, grasslands.
    • Species and systems renew soil and purify air and water.

    Sustainability Principles - Chemical Cycling

    • Natural processes recycle nutrients.
    • Recycling nutrients is vital because they continuously circulate through ecosystems.
    • Nutrients cycle from living organisms to the nonliving environment and vice versa.
    • Chemical cycles are essential for maintaining life.
    • In nature, waste is a useful resource, highlighting interdependence.

    Living More Sustainably

    • Sustainability is central to living more sustainably.
    • Natural capital (natural resources + ecosystem services) is essential. Ecosystem services and resources are driven by solar energy, photosynthesis, and the natural cycles.
    • Human activities are degrading natural resources faster than nature can restore them, creating issues like pollution and overconsumption.

    What is a Resource?

    • A resource is anything we obtain from the environment.
    • Some resources are readily available, but others require technology to acquire.
    • Sustainable resource use includes reducing, reusing, and recycling.

    Natural Capital

    • Natural resources (e.g., air, water, minerals) plus ecosystem services (e.g., air purification, water purification, nutrient cycling).

    Types of Resources

    • Inexhaustible: perpetually available (e.g., sunlight).
    • Renewable: replenished by natural processes (e.g., water, air).
    • Nonrenewable: fixed quantities, renewed through geological processes (e.g., fossil fuels).

    Natural Resources (contin.)

    • Sustainable yield: Using the largest amount of a resource without depleting it or reducing it's capacity to replenish in the future.
    • Environmental degradation: When the rate of use exceeds the natural rate of reproduction/replenishment.

    Natural Services

    • Functions of nature like air and water purification, nutrient cycling.
    • These are vital for a healthy environment.

    Resource Use and Environmental Impact

    • Industrialized countries use a significantly higher percentage of global resources (88%) and produce 75% of global pollution with a population of only 17%
    • Developing countries, conversely, use a smaller amount of global resources compared to industrialized countries.

    Ecological Footprints

    • The amount of biologically productive land and water needed to support a population in a given region, accounting for resources and waste products.
    • A deficit exists when use surpasses the natural rate of replenishment.
    • Upcycling is a sustainable method for minimizing environmental impact by reusing materials.
    • Current human use of Earth's resources is causing degradation of natural capital and creating pollution.

    Recent Global Measures (MDGs)

    • Millennium Development Goals were adopted in 2000 and aimed to reduce poverty including hunger, illiteracy, and disease by 2015.

    Latest Global Measures (SDGs)

    • Sustainable Development Goals were created in 2015 to continue global progress towards addressing many of the same challenges as the MDGs, in an expanded manner with added emphasis on partnerships.

    Sustainable Development

    • Development that meets the present needs without compromising the future generations' ability to meet their own needs.

    Sustainability Principles (SDG's)

    • Planet: Protecting the planet through sustainable resource management, and urgent climate action.
    • People: Ending poverty and hunger, ensuring dignity, and a healthy environment.
