    Environmental Science Lecture Series Summary

    • Solar energy powers life on earth, with plants converting sunlight energy into chemical energy stored in sugars, which is then consumed by animals, leading to the flow of energy through the food chain.
    • The environment is defined as the complex of physical, chemical, and biotic factors that act upon an organism or an ecological community. Sustainability is the capability of being maintained at a steady level without exhausting natural resources or causing severe ecological damage.
    • Nonrenewable resources, such as coal, petroleum, natural gas, and nuclear energy, are highlighted for their limited availability, while renewable resources, including solar, geothermal, wind, biomass, and water energy, are emphasized for their replenishable nature.
    • Organic compounds contain carbon and hydrogen, often associated with living organisms, while inorganic compounds lack carbon-hydrogen bonds.
    • Ecology is the study of how living things interact with each other and with their environment, including abiotic and biotic factors.
    • The biosphere includes the combined portions of the planet in which all life exists, including land, water, and atmosphere.
    • Energy is the constant supply that living organisms need, with almost all of Earth's energy coming from the Sun.
    • Biodiversity encompasses the variety of life on Earth and the essential interdependence of all living things, including the diversity of genes, number of species, and ecosystems.
    • The burning of fossil fuels produces excessive greenhouse gases, such as CO2, which contributes to global warming, impacting biodiversity and agriculture.
    • Climate change in the current era is expected to be extremely rapid compared to transitions in and out of past ice ages, making ecosystems more vulnerable to changes.
    • Human activities have many effects on ecosystems, which compound the effects of climate change, making it more difficult for ecosystems to adapt.
    • The earth's carrying capacity for humans is unknown, and the world's population is projected to reach 7.5-10.8 billion by 2050, with population growth in developing countries increasing nine times faster than in developed countries.
