Human Impact on Earth's Systems


Unit: Human Impact on Earth's Systems
Concepts:
    Anthropogenic Changes
            All over the Earth, human (“anthropo”) activity contributes to climate change. In this concept, you will learn how emissions from the cars we drive, the furnaces or fires that heat our homes, and even the gas passed by the cattle we raise all contribute to the mix.
        Renewable and Nonrenewable Resources
            Water is a renewable resource; coal is a non-renewable resource. This concept will introduce you to the different types of renewable and non-renewable resources.
        Natural Resources
        Human Population Growth
            Any environment can support only a limited number of organisms. This concept will show you how overpopulation can have adverse effects on the environment.
        Over-Exploitation of Resources
            Water is a renewable natural resource, but it is not an unlimited natural resource. Less than one percent of the water on Earth can be used by humans, and that number is growing smaller every day. In this concept, you will learn how to use water and other natural resources wisely.
        Pollution
            It comes from many sources, and it’s usually trash or harmful chemicals, but sometimes too much of a good thing can pollute. In this concept, you will learn about the sources of pollution as well as the harmful effects that pollution can have on the environment.
