    Human and environment interactions Human and environment interactions Presentation Transcript

    • Human and Environment Interactions
    • The Green Revolution • In the 1960s, farmers began using better fertilizers and pesticides (bug sprays) to increase food production.
    • Pros and Cons • Pros • More Crops and Less Famines • Higher Populations • Cons • Dangerous Chemicals got into the environment • Erosion as more land was used for farming
    • Results of Increased Population • Increased populations led to an increase in urbanization (cities) and industrialization • By 2005, 3.5 billion people lived in cities. • 7 billion people live in the world today!
    • Results of Urbanization • Urbanization leads to localized pollution, diseases spread, and increased temperatures (in cities – all the concrete!) • And as previously mentioned, hazardous chemicals get into the environment (last week’s local issue!)
    • Effects on Wildlife • These developments endanger wildlife because people tear down natural habitats to make homes and businesses.
    • Natural Resources • As we utilize the natural resources in increasing industrialized regions, we pollute the world, poisoning more environments and killing more animals.
