Resources, Trade, and the
Enviroment
ResourcesAs people use more
non-renewable resources (minerals and fossil fuels), scientists work on alternatives.
Renewable resources like Hydroelectric (water), solar (sun), wind, and nuclear energy are some options.
Economic DevelopmentNatural resources
are not evenly distributed on Earth.
In developed countries, a small portion of people work in agriculture.
In developing countries, most people are farmers.
IndustrializationIndustrialization has
recently helped change the economics in countries that once relied on agriculture.

Malaysia
TerrorismCertain militant
groups in developing countries have used terrorism to counter the global influence of developed countries.

the unequal distribution of natural resources.
Countries often add tariffs to imported goods or set limits on how much can be imported.

The North American Free Trade Agreement (NAFTA) has removed trade barriers between US, Mexico, and Canada.
