Unit Essential Question: How do organisms interact with their environment?
Key Learning: The natural world is full of complex interrelationships.
This complex system can create environmental problems, both natural and
manmade. Scientists have evaluated these risks and have examined alternative
solutions for resolving and preventing them. Today our
global environment is being stressed by many different factors, including
habitat destruction, pollution, invasion of non-native species, global warming,
and depletion of the ozone layer. Life on earth is dependent on the well
being of the environment.
