What is the "Tragedy of the Commons" and what observations did Garrett Hardin
make in developing his ideas?
Garret Hardins well-known article, called The Tragedy of the Commons, refers to
the decline of the commons, which Harden defines as any form of pr
The American whooping crane and the California condor are two of North America's largest
birds. Although both are rare and endangered, they are protected, and large preserves are
available for them. The two species, however, seem to be responding differe

PROPERTIES OF ACIDS
Acids have several distinctive properties.
Acidic compounds have a tart or sour taste. Ex:
vinegar, lemons, and limes
Aqueous solutions of acids are electrolytes
(conduct electric current).
Acids cause ce
