A list of environmental issues is shown below.
• Rabbits transported from Europe overrun and
deplete farmlands in Australia.
• Many areas in the southeastern United States
are overgrown with the kudzu plant from Asia.
• In parts of New York State, bluebirds must
compete with starlings originally brought here
from England.
All of these issues are the result of
(1) introduction of nonnative species into stable
ecosystems
(2) genetic engineering without using adequate
safety precautions
(3) preservation of habitats due to human
population growth
(4) use of foreign species to replace native
predators
