Species at Risk Act
Species at Risk Act Environment Minister David Anderson will
re-introduce his Species at Risk Act to the House of Commons on
Friday. The Act will protect many rare and endangered plants and
animals. It will also require the government to develop a plan to
help the species recover. This will be the fourth attempt by the
government to pass a law to protect endangered species. A survey
earlier this month showed that more that 90% of Canadians would be
in favour of this law. FEBRUARY 1, 2001
