2. Dodos - thes e proverbial birds went extinct in the mid-to-late 17th century and their disappearance is directly attributable to human activity.

3. Polar bears - Polar Bears have become endangered in large part because of global warming and climate change in the Arctic.

4. Muskox - they nearly became instinct because of over-hunting throughout the late 1900s until the 1930s.
