EVERY YEAR, PEOPLE ARE DOING MORE AND MORE TO
SAVE ANIMALS FACING DESTRUCTION OR EXTINCTION
FROM A WIDE RANGE OF DANGERS.
Protecting the Earth’s Animals attacks some of the most
important issues in wildlife conservation around the world,
whether saving rhinos in Africa, trying to free captive killer
whales, or, trying to make sure our pet dogs and cats are well cared for. Endangered
species are just part of the story; entire animal groups are in trouble, to say nothing
of habitats and ecosystems. The human warriors in the battles to help wildlife are the
heroes of the stories in Protecting the Earth’s Animals.
