Defenders' Experts
Threats to Wildlife
From global warming to habitat destruction, disease and invasive species, our nation’s wildlife is under threat. Defenders is on the forefront of these issues, providing expertise to lawmakers and wildlife managers on ways to ensure our nation’s wildlife survive and thrive.
Global Warming
Global warming is one of the gravest threats facing wildlife today,
and plants and animals around the country are in real danger of falling
victim because their habitat is changing too rapidly for them to keep up.

Habitat Loss
Habitat loss is the leading threat to biodiversity in the U.S. It is more prevalent
and affects more species than disease, pesticides, invasives or
global warming.
Disease
Many disease threats to birds, mammals,
amphibians and fish originated in other parts of the world. These pose a
particular threat because most native species lack an immune response.
Invasive Species
Invasive species are plants, animals, and microbes that are out of
place and out of control. Nearly half of the species currently listed
under the Endangered Species Act are threatened by invasive species.

Overexploitation
Overexploitation of natural resources, through unsustainable
hunting, fishing, or extraction of raw material, can result in the
extinction of species and the loss of genetic diversity within others.
