Only about 411 North Atlantic right whales exist, so every animal lost is a blow to the species’ chance of surviving.

The Interior Department is expanding oil and gas leasing on land in six western states that is vital habitat for the greater sage grouse. Lawsuits are certain to follow.
The Endangered Species Act was enacted in 1973 partly to help save the bald eagle, the U.S. national symbol, from extinction. Should public appeal influence which species get priority?
How should the US spend limited funds for conserving endangered species? A new data tool lets managers compare different strategies so they can allocate money to protect the most species.
Green sea turtle.
Little chunks of plastic are now scattered throughout the oceans and pollute most beaches around the world, including the nesting sites of threatened and endangered sea turtles.

The Trump administration is reopening a plan negotiated under President Obama to protect Western sage grouse. This could signal to states not to bother working together to protect other endangered species.
Wild bumble bees provide natural pollination for blueberries in North America.
Honeybees receive a lot of attention, but the first North American bee to be listed as an endangered species is a wild bumble bee. Wild bees are vital pollinators, and some are declining rapidly.

Congress is moving to cut back the Endangered Species Act and give more power to states. But a recent study shows that state laws are weaker and states have few resources to protect species at risk.
