The story of this incredible species isn’t over yet.

A big win for black rhinos. 🦏 👏

The recently established Tsavo West Rhino Sanctuary now provides 3,200km² of rhino habitat, hugely expanding the existing 92km² Ngulia Rhino Sanctuary.

This positive step will help encourage population growth with hopes to increase no’s in Kenya to 2,000 by 2037. 💚

U.S. Biofuels Target Could Fuel Destruction of Tropical Rainforests This article was originally published by Inside Climate News and is reproduced here as part of the Climate Desk collaboration.

The U.S. doesn’t produce enough vegetable oil to meet a new biofuels mandate, so suppliers will have to ramp up imports of vegetable oil, putting pressure on tropical forests overseas. via @insideclimatenews.org

How California’s war on smog and its ambitious car pollution rules made everyone’s air cleaner The Clean Air Act gave California the authority to issue tough pollution standards for vehicles, with EPA approval. The Trump administration is now trying to stop it.

“Catalytic converters have removed 8 billion tons of pollution from the air in the U.S. They have saved hundreds of thousands of lives and led to the removal of a deadly neurotoxin, lead, from the atmosphere.”
