No Pennsylvania agency currently protects endangered insects and other terrestrial invertebrates. New legislation would fix the regulatory gap

There aren’t as many American bumble bees (Bombus pensylvanicus) as there used to be in the state the insect is named after.

Philadelphia is facing a silent crisis: the rapid loss of its urban tree canopy. Over the past decade, we’ve lost at least 7% of our trees—shade-giving, air-cleaning, life-enhancing sentinels that shape the character of our city. The benefits of trees are indisputable.

When the Fairmount Water Works was built in the early 19th century to provide clean drinking water to Philadelphia, it was a feat of modern engineering. Steam engines and a dam across the Schuylkill River powered water wheels large enough to pump millions of gallons a day uphill to a reservoir atop nearby Fair Mount.
