O'Brien Lock and Dam, approximately nine miles away from Lake Michigan. The U.S. Army Corps of Engineers has released a final $778 million plan to keep Asian carp from reaching the Great Lakes by strengthening defenses at a lock-and-dam complex in Illinois. The price tag is much higher than the estimated cost of a tentative version of the strategy released in 2017. (Illinois Department of Natural Resources via AP, File)

"If people could just take a few minutes to look at nature closely, I think they would be blown away," Hewitt said. Hundreds of New Yorkers are working with researchers to find and catalog wild plants in their city. They’re taking pictures with their smartphones as they walk the streets. Participants have already found invasive species, plants never documented before in New York City, and endangered native weeds. (AP Photo/Emiliano Rodriguez Mega)
