Bacteria, Plants Turn Garbage Dump into Beautiful Park
Thanks to the help of some hungry bacteria and plants, a 150-foot high garbage dump in Colombia is being transformed into a public park. The microbes and greens are neutralizing the contaminated soil, sucking up heavy metals and feasting on chemicals. Wired’s Olivia Solon describes how the project got off the ground: A team from [...]
