Australia is now overrun with damaging African gamba grass that exacerbate wildfires. Almost impossible to eradicate without copious amounts of equally damaging chemical pesticides, these invasive plants may require fresh thinking, says Professor David Bowman, a professor of environmental change biology at the University of Tasmania. His solution: Bring in African elephants, zebra, or rhinoceros to control these species. This approach could also help ensure there are multiple populations of increasingly rare elephants and rhinos, which are still hunted across Africa. The Australian outback could become a kind of ark.
