Frogs are treated with anti-fungal medicine and anything else that has contact with water during amphibian rescue is treated with a bleach solution, from boots and clothing to instruments and transport containers, to be sure researchers are not spreading the fungus to new, uncontaminated areas. When zoos and aquariums bring frogs into protective custody, the enclosures also must be treated with a bleach solution daily for the first few weeks to be sure they help control the spread of fungus.

Environmental Worldviews  Planetary Management  Human beings can and should manage the planet for their own benefit. We are in charge of nature and there are always more resources  Planetary Management  Human beings can and should manage the planet for their own benefit.
