THIS WEEK, between January 18th and 27th, thousands of volunteers in a band of territory stretching across north-eastern Australia from Darwin to Brisbane are venturing into the night with torches and collecting-buckets. They are taking part in the Great Cane Toad Bust, an annual attempt to keep a lid on the population of these invasive, toxic amphibians. Toads thus caught will be killed humanely by being chilled in refrigerators and then frozen.
