On Tuesday, fishermen on Japan’s Pacific coast kill more than 200 dolphins as their annual hunt begins. The dolphins are driven into shallow water in Taiji cove by fishermen using nets and boat engines, where fishermen in boats and some in wetsuits tie their tails to stop them escaping. A tarpaulin is then erected to stop cameras from filming the killing and the blood seeping into the sea.

Study findings show that the widespread use of the pyrethroid pesticide is causing worker bees to hatch at a smaller size and demonstrate ongoing retarded growth. The research, published today in the Journal of Applied Ecology, reveals that prolonged exposure to a pyrethroid pesticide, which is used on flowering crops to prevent insect damage, reduces the size of individual bees produced by a colony.
