An illegally imported chow chow puppy in a kennel at a Dogs Trust rehoming facility on May 6, 2021 in an unspecified location in the United Kingdom. Dogs Trust have seen a marked increase by 66% of illegally imported puppies during the coronavirus pandemic as demands and street values have risen dramatically. Many of the dogs are imported from Eastern European countries, taken from their parents too young and enduring long and cruel journeys entering the U.K. under the current legal age of 15 weeks. Dogs Trust are calling on the U.K. government to raise the age of imported puppies to 6 months to make them less desirable and to also see tougher penalties for smugglers as currently only a handful of cases have lead to prosecution with minor penalties.

This picture taken on April 20, 2021 shows an aerial view of sharks swimming near an inflatable kayak in the shallow Mediterranean Sea water off the Israeli coastal town of Hadera north of Tel Aviv. Dozens of sandbar (Carcharhinus plumbeus) and dusky sharks (Carcharhinus obscurus), which can grow up to three meters in length, have gathered off the coast of northern Israel, where the waters of the Mediterranean are warmer due to the impact of the Orot Rabin power plant, prompting the authorities to warn residents to stay away. The sharks, which are known to frequent the waters, can grow up to three metres (10 feet) in length. Of the two species, sandbar sharks are not considered dangerous to humans.
