The London Zoo is one of the city’s most-visited places. During normal times, it is filled with visitors, both young and old. However, as the coronavirus crisis continues, the zoo is once again in lockdown, meaning no visitors at all. No one to watch silly monkeys play in trees, dangerous King Cobras sun on rocks, or friendly penguins slide down slippery surfaces. Besides that, the lockdown is causing great economic harm. Every month without visitors costs the zoo about $1.4 million dollars, Reuters news agency reports. So, the future of the world’s oldest scientific zoo is unclear. “We are losing so much money,” zoo employee Kate Sanders told Reuters, “I’m concerned the zoo might not survive.” Sanders is the team leader for big cats at the zoo. She added that having no visitors “has been a really sad time for the zoo.”
