A racoon jumps over a fence in almost deserted Central Park in Manhattan on April 16, 2020 in New York City. Gone are the softball games, horse-drawn carriages and hordes of tourists. In their place, pronounced birdsong, solitary walks and renewed appreciation for Central Park's beauty during New York's coronavirus lockdown. The 843-acre (341-hectare) park – arguably the world's most famous urban green space – normally bustles with human activity as winter turns to spring, but this year due to Covid-19 it's the wildlife that is coming out to play.

Picture dated October 23rd, 2018 shows brother and sister Henry (7) and Lily Sales (9) getting in some early practice for the World Puddle Jumping Championships at Wicksteed Park in Kettering, Northants, UK. Organisers have made more puddles than ever before in an attempt to make this year's competition the biggest and best yet. They are also hoping competitors will set a new record for the most people jumping in puddles at the same time. Judges will give scores based on the height of the jump, enthusiasm, distance of splash and stickability (the amount of mud which clings to each competitor). (Photo by Geoff Robinson Photography)

In this Friday, December 4, 2018 photo, a half sunken cruise ship lays on its side, in the Gulf of Elefsina, west of Athens. Dozens of abandoned cargo and passenger ships lie semi-submerged or completely sunken around the Gulf of Elefsina, near Greece’s major port of Piraeus. Now authorities are beginning to remove the dilapidated ships. Some of them have been there for decades, leaking hazards like oil into the environment and creating a danger to modern shipping. One expert calls the abandoned ships “an environmental bomb”. (Photo by Thanassis Stavrakis/AP Photo)
