As human beings retreat (退回) into their homes with the covid-19 expanding across the world, nature seems to be taking back urban areas.

According to The Straits Times, many wild animals have recently skipped onto empty streets in many cities. In Spain, a wild boar (野猪) climbed down the hills and wandered around Barcelona. Sika deer nosed their way around the deserted subway stations of Nara in Japan. It is certainly great news for species because this is the habitat they once had and that humans have taken away from them.

Hundreds of years ago, people lived in harmony with wildlife. They shared natural resources from sunlight to water and from forests to land. But as human beings evolved and formed their own civilizations, they fought with animals for more space and resources. Gradually, human beings came to lose connection with nature. More skyscrapers were built to meet the needs of the flock of people in the cities, which drove away many wild animals from their habitats.

However, the recent lockdown of cities during the pandemic gives a chance of freeing space for other animals and reflecting on humans’ relationship with nature. Stuck indoors, with their worlds reduced to a few square meters, urban people have suddenly become keen bird-watchers. They have realized that the sky is a great arena — anything can fly past and, at the very least, it will give them peace. The message is simple: keep looking up.

Right now the most important phenomenon perhaps is humans’ relationship with nature is changing-with people locked up in their homes realizing how much they miss nature. More importantly, by missing nature, humans may come to respect — and live in harmony with-nature once again.
