The COVID-19 pandemic has led to emptier coastal areas around the world.Animals like sea turtles have used the chance to reclaim the less-polluted, quieter beaches to lay their eggs during the breeding season.The main breeding season for sea turtles goes from September to November.Workers from the Sindh Wildlife group in Pakistan recently watched as a female turtle walked across the beach in Karachi late one night.She was looking for a place to lay her eggs.She buried a hundred or more eggs in the sand before heading back out into the Arabian Sea.Sindh Wildlife counted 15,000 green turtles on Karachi's beaches last year.By comparison, the group counted between 8,000 and 8,500 in 2019.Pandemic-related lockdowns there had ended by the start of this year's breeding season.But animal experts still expect a large number of the endangered animals to visit.Green turtles are among the world's largest sea turtles.Adults can weigh more than 90 kilograms.
