Thailand is one of the most visited countries in the world. Last year, more than 20 million people visited Thailand's national parks. With an area of 2,000 square kilometers, Khao Yai National Park has a history of 59 years. Every year, it welcomes a lot of visitors. Over the past few years, visitors have left behind nearly 50,000 kg of rubbish. Now the park has a plan to solve the problem.
If visitors don 't take their rubbish away, the park will send a souvenir (纪念品) to them. What is it? It's not the type of souvenir you want as a gift. It's a package(包裹) full of rubbish they have left in the park. Something is on the package: "You forgot something in Khao Yai National Park, so we return it to you."Varawut Silpa-archa, Thailand's Minister of Natural Resources and Environment wrote on the Internet, "I will pick up every single piece of your rubbish, pack them well in a box, and send it to your home."
In order to make it easier for the park officers to return the rubbish, visitors coming to Khao Yai National Park must write down their address.
So think twice next time you want to throw rubbish away.
