You had better think twice before littering at this Thai national park, as you might find your trash following you home!

Even though it's 2021, we still see people who don't seem to understand the consequences of littering. For example, chemicals and toxic materials in the trash may be blown into rivers, forests and oceans.

Additionally, littering affects air quality, which can help in the spread of diseases.

Luckily, organizations and authorities worldwide are finding new ways to encourage people not to litter (littering penalties, anti-littering campaigns, etc.).

Khao Yai National Park near Bangkok has its unique solution for careless people. Tit for tat, the authorities of the park will send trash back to its owners.

Not only that, but they will also register offenders with the police.

Before entering the park, visitors have to leave their addresses to make it's easier for the park to track them down if they left rubbish behind.

On his Facebook account, Environment Minister Varawut Silpa-Archa posted images of collected, ready-to-be-shipped litter.

"The garbage that tourists left in the park is now packed into boxes. It's ready to be returned to the owners of the garbage,"

"Your trash - we'll send it back to you," he warns, reminding visitors that littering in a national park is unacceptable and punishable with hefty fines and up to five years in prison.

To remind people where their trash came from, they accompany the trash with a note, which says:

"You have forgotten some of your belongings at the Khao Yai National Park. Please let us return these to you."

Park authorities say that the trash people leave behind can pose a threat to animals that try to eat it.

Khao Yai National Park stretches across more than 770 sq miles and is a hotspot for hikers.

Known for its wildlife and natural scenery, it is, in fact, the oldest national park in the country.
