Hikers visiting Mount Halla, the highest mountain in South Korea, often bring the instant noodles with them as a snack. When they’re finished eating, they discard the leftover broth on the ground.

Visitors are dumping between 26 and 31 gallons of broth per day, reports the Korea Times’s Jung Da-hyun.

Authorities are concerned about the environmental implications of this trend, as the salty liquid could run off into streams and harm aquatic wildlife. They’re also worried about how ramen broth will affect the growth of endangered plant species on the mountain. The smell is attracting wildlife like crows and weasels.

To address the issue, the National Park Office of Mount Halla has started an initiative to encourage visitors to keep the mountain clean.
