（单词翻译）

Experts say Pacific island fires are increasing, creating environmental damage that affects important and limited resources for millions of residents.

From Micronesia to Hawaii, wildfires have been a growing problem for many years. With little financing to prevent and deal with these fires, island communities have struggled to control the problem.

Clay Trauernicht of the University of Hawaii said that on tropical islands, fires have strong effects. These fires can, in his words, wreak¹ havoc² – meaning to cause much destruction or confusion - because the native environment evolved without regular fires.

"Fires were very rare prior to human arrival on any Pacific island. ... And so when you do get these fires, they tend to kind of wreak havoc," Trauernicht said.

But it's not just burnt land that is affected³. Island fires harm areas from the top of mountains to below the ocean's surface.

Trauernicht said that soil gets carried away during heavy rainstorms after the fires have removed all the plant life, which has an effect even on ocean life and coral reefs.

Pacific island reefs support local food production, create barriers to large storms, and are an important part of tourism that keeps many islands running.

The wet season on tropical islands also causes some grasses to grow tall and thick, building fuel for the next summer's wildfires.

Michael Walker is Hawaii's state fire protection forester. Walker noted⁴ that Guinea grass, a kind of grass that can grow very fast, creates "really fast-moving, very hot, very dangerous fires."

A recent wildfire on Hawaii's Big Island burned about 1 percent of the state's total land, and other islands in the Pacific such as Palau, Saipan and Guam burn even more — up to 10 percent in some years.

On average, Guam has nearly 700 wildfires a year, Palau about 175 and Saipan about 20, reports data from 2018.

Guam, like many other places, has long used fire as a tool. Farmers sometimes use it to clear fields, and hunters have been known to burn areas while hunting illegally.

The U.S. territory's forestry⁵ chief Christine Camacho Fejeran said fires on the island are mostly caused by arson⁶, or illegal burning. "So, all of Guam's wildfires are human-caused issues, whether it's an intentional⁷ or an escaped backyard fire or another (cause)," she said.

On average, Fejeran said, 2,430 to 2,830 hectares of the island burn each year, amounting to about 5 percent of its land.

Back in Hawaii, Kumu Micah Kamohoalii said of a recent fire, "I've never seen a fire this big,"

Kamohoalii's family has lived in the area for many generations.

He suggested that the environment has changed during his lifetime.

"When I was young, all of this was always green," Kamohoalii said. "In the last 10 to 15 years, it has been really, really dry."

Trauernicht, the University of Hawaii wildfire expert, suggested that climate change is one of the reasons for the fires in Hawaii.

In addition to education and arson prevention, he said, changes in land use — such as reforestation that reduces some grasses — could help.

"It's within our control, potentially, to reduce the impacts that we're seeing with fires," Trauernicht said. "Both in terms of forest loss as well as the impacts on coral reefs."
