The frozen bunny corpses are transported to a heating plant in central Sweden, where they're incinerated to heat homes.

"Those who support the culling of rabbits think it's good to use the bodies for a good cause," said Anna Johanneson of the Society for the Protection of Wild Rabbits.

"But it feels like the power company is trying to turn the animals into an industry rather than look at the main problem," Officials target the rabbits to stem the damage done from their feasting on the parks' plants.

Last year, 6,000 rabbits were killed, the paper reported.

Activists claim it's not only wild rabbits being harvested, but also unwanted pets turned loose in Stockholm's parks.

Johannesson told a local newspaper it's time Swedish parks authorities started thinking outside the hutch for ways to co-exist with the bunnies.

"Helsinki in Finland sprays the plants to make them unappetizing and they have also set up a system of shelters for animals to be donated to," she said.

"They have come much further along than us."
