Pornhub wants to do its part to help the environment.

Last Friday—Arbor Day— the free porn site launched an initiative to plant a tree for every 100 videos viewed in the site's—ahem—"large tree" category. The safe-for-work counter site for the Arbor Day celebration says users have already helped plant over 12,000 trees. You do the math.

"This Arbor Day Pornhub will do what it does best and give America some serious wood by donating 1 tree for ever 100 videos viewed in our Big (expletive) category," the promotional site reads. "The more videos that are viewed, the more trees we will plant!"

It hasn't been revealed where the trees will be planted or what environmental group the website will go through to organize the planting, The Daily Dot reported.

A PR director for Pornhub said the site is considering three potential groups: Arbor Day Foundation, Trees for the Future or American Forests, Mashable reported.

"At Pornhub, we give a countless amount of wood every day," Pornhub representative Mike Williams told Mashable. "Playing off that, we saw an opportunity to promote our brand and give back to the community."

Pornhub has similarly themed promotions before, including one for Breast Cancer awareness month in 2012 where they donated money for clicks on certain other categories.

This initiative ends May 2 at midnight.

"Whatever the species, our trees will grow up to be long and hard and, with any luck, they will go on to spread seed of their own," Williams said.
