Thank You for Helping Us Build Sloth Speedways!
A World Environment Day Letter from All of Us at The Sloth Institute
Dear Team Sloth,
We’re still excited—thanks to you, our World Environment Day Sloth Speedway fundraiser was a wild success!
Because of your generosity, we surpassed our $8,000 goal and raised an incredible $8,169.16 to build life-saving Sloth Speedways in Costa Rica’s rainforests. That means more rope bridges in the treetops, safer passage for our slow and sweet friends, and fewer tragic encounters with powerlines, roads, and predators.
What Are Sloth Speedways?
Sloth Speedways are rope bridges designed to reconnect fragmented rainforest canopies. These “wildlife highways” allow sloths, monkeys, kinkajous, and other arboreal animals to move safely across their natural habitat without ever touching the ground. By keeping sloths off dangerous roads and away from electrocution risks, these speedways are a proven and essential tool in our fight to reduce preventable deaths.
Just this past month, we shared the heartbreaking story of a pregnant sloth who suffered fatal electrocution injuries. A Sloth Speedway could have entirely prevented her loss. You showed up, and you made sure her story led to change.
World Environment Day Fundraiser Highlights:
Total Raised: $8,169.16
Total Donors: 60 wonderful supporters
Most Popular Option: “Sprint” – funding 35 meters of rope per gift
Biggest Giving Days: May 26 and June 5 (World Environment Day!)
Recurring Gifts: One generous monthly donation of $65
Biggest Single Gift: $2,200 – Thank you, Mr. Bird!
Each donation adds real meters of rope into the forest canopy, creating a network of safety for generations of sloths to come. And the impact doesn’t stop here: the materials, installation, monitoring, and maintenance of these Sloth Speedways will be powered by the funds you helped raise.
You didn’t just help sloths. You helped monkeys, possums, anteaters, porcupines, and an entire ecosystem.

From the Whole Team at The Sloth Institute:
We are so grateful to every single one of you who donated, shared the campaign, told a friend, or cheered us on. Your kindness made this dream a reality.
And this is just the beginning. We’ll share updates soon as new speedways because of you. Thank you for taking action to protect Costa Rica’s wildlife and for believing in a world where sloths can live wild and free.
With muddy boots and full hearts,
The Sloth Institute Team
