Sunday's Planet Earth II featured a deeply emotional moment where viewers saw hawksbill turtle hatchlings leaving their nests on a beach in Barbados, heading inland instead of into the sea.
Why? Light pollution. The turtles are supposed to follow the light from the full moon to find the sea, but are confused and head in the wrong direction.
As a result many turtles are killed each night by traffic or simply die from exhaustion.
In the show, David Attenborough said that as many as 80% of the turtles are distracted by the lights near the beach.
Or are attacked by crabs at the top of the beach.
Many viewers became distressed by the sequence and wished that someone had saved them.
However, BBC Earth immediately tweeted that every turtle featured in the episode was rescued.
Planet Earth II worked with the Barbados Sea Turtle Project, which rescues turtles and releases them back into the sea during the hatching season.
In a video published on the BBC website, Carla Daniel, the organisation's deputy field director, spoke about why it was necessary to help the turtles.
This doesn't mean that every turtle was saved, but at least there is some help for them out there.
