There are three people visible in the image. They appear to be engaged in some activity, possibly related to the mangrove roots. The person on the left is wearing a light-colored shirt and appears to be standing near a wooden structure. The person in the middle is dressed in a dark-colored shirt and is holding what looks like a tool or equipment. The person on the right is also dressed in a dark shirt and is holding a similar tool or equipment. All three individuals seem to be focused on their task.
