Polar bears, the top predator in the Arctic, are facing a serious challenge to their survival due to melting glaciers caused by global warming. Their traditional habitat – unmelted ice or coastal areas – is dwindling. This is forcing polar bears to swim across distant open water in search of food and habitat, increasing the risk of drowning. In recent years, there has been a high incidence of drowning, especially among young bears, which are at greater risk of drowning due to their thinner fat layer and lower tolerance for cold water.
Polar bears are phototropic, and a moderate light source can help them navigate and find safe habitat. We have designed solar-powered luminescent devices that offer polar bears new hope for survival. These devices include solar buoys and glowing ice that provide navigational support in dark or low-light environments. By collecting solar energy and converting it into electricity, these devices provide polar bears with navigation reference points at night and in low visibility environments.
Combining solar technology and ecological design, the luminous ice blocks are buoyant and light-emitting, providing polar bears with navigational support and identification of safe areas at night and in low visibility environments. The design and layout of these devices take into account the natural migration routes and habitat distribution of polar bears, aiming to help them adapt to changes in the environment and find safe habitats.
Against the backdrop of global warming, the protection of polar bears is not only a necessity to protect this precious species, but also an inevitable requirement to maintain the ecological balance of the earth and sustainable development.
