From the Perspective of A Little Squirrel, Looking at the Big City

This paper explores how urban squirrels can be used as indicators of various urban conditions from the perspective of small squirrels. Squirrels are adorable wild animals, and their habits and survival methods are essential for humans to live in harmony with them. Scientific studies have shown that urban squirrels can reflect the quality of the urban ecological environment, the health of the ecosystem, the state of environmental pollution, climate change, and the harmonious coexistence of man and nature. Squirrels need suitable habitats, adequate food and water, and their behaviour and habits can provide a wealth of information about the health of urban ecosystems. In addition, squirrels are very sensitive to environmental pollution, and their health status and behavioral changes can be used as early warning signs of urban environmental pollution. By observing the squirrel's reproductive cycle and food storage behavior, we can also understand the impact of climate change on urban ecosystems.
