The Arctic is a sensitive environment that needs our protection. It is home to many animals, such as polar bears, seals and narwhals. These animals depend on the cold temperature and ice for their survival.
However, the Arctic is facing many challenges. Climate change is causing the ice to melt faster than it can form. When ice melts, the arctic animals will be hard to find food. It affects not only the animals but also the people who live there. They rely on the ice for hunting and travelling. To protect the Arctic, we must reduce the number of greenhouse gases. This can be done by using less energy, walking or biking instead of driving, and recycling more.
