But these tall, quiet plants are true heroes of our planet—they do far more than just make our world look beautiful. ②First and foremost, trees are the Earth’s lungs. They take in carbon dioxide, a greenhouse gas that warms the planet, and turn it into oxygen, the air we need to breathe. A single mature tree can produce enough oxygen for four people in one day! They also cool the air around them: the shade from trees can lower summer temperatures by 3–5 degrees Celsius, making our cities more comfortable places to live. ③Trees are also home to millions of living things. Birds build nests in their branches, squirrels store food in their hollows, and insects hide under their bark. Many animals depend on trees for food too—think of the fruit, nuts, and leaves that feed forest creatures. Without trees, countless species would lose their habitats and face extinction. ④Besides helping the environment, trees are useful to humans in many ways. We use wood to make furniture, paper, and even buildings. Some trees give us medicine: the bark of the willow tree, for example, was the original source of aspirin. Trees also help prevent natural disasters. Their roots hold soil together, which stops landslides, and they absorb rainwater, reducing the risk of floods. ⑤Sadly, we are losing trees at an alarming rate. Every year, humans cut down around 15 billion trees, mostly to make space for farms and cities. Deforestation not only destroys animal habitats, but also speeds up climate change and increases air pollution. The good news is that everyone can help protect trees. Planting a tree, saving paper, and supporting forest protection laws are all small but important steps we can take. Trees are silent, but they speak volumes about the health of our planet. It’s time we stopped overlooking these heroes and started caring for them—for our sake, and for the sake of future generations. 1.
