Trees are often called the lungs of Earth—and for good reason. Just as lungs take in oxygen and release carbon dioxide, trees absorb carbon dioxide from the air and release oxygen through the process of photosynthesis. This vital exchange helps maintain the balance of gases in our atmosphere, making life on Earth possible.

Beyond producing oxygen, trees play a crucial role in fighting climate change. They act as natural carbon sinks, storing large amounts of carbon that would otherwise contribute to global warming. A single mature tree can absorb up to 22 kilograms (about 48 pounds) of carbon dioxide per year.

Trees also help clean the air by trapping pollutants like dust, smoke, and harmful gases. They cool cities by providing shade and releasing moisture into the air, reducing the need for air conditioning. Their roots prevent soil erosion, and their canopies provide shelter for countless species of animals and insects.

In short, trees do much more than just stand tall and look beautiful—they sustain life. Protecting and planting trees is one of the simplest yet most effective actions we can take to preserve our planet for future generations.
