Trees play a crucial role in sustaining human life by releasing oxygen through the process of photosynthesis. During this process, they absorb carbon dioxide from the atmosphere and utilize sunlight to convert it into energy, producing oxygen as a byproduct. This oxygen is essential for the respiration of humans and animals, making trees vital to our ecosystem. Moreover, they help improve air quality, store carbon, and provide habitats for countless species. By planting and protecting trees, we ensure that future generations continue to benefit from the life-sustaining oxygen they produce.
