Plants need sunlight, water, and air to grow. They make their own food through a process called photosynthesis. During this process, plants take in carbon dioxide and release oxygen into the air. This oxygen is very important for humans and animals to breathe. Plants also help keep our planet cool by providing shade. We should protect plants because they are essential for life on Earth.
