Why are leaves ecologically and human-relevant?

Leaves play a vital role in both ecological systems and human activities, primarily due to their diverse functions and contributions. One of the key reasons they are ecologically and human-relevant is because they are sources of medicine, beverages, and insect repellents.

In ecology, leaves are integral to the process of photosynthesis, where they convert sunlight into energy for the plant while releasing oxygen, which is essential for all aerobic life. Beyond that, many leaves from different plant species have been identified for their medicinal properties; for example, willow leaves contain compounds that can be used in pain relief, and various herbs provide anti-inflammatory effects or even act as natural remedies for a range of ailments.

Additionally, leaves are commonly used in beverages, with tea leaves being one of the most notable examples.
