Trees can survive without humans but humans cannot survive without trees.why?

Trees play a vital role in maintaining the Earth's ecosystem by producing oxygen, sequestering carbon dioxide, and providing habitat for countless species. They contribute to soil health, water cycles, and climate regulation, all of which are essential for human survival. While trees can thrive independently in nature, humans rely on them for clean air, food, and resources. Thus, while trees can exist without humans, our well-being is intricately linked to their health and survival.
