What does nature must left untouched to reserved its balance?

Nature must be left untouched in its ecosystems, including forests, wetlands, and oceans, to maintain biodiversity and ecological balance. Human activities such as deforestation, pollution, and urban development disrupt these systems, leading to habitat loss and species extinction. Preserving natural habitats allows for the natural processes of regeneration and adaptation, ensuring that ecosystems can function effectively. Protecting these areas is crucial for sustaining the planet's health and resilience.
