National parks play a crucial role in biodiversity conservation by providing protected habitats for a diverse range of plant and animal species. They act as safe havens for wildlife populations, allowing them to thrive without the threat of habitat destruction or human interference. Additionally, national parks help to preserve ecosystems and promote ecological balance by maintaining natural processes and preserving key habitats. Conservation efforts within national parks also help to raise awareness about the importance of biodiversity and the need to protect our natural heritage for future generations.
