Increase in human populations in the Galapagos Islands has led to habitat disturbance and overexploitation of resources, threatening native species like giant tortoises and causing invasive species to disrupt ecosystems. Conservation efforts are underway, including sustainable management practices like culling non-indigenous species and creating marine reserves to protect the unique biodiversity of the islands.
