Practice Responsible Ecotourism: Ecotourism can bring in much-needed funds for wildlife conservation, but only when done the right way. Avoid activities that could harm animals or their habitats, and never approach or touch wild animals. 4.

Participate in Wildlife Surveys: Many conservation organizations conduct wildlife surveys to monitor populations and habitats of endangered animals, and volunteers are always welcome. 7. Advocate for Wildlife-Friendly Policies: Make your voice heard by contacting your elected representatives and supporting policies that protect endangered species.

answer:One disadvantage of using solar energy is its dependence on weather conditions and the availability of sunlight. During cloudy or rainy days and at night, the output of solar panels drops significantly, which can interrupt the energy supply. This requires the implementation of storage systems or the use of backup energy sources, which can increase the overall cost of the system.
