The emergence of infectious pathogens with epidemic and pandemic potential like “Severe acute respiratory syndrome (SARS), middle east respiratory syndrome (MERS), influenza, Ebola, Marburg, Lassa, Nipah, and Zika for the last 30 years, and the current COVID-19 disease caused by coronavirus-2 (SARS-CoV-2), is highly infective, causing severe acute, long-term illness that affects the global public health and economic threats”. Still, now no ‘Buster-Dose-Vaccine’ is discovered. On the other hand, food production forests, agriculture, and horticulture significantly reduce different pest attacks. So, to tackle and overcome both, the naturally growing “Wildlife-Conservation-Project of ‘Wild Barn Owl and Bats’ in the two Heritage-Schools” forming a ‘Complex-Typical-Ecosystem’ in the food-chainrelationships- landscaping, controlling the different pests in the forest, horticulture, agriculture, and pisciculture, etc., increasing food production, but also plays a vital role in preventing COVID-19, the high rate of morbidity and mortality, showing the “Wild Barn Owls and Bats Act as a Future Preventive Epidemic COVID-19 Model”, and developing policy initiative potentially life-saving therapies by boosting natural immunities of the different communities of Burdwan Municipality, West Bengal, India, and wildlife conservation may be the “Wild Owls and Bats Act as Future Wild X-Disease Preventive COVID-19 Non-Medicated Vaccine: Improved Global-Health Forestry-Agriculture-Environment Science- Technology-Communication”, and worlds become retained in old form developing education and research in the new normal situation. It needs the “Wildlife Conservation Approach” with human, animal, and environmental interactions that may prevent any kinds of "X-Disease" in the future.
