| Summary: | The Coronavirus-19 (Covid-19) disease pandemic has caused a widespread, tragic, human, and life disaster and reduced the activity of billions of people on this earth. However, it has also been able to heal the earth's environment in our universe. The decline in human activity has resulted in a sharp reduction in pollution and marked clean air. This effect is far more dramatic than any systematic anthropogenic effort to reduce the impact of emissions. Air pollution caused by human activities has been relatively halted so that a clear, healthy blue sky is felt again. The pollution index, air quality, and the earth's environment are getting better. This condition further proves that the destruction of the earth and global warming is 95 due to human greed as a leader on this earth. Tropical ecosystems have a high and optimal temperature, sunlight intensity, rainfall, and organic cycles throughout the year, so they have the world's highest growth rate and biodiversity. However, the bio-economic value is still meager due to the local community's socio-economic pressure, and it has not been managed professionally. An integrated organic-cycle cultivation system based on the universe's nature could have superior bio-economic prospects in managing tropical natural resources cured by Covid-19. © 2023 Elsevier Inc.
