As shown in the article on how space exploration by humans, which raises issues, including providing nourishing food for future inhabitants on Earth's Moon, is accelerating scientific research on how to resolve world hunger on Earth, a growing problem due to the current trend of 65 million births per year! https://www.theworldcounts.com/populations/world/births
One way scientific research conducted in space improves life on Earth is through advancements in medical research and healthcare. The unique microgravity environment in space provides researchers with the opportunity to study biological processes and human physiology in ways that are not possible on Earth. Here are a few examples:
Bone and muscle health: Long-duration space missions, such as those on the International Space Station (ISS), have shown that astronauts experience significant bone and muscle loss due to the absence of gravity's normal load-bearing effects. Studying these changes helps researchers better understand bone diseases like osteoporosis and muscle atrophy, leading to the development of more effective treatments and interventions for these conditions on Earth.
Cardiovascular health: Space research has revealed that extended periods in microgravity can cause cardiovascular deconditioning in astronauts. Studying these effects helps scientists gain insights into the mechanisms of cardiovascular disease and develop strategies to counteract its progression. Additionally, the development of advanced medical devices and diagnostic techniques, such as remote monitoring and telemedicine, for use in space can have direct applications in remote or underserved areas on Earth.
Immune system function: The altered immune response observed in astronauts during space missions provides valuable information on how the immune system functions in extreme environments. This research contributes to our understanding of immune system dysfunctions and helps develop new approaches for disease prevention and treatment, including vaccines and immunotherapies.
Tissue engineering and regenerative medicine: Conducting research on tissue engineering and regenerative medicine in space can yield unique insights into cell growth, differentiation, and tissue development. The microgravity environment allows for the creation of three-dimensional tissue models that closely resemble human tissue structure and function. These advances can be applied to tissue engineering techniques on Earth, such as creating artificial organs or generating functional tissues for transplantation.
Environmental sustainability and technology: Research in space can lead to advancements in environmental sustainability and technology that benefit life on Earth. For example, studies on closed-loop life support systems and efficient resource utilization in space can inspire innovations in water and energy conservation, waste management, and sustainable agriculture on Earth.
These are just a few examples of how scientific research in space can have direct applications and improvements for life on Earth. The unique conditions and insights gained from space research can drive innovation across various fields and contribute to addressing global health challenges and enhancing our overall quality of life.
Much simpler ways are feasible here on Earth to improve life, rather than space and scientific research there, though, life on Earth is deteriorating around the Globe.
Isaac Asimov is among the few who have recognized the relevance and importance of space missions to environmentalism:
“Unless we are willing to settle down into a world that is our prison, we must be ready to move beyond Earth…. People who view industrialization as a source of the Earth's troubles, its pollution, and the desecration of its surface, can only advocate that we give it up. This is something that we can't do; we have the tiger by the tail. We have 4.5 billion people on Earth. We can't support that many unless we're industrialized and technologically advanced. So, the idea is not to get rid of industrialization but to move it somewhere else. If we can move it a few thousand miles into space, we still have it, but not on Earth. Earth can then become a world of parks, farms, and wilderness without giving up the benefits of industrialization.”
