Prospects of Nanotechnology to Mitigate Global Challenges of Climate Change and Public Health

Abstract

Nanotechnology holds immense promise in mitigating the intertwined global challenges of climate change and public health by offering high-efficiency nanomaterials that enable innovative, efficient, and often sustainable solutions. Climate change, acknowledged as one of the most critical global public health crises, has led to extreme weather events and caused thousands of deaths annually, particularly in economically deprived areas. There is a significant increase in global warming due to human intervention and the uncontrolled use of technology in all areas of life. Climate change also increases the occurrence and transmission of pathogens that pose a threat to human life. Extreme heat can cause a variety of illnesses, including cardiovascular events. Temperature and seasonal variations raise the danger of waterborne illnesses and can introduce new diseases to large regions. Eco-friendly and effective methods, materials, and procedures are needed to reduce and manage climate change and its health effects. This review addresses recent developments in nanotechnology with potential benefits to combat climate change and public health. Despite several advantages, there are still significant obstacles to its use into public health and climate change mitigation. Although nanotechnology shows great promise in reducing the negative health effects of climate change, more research should be done on thorough safety assessments, economical production techniques, and ways to reduce long-term environmental and health impacts to guarantee its responsible and sustainable use.
