One of the major challenges to the human population is global climate change. The average surface temperature of the Earth has been rising over the past century as a result of global warming. Rising sea levels, hotter weather, heat stress, poorer air quality, population movement, and extreme weather events like floods, earthquakes, droughts, volcanic eruptions, tsunamis, etc. all have an influence on human health either directly or indirectly. Due to their high degree of exposure, the government's faulty management of the public health system, their poverty, etc., certain people are more susceptible to this shift than others. Age, gender, geography, malnutrition, and other variables may have a significant influence on public health. The spread of infectious diseases, such as those that are vector-borne, water-borne, etc., may be facilitated if we don't take action to regulate the already worsening global climate. Indirect consequences like population movement that cause stress, economic instability, house losses, etc. are also a major cause for worry. This essay examines the effects of global climate change on the environment, including the increased risk of death from extreme weather events, strategies for addressing these changes, perspectives on climate change from various nations, the vulnerability of low-income countries' populations, the economic instability brought on by climate change, and its effects on some nations, as well as the necessity of using sustainable and energy-efficient technology to safeguard the environment
