This book covers environmental challenges, their origins, and potential solutions. Environmental concerns have a negative impact on humans, plants, animals, and the bioenvironment. At the individual, organizational, or state level, environmental protection is the action of safeguarding the environment for the benefit of people and the environment. The carbon dioxide equivalent of greenhouse gases in the atmosphere has already crossed 400 parts per million, with a total "long-term" GHG above 455 parts per million . There is a possibility that the level of greenhouse gases in the atmosphere is greater than what could eventually trigger climate change. The climate change is a real threat. Humanitarian needs are increasing, and this is the primary driver. Extreme weather caused massive devastation and affected a huge number of people. Furthermore, there are currently 4,444 more weather disasters per year. Weather-related disasters now account for about 70% of all disasters, up from 50% two decades ago. This book covers the full field of environmental science. This book discusses the transformation of atmospheric carbon dioxide into platform chemicals, the adsorption of heavy metals on natural adsorbent surfaces, the photocatalytic degradation of dyes, the causes of environmental pollution, sustainable development, waste water treatment by natural adsorbents, eco-friendly hotel tourism, and the emergence ofnanotechnology for environmental protection.
