This book outlines a spectrum of risks and threats confronting humanity since the inception of the Russo-Ukrainian war. As the conflict intensifies, the global community closely monitors developments in Ukraine with growing apprehension. A primary concern stemming from the Russian invasion is the heightened risk of environmental disasters. International organizations express profound worry that this war may trigger various environmental and ecological catastrophes. A pressing question emerges: Could the Chernobyl tragedy be replicated, and is there a potential for another nuclear accident in Ukraine? The ongoing conflict raises the stakes for such a recurrence, especially considering the repeated bombings of nuclear power plants since the invasion. A notable example is the Zaporizhzhia Nuclear Power Plant, ten times more powerful than Chernobyl. The core objective of this book is to foster awareness of the threats and risks facing humanity since the onset of the Russo-Ukrainian war.
