Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student

A global catastrophic risk or a doomsday scenario is a hypothetical future event that could damage human well-being on a global scale,[2] even endangering or destroying modern civilization.[3] An event that could cause human extinction or permanently and drastically curtail humanity's potential is known as an "existential risk."[4]

Over the last two decades, a number of academic and non-profit organizations have been established to research global catastrophic and existential risks, formulate potential mitigation measures and either advocate for or implement these measures.[5][6][7][8]
