Global warming, driven by human activities like deforestation and habitat destruction, is leading to an alarming rate of species extinction. This crisis is comparable to the catastrophic event that led to the dinosaurs' demise 65 million years ago, which was triggered by an asteroid impact. However, unlike that natural disaster, the current threat to biodiversity is primarily due to human actions that are altering the planet's climate.

In his book "An Inconvenient Truth: The Planetary Emergency of Global Warming and What We Can Do About It," Al Gore emphasizes that the current extinction crisis is self-inflicted rather than a result of an external celestial event. This highlights the urgent need for humanity to recognize its role in this environmental emergency and take meaningful steps to mitigate the damage caused by global warming and habitat destruction.
