Part 5/10:
Ecological collapse represents a combination of climate change and biodiversity loss, culminating in phenomena like the Holocene mass extinction, where up to 90% of species could vanish. Anthropogenic climate change threatens food production, and many predicting a rise in global temperatures could trigger catastrophic ecological chain reactions.
4. Nuclear Winter
The threat of nuclear war remains a profound risk, albeit one that experts argue might have a lower likelihood today due to global interconnectivity. However, the potential destruction wrought by nuclear conflict extends beyond immediate deaths, leading to long-term agricultural collapse and drastic climate shifts due to atmospheric debris.
