Threats to Agriculture: Superweeds and Coordinated Attacks
This chapter explores agricultural challenges like superweeds and the risks of coordinated attacks on food supplies. It highlights the vulnerability of essential crops and the implications for global food security and calorie consumption.
What happens when civilisation faces its greatest tests?
This compilation brings together insights from researchers, defence experts, philosophers, and policymakers on humanity’s ability to survive and recover from catastrophic events. From nuclear winter and electromagnetic pulses to pandemics and climate disasters, we explore both the threats that could bring down modern civilisation and the practical solutions that could help us bounce back.
