Phys · · 962 words · By Benjamin Selwyn
Global Food Insecurity Socio-economic Inequality climate_change Agricultural Reform

The article discusses how a 'super El Niño' event, combined with climate change and geopolitical instability, threatens global food security. The author argues that the current industrial, livestock-heavy agricultural system is fragile and advocates for a transition toward agroecological, plant-based farming to increase resilience.
