1. Antimicrobial Resistance

Antimicrobial resistance occurs when bacteria, viruses, fungi, or parasites evolve to survive exposure to the drugs designed to kill them. The emergence of drug-resistant pathogens represents one of the most significant threats to global health, rendering previously treatable infections potentially fatal. The World Health Organisation estimates that antimicrobial resistance directly causes 700,000 deaths per year worldwide, a number that could rise to 10 million by 2050 without urgent action. Overuse and misuse of antibiotics in human medicine and animal agriculture has accelerated the pace of resistance, while the pipeline of new antimicrobial drugs has slowed significantly.

2. Social Media and Mental Health

The relationship between social media use and mental health has attracted significant scientific and public attention. Numerous studies have found associations between heavy social media use and higher rates of anxiety, depression, and loneliness, particularly among adolescents. Researchers propose several mechanisms: constant exposure to idealised portrayals of others’ lives fosters social comparison and reduces self-esteem; cyberbullying is more pervasive and harder to escape than face-to-face bullying; and the variable reinforcement schedule of social media platforms can generate compulsive use patterns that displace sleep and real-world social interaction.

3. Plate Tectonics

The theory of plate tectonics revolutionised the earth sciences, providing a unified framework for understanding geological phenomena from earthquakes and volcanoes to the formation of mountains and ocean basins. The Earth’s outer shell, the lithosphere, is divided into rigid plates that move relative to one another at speeds of a few centimetres per year. Where plates collide, one may be forced beneath the other in a process called subduction, generating earthquakes and volcanic activity. The movement of plates over hundreds of millions of years has shaped the distribution of continents and oceans that we see today.

4. Food Security

Food security exists when all people, at all times, have physical and economic access to sufficient, safe, and nutritious food to meet their dietary needs. Despite significant advances in agricultural productivity over the past century, an estimated 820 million people worldwide remain chronically undernourished. Food insecurity is driven by a complex interplay of factors, including poverty, conflict, climate change, water scarcity, and post-harvest losses. Achieving global food security will require increases in agricultural output, improvements in distribution, reductions in food waste, and shifts in dietary patterns towards more sustainable foods.

5. Language Extinction

Of the approximately 7,000 languages spoken in the world today, linguists estimate that roughly half will disappear within this century. Languages become extinct when communities shift to using a more dominant language, driven by economic incentives, social pressure, migration, or political marginalisation. When a language dies, the world loses not just a communication system but a unique way of encoding knowledge about the natural world, cultural practices, oral literature, and identity. Efforts to revitalise endangered languages include educational programmes, production of media content, and documentation by linguists while living speakers remain.
