Đề thi VSTEP Full C1 — Antimicrobial Resistance & Climate Migration (mẫu 4)

Antimicrobial resistance (AMR) has emerged as one of the most pressing public health challenges of the 21st century. A landmark study published in 2022 estimated that bacterial AMR was directly responsible for nearly 1.3 million deaths worldwide, with the burden disproportionately affecting low- and middle-income countries. The phenomenon occurs when microorganisms evolve mechanisms to withstand the drugs designed to eliminate them, rendering standard treatments ineffective. Researchers have identified several drivers of accelerated resistance, including the overuse of antibiotics in clinical settings, the routine administration of antimicrobial agents in livestock production, and the proliferation of resistant strains through global travel and trade networks. Recent genomic analyses have revealed that resistance genes can transfer horizontally between bacterial species, compounding the difficulty of containment. In response, the scientific community has adopted a multi-pronged strategy. This includes the development of bacteriophage therapies, the re-examination of underutilized compounds, and the implementation of stricter stewardship programs. However, critics argue that without coordinated international policy and substantial funding, these efforts may prove insufficient against what some have termed the 'silent pandemic.'

Good morning, everyone. Today's lecture examines the complex relationship between climate change and human displacement. While we often associate migration with economic or political factors, environmental drivers are increasingly shaping population movements worldwide. According to recent estimates from the Internal Displacement Monitoring Centre, approximately 26.4 million people were displaced by weather-related events in a single recent year. This figure excludes those fleeing gradual environmental degradation, such as desertification or sea-level rise, which may account for an even larger number of so-called 'climate migrants.' The impacts are far from uniform. Island nations like Tuvalu and Kiribati face existential threats as rising oceans threaten to submerge their territories entirely. Meanwhile, in regions such as the Sahel, prolonged droughts have eroded agricultural livelihoods, forcing rural communities toward urban centers that are often ill-equipped to absorb them. Importantly, international law currently lacks a formal framework for protecting climate-displaced persons. The 1951 Refugee Convention does not recognize environmental factors as grounds for asylum, leaving millions in legal limbo. Addressing this gap will require unprecedented cooperation between governments, international organizations, and civil society.
