「液状化対策、プラスチック問題、そして食物連鎖：複雑に絡み合う現代社会の課題」の英語長文問題

The 2011 Great East Japan Earthquake highlighted the devastating effects of soil liquefaction, particularly on coastal communities. Buildings collapsed, infrastructure crumbled, and the environment suffered irreparable damage. Liquefaction mitigation strategies, ranging from ground improvement techniques to stricter building codes, have been implemented since then. However, these measures often involve significant costs and may not be universally applicable. Meanwhile, the global plastic crisis continues to escalate. Vast quantities of plastic waste pollute oceans and landfills, harming marine life and ecosystems. The production of plastics, often derived from fossil fuels, contributes significantly to greenhouse gas emissions, exacerbating climate change, a factor which can also influence the severity of liquefaction. Furthermore, the implications extend to the intricate web of the food chain. Microplastics, resulting from the breakdown of larger plastic debris, are ingested by marine organisms. These toxins bioaccumulate, moving up the food chain and potentially affecting human health. The use of certain chemicals in plastic production can also contaminate soil and water sources, indirectly impacting agricultural practices and food security. The interconnectedness of these seemingly disparate issues – liquefaction, plastic pollution, and food security – presents a complex challenge for policymakers and scientists alike. Finding sustainable solutions requires a holistic approach, integrating technological advancements with effective policy interventions and a shift toward responsible consumption habits. Balancing economic considerations with environmental protection and public health demands careful planning and international cooperation.
