「食料安全保障と海洋環境：迫りくる脅威」の英語長文問題

The global community faces a confluence of interconnected challenges threatening food security and the health of our oceans. Rising sea levels, driven by climate change, are inundating coastal farmlands, turning fertile soil into saline wastelands unsuitable for agriculture. This directly impacts food production, particularly in low-lying, densely populated regions heavily reliant on coastal agriculture. Simultaneously, marine pollution, stemming from plastic waste, chemical runoff, and unsustainable fishing practices, degrades ocean ecosystems. Overfishing depletes fish stocks, a critical food source for millions worldwide. Damaged coral reefs, vital nurseries for many commercially important fish species, further exacerbate the problem. The resulting decline in marine biodiversity has profound implications for food security, not only reducing the availability of seafood but also disrupting delicate marine food webs. The intricate relationship between food security and ocean health is often overlooked. While the immediate impact of rising sea levels on agriculture is evident, the long-term consequences of ocean pollution are equally severe. The decrease in fish stocks necessitates the intensification of aquaculture, often with detrimental consequences for surrounding ecosystems. The use of chemicals and antibiotics in intensive farming practices further contributes to marine pollution, creating a vicious cycle. Addressing these interconnected challenges requires a comprehensive, integrated approach involving sustainable agricultural practices, stringent regulations on pollution, and responsible fishing methods. International cooperation and technological innovation are crucial in mitigating these risks and securing a sustainable future for both food production and ocean health. Failure to do so will not only endanger food security for billions but will also lead to irreversible environmental damage and social unrest.
