文章大意:本文为一篇说明文。核污染是一个严重的全球问题。研究表明,人类的活动对海洋环境产生了重大威胁,日本排放核污水事件引起了全球的反对,因此,迫切需要进一步研究和采取缓解措施,以解决核污染对环境和人类健康的广泛影响。
1 . Nuclear pollution is a serious global ___________, brought to the forefront by major accidents at Three Mile Island, Chernobyl, and Fukushima. These events have demonstrated the significant health and environmental risks _________by nuclear disasters. Not only have they caused immediate health problems, such as radiation sickness and increased cancer rates, but they have also _________lasting environmental damage and genetic changes in affected communities. As a result, nuclear pollution remains a pressing concern for governments, scholars, and individuals worldwide.
When nuclear accidents occur in coastal areas, the _________environment becomes a critical concern due to the crucial role that oceans play in _________the climate, ensuring food security, and supporting the livelihoods of billions of people globally. In recent years, the increasing threats to marine ecosystems from ocean pollution have _________public awareness of the need to protect the marine environment. Studies have shown that human activities pose a _________threat to marine environments, emphasizing the importance of improving environmental management and taking measures to mitigate environmental risks.
Following the Fukushima nuclear disaster in 2011, efforts to cool the reactors by pumping in seawater resulted in the _________of a significant amount of nuclear waste in the water storage tank at the Fukushima Nuclear Power Plant. _________attempts to manage this waste, the Japanese government’s decision to release nearly 1.26 million tons of nuclear wastewater into the Pacific Ocean over the next 40 years has faced opposition __________neighboring countries, local ____________, and international environmental organizations.
This __________poses serious risks to marine life, fisheries, and human health. Radioactive isotopes present in the wastewater, such as tritium, carbon-14, cobalt-60, and strontium-90, can accumulate in marine organisms and ultimately affect human populations through the food ____________. Therefore, there is an/a ____________need for further research and mitigation measures to __________the widespread impacts of nuclear pollution on the environment and human health.
