Hannah Gelbart: 我主持了这个关于人工鱼礁的讨论，特别是关于一艘巨型邮轮将被故意沉入海底，成为世界上最大的一个人工鱼礁。我们讨论了人工鱼礁对海洋环境的影响，包括其对生物多样性、旅游业和渔业的潜在益处，以及可能存在的环境风险和必要性问题。我们还探讨了人工鱼礁的各种类型，以及它们对海洋生物的实际帮助。 我的主要观点是，我们需要权衡人工鱼礁的利弊，并考虑其对海洋生态系统的长期影响。虽然人工鱼礁可能在短期内促进海洋生物的生长，并吸引游客，但我们必须确保其建造和使用方式不会对环境造成负面影响，例如污染或入侵物种的传播。我们还应该优先保护现有的自然海洋环境，而不是仅仅依赖人工鱼礁来解决海洋生态问题。 Georgina Ranard: 我是气候和科学记者，在这个播客中，我解释了将船只改造成人工鱼礁的过程，以及旧船只是否对海洋生物有益。我详细介绍了将一艘巨型邮轮改造成人工鱼礁的具体步骤，包括清除污染物、准备沉船以及潜在的风险。 我强调了人工鱼礁的双重目的：改善海洋环境并促进旅游业。然而，我也指出，人工鱼礁的建造和使用方式至关重要，必须选择对环境友好的材料，避免污染。此外，我还讨论了人工鱼礁的各种类型，包括专门设计的人工结构和利用废弃物建造的人工鱼礁，并分析了它们对海洋环境的短期和长期影响。我总结说，人工鱼礁不能替代天然珊瑚礁，保护现有海洋环境仍然至关重要。

The podcast discusses the SS United States, a large ocean liner being sunk to become the world's largest artificial reef. While proponents claim it will boost biodiversity and tourism, concerns remain about potential toxicity and the overall effectiveness of artificial reefs.
  • SS United States to be sunk as artificial reef
  • Concerns about potential toxicity
  • Project aims to improve marine environment and boost tourism

Shownotes Transcript

An enormous fifty-year-old ocean liner, the SS United States, is set to be sunk and become the world’s biggest artificial reef, off the coast of Florida in the US. The area already has over 500 artificial reefs. These are manmade structures that may mimic some of the characteristics of a natural reef. The people behind it say it’ll improve biodiversity, local tourism and fishing.

And it’s not just old ships; people have sunk oil rigs and subway carriages. They don’t always have a positive effect; in the 1970s two million tyres were dropped into the ocean to try to create an artificial reef (also off the coast of Florida), but they released lots of toxins.

Climate and science reporter Georgina Rannard explains how ships like this get turned into artificial reefs and whether old ships are good for marine life. We talk about other kinds of artificial reefs and ask what benefits they can have for our oceans.
