Why is it important to research the deep sea
First, it helps us understand Earth’s history because many deep-sea rocks and sediments hold clues about past climates.
首先，研究深海能帮我们了解地球的历史，因为许多深海岩石和沉积物中，都藏着能揭示过去气候的线索。
Second, deep-sea creatures have special abilities. For example, they can make light by themselves, and they have special enzymes that work under high pressure. These can help medicine and technology.
深海生物有特殊的适应能力，比如会生物发光，还有能在高压环境下工作的酶，这些都能帮到医药和科技领域。
Most importantly, the deep sea helps control the global climate by taking in carbon dioxide.
最重要的是，深海能吸收二氧化碳，在调节全球气候方面发挥着关键作用。
How should everyone protect the deep sea
The deep sea is home to countless amazing creatures.
