全球气候变化引起了全世界的关注。海洋是地球上最大的活跃碳库，在全球气候变化中发挥着重要作用。然而，由于全球塑料的大量消耗和管理不善，海洋塑料污染日益严重。海洋塑料对负责海洋二氧化碳气体交换和循环的生态系统的影响可能会导致更多的温室气体排放。因此，本文讨论了海洋微塑料对海洋固碳的威胁。海洋微塑料可以1)影响浮游植物的光合作用和生长；2)对浮游动物有毒害作用，影响其发育和繁殖；3)影响海洋生物泵；4)影响海洋碳储量。浮游植物和浮游动物是海洋最重要的生产者和消费者。因此，显然需要进一步的研究来探索这种影响的潜在规模和范围及其潜在机制。
Global climate change has attracted worldwide attention. The ocean is the largest active carbon pool on the planet and plays an important role in global climate change. However, marine plastic pollution is getting increasingly serious due to the large consumption and mismanagement of global plastics. The impact of marine plastics on ecosystem responsible for the gas exchange and circulation of marine CO2 may cause more green-house gas emissions. Consequently, in this paper, threats of marine microplastics to ocean carbon sequestration are discussed. Marine microplastics can 1) affect phytoplankton photosynthesis and growth; 2) have toxic effects on zooplankton and affect their development and reproduction; 3) affect marine biological pump; and 4) affect ocean carbon stock. Phytoplankton and zooplankton are the most important producer and consumer of the ocean. As such, clearly, further research should be needed to explore the potential scale and scope of this impact, and its underlying mechanisms.
