塑料污染如何影响海洋生物多样性
塑料污染如何影响海洋生物多样性当我们漫步在海滩，享受着海风的吹拂和阳光的温暖时，可能很难想象，那看似平静美丽的海洋深处，正遭受着塑料污染的严重威胁。
塑料，这个在日常生活中无处不在的材料，已经成为了海洋生态系统的一大“杀手”，对海洋生物多样性产生了深远且恶劣的影响。
塑料污染对海洋生物的直接危害可谓触目惊心。
大量的塑料垃圾漂浮在海面上，形成了所谓的“塑料汤”。
许多海洋生物会误将这些塑料当作食物吞食。
例如，海龟可能会把漂浮的塑料袋误认为是它们喜爱的水母，而海鸟则可能把塑料碎片当作鱼虾吞入腹中。
这些塑料在它们的体内无法被消化，长期积累下来，会阻塞消化道，导致它们无法正常进食，最终饥饿而死。
除了误食，塑料垃圾还会缠绕海洋生物，给它们带来致命的伤害。
鲸鱼、海豚等大型海洋哺乳动物可能会被废弃的渔网、绳索等缠住，限制它们的活动能力，甚至造成身体的创伤和感染。

塑料污染如何影响海洋生物多样性在我们广袤的蓝色星球上，海洋占据了约 70%的面积。
海洋不仅是地球上生命的摇篮，也是无数生物繁衍生息的家园。
然而，如今塑料污染正成为威胁海洋生态系统和生物多样性的重大危机。
塑料，这种曾经被视为便利和创新的材料，如今却在海洋中泛滥成灾。
大量的塑料制品，从微小的塑料颗粒到巨大的塑料垃圾，都在不断地进入海洋。
这些塑料垃圾的来源多种多样，包括但不限于日常生活中的塑料制品、渔业活动中的废弃渔具、以及工业生产中的塑料废弃物。
塑料污染对海洋生物多样性的影响是多方面的，且极其严重。
首先，塑料垃圾会直接威胁到海洋生物的生命安全。
许多海洋生物会误将塑料当作食物吞食。
例如，海龟可能会把漂浮在海水中的塑料袋误认为是水母，吞食后这些塑料会在它们的消化道内积聚，导致无法正常进食和消化，最终死亡。
同样，海鸟也会把塑料碎片当作食物喂给幼鸟，从而影响幼鸟的生长和存活。
除了误食，海洋生物还可能被塑料垃圾缠绕束缚。
废弃的渔网、塑料绳等常常会缠住海洋生物，如海豹、海豚和鲸鱼等。
这些缠绕会限制它们的行动，造成身体的损伤和感染，严重时甚至会导致窒息和死亡。
曾经就有报道，一只被塑料绳紧紧缠住的海豹，由于长期无法挣脱，最终身体被勒出深深的伤口，直至死亡。
塑料污染还会间接地影响海洋生物的生存环境。
塑料在海洋中会逐渐分解成微小的颗粒，被称为“微塑料”。
这些微塑料会吸附海水中的有毒化学物质，如重金属和有机污染物。
当海洋生物摄入这些微塑料时，也就同时摄入了附着在上面的有毒物质，这会对它们的生理机能造成损害，影响生殖、发育和免疫系统。
而且，微塑料在海洋食物链中的传递也令人担忧。
从浮游生物到小型鱼类，再到大型海洋生物，微塑料可能会在食物链中不断积累和放大，对整个海洋生态系统的健康产生潜在的长期影响。
塑料污染对海洋生物栖息地的破坏也不容忽视。
例如，塑料垃圾在海滩上的堆积会影响潮间带生物的生存空间，破坏它们的繁殖和觅食场所。
在珊瑚礁生态系统中，塑料垃圾的覆盖会阻碍珊瑚的光合作用，影响珊瑚的生长和健康，进而影响依赖珊瑚礁生存的众多生物。
塑料污染如何影响海洋生态
塑料污染如何影响海洋生态在我们的日常生活中，塑料已成为无处不在的材料。
从包装材料到日常用品，塑料的使用极其广泛。
然而，当这些塑料被随意丢弃后，它们中的很大一部分最终进入了海洋，给海洋生态系统带来了严重的危害。
塑料垃圾进入海洋的途径多种多样。
沿海地区的垃圾处理不当，河流将陆地上的塑料带入海洋，甚至海上的船只和石油平台也会排放塑料废弃物。
一旦塑料进入海洋，它们就开始了漫长的“破坏之旅”。
首先，塑料会对海洋生物造成直接的物理伤害。
大量的塑料瓶、塑料袋、塑料绳等漂浮在海面上，海洋动物可能会被这些塑料物品缠住。
例如，海龟可能会被塑料绳缠住四肢，无法游动，最终导致死亡；海豹可能会被塑料环卡住头部，影响进食和呼吸。
还有一些海洋生物会误将塑料当作食物吞食。
塑料在它们的体内无法消化，会阻塞消化道，导致营养不良甚至死亡。
科学家们在许多海洋生物的体内都发现了塑料碎片，从微小的浮游生物到巨大的鲸鱼，无一幸免。
其次，塑料在海洋中的分解过程也会带来严重的问题。
塑料在海洋中的降解速度非常缓慢，需要数百年甚至更长时间。
在这个过程中，塑料会逐渐破碎成微小的颗粒，被称为“微塑料”。
这些微塑料体积很小，容易被海洋生物吞食，并沿着食物链传递。
微塑料不仅本身可能含有有毒物质，如增塑剂和阻燃剂，还会吸附海水中的其他污染物，如重金属和持久性有机污染物。
当海洋生物摄取了这些含有微塑料和污染物的食物后，毒素会在它们体内累积，对其健康产生严重影响。
长期积累下来，可能会导致生殖系统异常、免疫系统受损以及发育障碍等问题。
此外，塑料污染还会对海洋生态系统的结构和功能产生深远的影响。
它会破坏海洋栖息地，例如珊瑚礁。
塑料垃圾的堆积可能会覆盖珊瑚礁，影响其光合作用，阻碍其生长和繁殖。
海洋中的塑料还会改变海水的物理和化学性质，影响海洋的温度、盐度和酸碱度等，进而影响海洋生态系统的平衡。
塑料污染对海洋食物链的影响也是不可忽视的。
由于微塑料在海洋中的广泛存在，它们可能会进入浮游生物体内。

Effects on wildlife & fisheries
(how have the plastic debris affected them)
1. Entanglement •Entanglement is responsible for many different kinds of wildlife. Such as seals, fish, turtles, and birds. •These animals get caught in the debris and end up suffocating or drowning. •They don’t have hands like us to untangle themselves, as a
• Naval and research vessels eject waste and military equipment that are deemed unnecessary.
• Pleasure crafts release fishing gear and other types of waste, either accidentally or through negligent handling.
• The largest ocean-based source of plastic pollution is discarded
fishing gear (including traps and nets), estimated to be up to 90% of
plastic debris in some areas. （ Hammer, J; Kraak, MH;
How plastic waste is affecting wildlife and fisheries
The main waste in the ocean is the Plastic debris. About 80 percent of marine debris is plastic.
Every year, a huge number of seabirds, turtles, and fisheries died of

Human actions that polluted the pacific ocean
• Merchant ships expel cargo, sewage, used medical equipment, and other types of waste that contain plastic into the ocean.
• The North Pacific Gyre, for example, has collected the so-called
“Great Pacific Garbage Patch”, which is now estimated to be one to twenty times the size of Texas (approximately from 700,000 to 15,000,000 square kilometers). In samples taken in 1999, the mass of plastic exceeded that of zooplankton (the dominant animal life in the area) by a factor of six. (Weisman&Alan，2007). Click to see more details

Convincing data(on Pacific Ocean)
• In a 2008 Pacific Gyre voyage, Algalita Marine Research
Foundation researchers began finding that fish are eating plastic fragments and waste. Of the 672 fish caught during that voyage, 35% had ate plastic pieces. Click to see more details

Example: the seal is stuck by fishing nets
This picture tells us a sad story about this turtle: it was trapped accidentally when it was young. As it grew bigger and bigger, the rubber band limited it. As a result, its body was deformed.
