Explain the SPI Resin Identification Coding System
SPI Resin Identification Coding System is a set of numbers used to identify the type of plastic which mostly used as the reference by the recyclers (Gendell, 2017). The code runs from 1-7 and identify the amount of resin in the plastic item.
解释SPI树脂识别编码系统 Plastic代写
译文：SPI树脂识别编码系统是一组用于识别塑料类型的数字，这些数字通常被回收商用作参考（Gendell，2017年）。该代码从1-7开始，用于识别塑料物品中的树脂量。
Types of Plastics
| Name | SPI Code | General Description | Uses |
| PET | 1 | Most commonly used. It is recyclable | Used to make plastic bottles and containers |
| HDPE | 2 | Most commonly recycled because it is low density. It has a low carbon footprint. | Used to make plastic pipes in storm sewers, drains, and culverts. |
| PVC | 3 | Less recycled. Most harmful to the environment. Toxic | Pipping, tubing, wire cable insulation, widescreen components. |
| LDPE | 4 | Less mass than HDPE. It is separated for recycling. | It is used to make household packaging and containers. |
| PP | 5 | Made from a combination of propylene monomers | Industrial applications in plastic parts in automobiles and device hinges. |
| PS | 6 | It is lightweight and easy to form and breaks easily. | It is mostly used to make it easy to discard parts like car parts including instrument panels, trim, knobs and more. |
| EPS | 7 | Not recyclable and should be avoided as they are not easy to break. | It is used to make fish boxes, packaging materials and insulation for panels for buildings. |
Discuss the Three Marine Zones
Surface Zones: The zone that is infiltrated by the sunlight and is less deep to about 200 meters. The temperatures vary with sunlight through convection heat.
Pelagic Zones: Part of the open sea that comprise of water column beside the near the coast and seafloor.
Benthic Zones: Is an ecological zone located at the bottom of the ocean, sea, or lake.
讨论三个海洋区 Plastic代写
译文：表面区域：被阳光渗透的区域，其深度不深至200米左右。 温度通过对流热随日光的变化而变化。
浮游带：公海的一部分，由靠近海岸和海底的水柱组成。
底栖区域：是位于海洋，海洋或湖泊底部的生态区域。
Explain How Trash Ends Up in Ocean Directly or Indirectly
The most common source of plastic trash comes from land activities. The garbage come from trash cans, streets, and landfills and are carried into sewers, rivers or directly dumped into the ocean. As such, below are various land activities that lead to pollution.
i.People litter
ii.Wind can blow the garbage from dumpsites or bins
iii.Storm drains
iv.Plastics runs from sewer pipes into waterways and then to the ocean
v.Sun radiation break down plastics to micro-plastics.
说明垃圾如何直接或间接地进入海洋 Plastic代写
译文：塑料垃圾的最常见来源来自陆地活动。 垃圾来自垃圾桶，街道和垃圾填埋场，被带入下水道，河流或直接倾倒入海洋。 因此，以下是各种导致污染的土地活动。
i.人乱扔垃圾
ii.风可以吹走垃圾场或垃圾箱中的垃圾
iii.雨水渠
iv.塑料从下水道进入水道，然后再到海洋
v.太阳辐射将塑料分解为微塑料。
Ways Animals Are Harmed by Plastics Found in Each of the Marine Zones
| One dimensional objects | Two-dimensional objects | Reticulated | Hollow bodied | Small Particles | Angular | |
| Surface Zone | Entanglement | Obstruction | Entanglement/suffocation | Ingestion | Ingestion | Laceration |
| Pelagic zone | Entanglement | Suffocation | Entanglement | Ingestion | Ingestion | Laceration |
| Benthic zone | Entanglement/ingestion | Suffocation | Entanglement | Laceration | Ingestion | Obstruction |
Based on Research, Describe the Estimated Number of Animals Harmed/Injured or Killed by Plastics
Plastic pollution in the ocean affects more than 700 species of aquatic animals (One Green Planet, 2019). There are more than 100 million animals die each year.
根据研究，描述估计被塑料伤害/伤害或杀死的动物的数量 Plastic代写
译文：海洋中的塑料污染影响700多种水生动物（一个绿色星球，2019年）。 每年有超过一亿的动物死亡。
Why Mismanaged Plastic Waste Tends to Be Higher in Areas that are Developing
Developing countries fail to have a mechanism for the proper disposal of plastics compared to developed countries. The countries also lack laws and regulations that minimize the use and management of plastic items.
为什么塑料垃圾管理不善在发展中地区的比例更高
译文：与发达国家相比，发展中国家没有适当处置塑料的机制。 这些国家也缺乏将塑料物品的使用和管理减至最少的法律和法规。
Three Examples of Large Efforts to Combat the Plastic Problem on the Planet Earth
Most countries are taking steps to ban the use of plastic items bags and bottles. China banned the importation of recycled plastic. Also, studies are underway to adopt the use of bioplastics which are easily broken down in dumpsites. Besides, countries like the U.S. are taking up the efforts of cleaning up the ocean in the bit to eliminate plastic litters.
努力抗击地球上塑性问题的三个例子 Plastic代写
译文：大多数国家都在采取措施禁止使用塑料物品的袋子和瓶子。 中国禁止进口再生塑料。 另外，正在进行研究以采用容易在垃圾场中分解的生物塑料。 此外，像美国这样的国家也正在努力清理钻头中的海洋，以消除塑料垃圾。
How One Can Prevent Plastic Pollution
Using other option of packaging like paper
Recycling plastics or reusing them
Disposing plastics in dumpsites where they can be burned safely
Participate in plastic cleaning programs
Sensitization of others about the harmful effects of plastics on the environment particularly marine life
如何预防塑料污染 Plastic代写
译文：使用其他包装方式，例如纸张
回收塑料或再利用它们
将塑料丢弃在可以安全燃烧的垃圾场
参加塑料清洁计划
让其他人对塑料对环境（尤其是海洋生物）的有害影响敏感
