塑料袋不可生物降解。他们飞离垃圾堆,垃圾车和垃圾填埋场,然后堵塞雨水基础设施,漂浮在水道上,破坏景观。如果一切顺利,他们最终会进入适当的垃圾填埋场,在那里可能需要1000年或更长时间才能分解成更小的颗粒,继续污染土壤和水。塑料袋对鸟类和海洋哺乳动物也构成严重危漂浮的塑料袋经常欺骗海龟,认为它们是他们最喜欢的猎物之一,海蜇。每年吞下或窒息废弃的塑料袋后,成千上万的动物死亡。即使对于中东的骆驼来说,这个错误的身份问题显然也是一个问题!暴露在阳光下足够长的塑料袋会发生物理破坏。紫外线使塑料变脆,将其分解成更小的碎片。然后小碎片与土壤,湖泊沉积物混合,被溪流捡起,或最终导致大太平洋垃圾填埋场和其他海洋垃圾沉积物。最后,生产塑料袋,将它们运送到商店,并将旧的塑料袋运到垃圾填埋场和回收设施需要数百万加仑的石油,这是一种不可再生的资源,可以说更好地用于更有益的活动,如运输或加热。一些企业已停止向他们的客户提供塑料袋,许多社区正在考虑禁止使用塑料袋 – 旧金山是2007年第一家这样做的。一些州正在试验强制存款,购买费和彻底禁令等解决方案。各种杂货连锁店现在都有最小化使用的政策,包括向希望向他们提供塑料袋的客户收取少量费用。同时,您可以采取以下几种方法来帮助:切换到可重复使用的购物袋。由可再生材料制成的可重复使用的购物袋通过更换纸袋和塑料袋来节约资源。可重复使用的袋子很方便,有各种尺寸,款式和材料。不使用时,可将一些可重复使用的袋子卷起或折叠得足够小,以便放入口袋中。确保定期清洗它们。回收塑料袋。如果你不时地使用塑料袋,一定要回收它们。现在许多杂货店收集塑料袋进行回收。如果您没有,请查看您所在社区的回收计划,了解如何回收您所在地区的塑料袋。与大多数环境问题一样,塑料袋问题并不像看起来那么简单。塑料工业集团喜欢提醒我们,与纸袋替代方案相比,塑料袋重量轻,运输成本低,并且需要相对较少(不可再生)的资源来制造,同时产生较少的浪费。如果您的社区可以使用合适的设施,它们也是完全可回收的。他们对垃圾填埋场的贡献实际上相当小,根据业界的估计,65%的美国人实际上重新使用和重新使用他们的塑料袋。当然,当与可清洗,坚固的可重复使用的购物袋进行比较时,这些论点不那么令人信服。

新西兰怀卡托大学论文代写:塑料袋

Plastic bags are not biodegradable. They fly away from garbage dumps, garbage trucks and landfills, then block the rainwater infrastructure, float on the waterways and destroy the landscape. If all goes well, they will eventually enter the proper landfill, where it may take 1000 years or more to break down into smaller particles and continue to contaminate the soil and water. Plastic bags also pose serious dangers to birds and marine mammals. Plastic bags often deceive sea turtles and consider them to be one of their favorite prey, sea otters. Thousands of animals die after swallowing or suffocating discarded plastic bags every year. Even for the camels in the Middle East, this wrong identity problem is obviously a problem! Physical damage is caused by plastic bags that are exposed to sunlight long enough. Ultraviolet light makes plastics brittle and breaks them down into smaller pieces. Small debris is then mixed with soil, lake sediments, picked up by streams, or eventually led to large Pacific landfills and other marine debris deposits. Finally, the production of plastic bags, transporting them to stores, and transporting old plastic bags to landfills and recycling facilities requires millions of gallons of oil. This is a non-renewable resource that can be said to work better. For more beneficial activities such as transportation or heating. Some companies have stopped offering plastic bags to their customers, and many communities are considering banning the use of plastic bags – San Francisco was the first to do so in 2007. Some states are experimenting with solutions such as compulsory deposits, purchase fees and a total ban. Various grocery chains now have a policy of minimizing usage, including a small fee for customers who want to provide plastic bags to them. At the same time, there are several ways to help: switch to a reusable shopping bag. Reusable shopping bags made from renewable materials save resources by replacing paper and plastic bags. Reusable bags are handy in a variety of sizes, styles and materials. When not in use, some reusable bags can be rolled up or folded down enough to fit in a pocket. Make sure to clean them regularly. Recycle plastic bags. If you use plastic bags from time to time, be sure to recycle them. Many grocery stores now collect plastic bags for recycling. If you don’t have one, check out the recycling program in your community to find out how to recycle plastic bags in your area. As with most environmental issues, the plastic bag problem is not as simple as it seems. The Plastics Industry Group likes to remind us that plastic bags are lighter in weight, have lower shipping costs, and require relatively less (non-renewable) resources to produce, while producing less waste, compared to paper bag alternatives. If your community has access to the right facilities, they are also fully recyclable. Their contribution to landfills is actually quite small, and according to industry estimates, 65% of Americans actually reuse and reuse their plastic bags. Of course, these arguments are less convincing when compared to washable, sturdy, reusable shopping bags.
