A large amount of plastic waste has been discharged into the environment worldwide, which causes the current white pollution problem. The accumulated waste plastics in the environment can be furtherly degraded into small pieces such microplastics and nanoplastics through weathering, which will do more harm to the environment and humans than large plastics. Therefore, plastic production and disposal are needed to be considered. Biodegradable plastics (BPs) have become the focus of recent research due to their potential biodegradability and harmlessness, which would be the most effective approach to manage the issue of plastic waste environmental accumulation. However, in the long run, it is uncertain whether BPs can be a promising solution to waste disposal and global plastic pollution. Consequently, both sides of the dispute are discussed in this paper. At present, most conventional plastics can not be replaced by theses BPs. Biodegradation of BPs needs certain environmental conditions, which are not always reliable in the environment. Additionally, changes in human behavioral awareness will also affect the development and application of BPs. BPs should not be considered as a technical solution, thus excusing our environmental responsibility, because littering does not change with the promotion of an effective technology. As such, the conclusion is that BPs may be a part of the solution. The effectiveness in providing environmentally solutions for plastic waste management depends on the combination of affordable waste classification technologies and investment in organic waste treatment facilities. Therefore, there is still a long way to go to solve the global plastic pollution through BPs.

可降解塑料是否是解决全球塑料污染的有前途的解决方案？
全世界有大量的塑料废物被排放到环境中，这导致了当前的白色污染问题。环境中累积的废塑料可以通过风化进一步降解为小块，例如微塑料和纳米塑料，这比大塑料对环境和人类的危害更大。因此，需要考虑塑料的生产和处置。可生物降解塑料（BPs）由于其潜在的可生物降解性和无害性而成为近期研究的重点，这将是处理塑料废物环境累积问题的最有效方法。但是，从长远来看，尚不确定BP能否成为废物处理和全球塑料污染的有前途的解决方案。所以，本文讨论了双方的争端。目前，大多数常规塑料无法用这些BP代替。BP的生物降解需要一定的环境条件，这些条件在环境中并不总是可靠的。此外，人类行为意识的变化也将影响BP的开发和应用。BP不应被视为一种技术解决方案，因此可以免除我们对环境的责任，因为乱扔垃圾不会随着有效技术的发展而改变。因此，结论是BP可能是解决方案的一部分。为塑料废物管理提供环境解决方案的有效性取决于可负担得起的废物分类技术和对有机废物处理设施的投资。因此，
