Under the influence of alien invasive species, the ecosystem has changed, and so has the natural balance, genetic diversity, and richness of the original resident species and resources. These factors can also support local economies through hunting and aquaculture, and are also affected by climate change. Similarly, some coastal areas that rely heavily on ecotourism have lost revenue due to pollution, as tourists are no longer willing to visit their beaches or shores. The World Trade Association also points out that the negative effects of low biodegradation rates are generally felt in poor countries that cannot afford to pay for clean-up. The positive feedback loop of biodegradable materials, in turn, makes it difficult to effectively control its own pollution sources.

Enzymatichydrolysis is the main form of biological decomposition, resulting from the destruction of the chemical bonds in organic molecules (including some organic polymers) by microbial enzymes. Warm, humid climates favor microbial enzymes that degrade natural or artificial polymers.
