The aim of this review was to present the main anthropogenic threats to seabirds, a taxonomic group described as environmental sentinels, and the dynamics between parasites and hosts and their relationship with the health of the marine ecosystem. Coastal marine environments support various anthropogenic activities, exposing seabirds to multiple and synergistic environmental changes. These activities are considered negative to the maintenance of several seabird species, such as exposure to constant aquatic contaminants and fishing. In addition, parasitic and infectious diseases (viral, bacterial, and fungal) may also play an important role in maintaining some seabird populations. Some pathogenic organisms have public health importance and/or may indicate environmental quality. Host-parasite interaction may be positive, negative, or absent depending on some environmental factors potentially associated with degradation, as well as intrinsic factors of host or parasite. In addition, investigating aspects of seabird mortality also contributes to the constant population monitoring and understanding of the interaction between animals, humans, and the environment. Thus, seabirds and their parasitofauna can provide important ecological and health information, including those related to environmental health, supporting strategies for reducing degradation and maintaining marine ecosystems.
