Human impacts on marine ecosystems

Human activities affect marine ecosystems as a result of pollution, overfishing, the introduction of invasive species,and acidification, which all impact on the marine food web and may lead to largely unknown consequences for the biodiversity and survival of marine life forms.

Glass sponges (Hexactinellida) are mainly found in the deep sea. The glass sponge Vazella pourtalesi (colloquially "Russian hat") is found in large quantities on the continental shelf off Canada: Photo: Ellen Kenchington, DFO. The Aquatic Symbiosis project will be the first to produce genomes of glass sponges. Its microbial symbionts, on the other hand, are already well researched (Bayer, Busch et al., mSystems 2020).
