“…Many near-shore, coastal systems contain submerged aquatic vegetation, such as seagrass beds or kelp forests, that are increasingly mentioned as a solution to address ocean acidification (21, 179). Submerged aquatic vegetation's ability to create habitat and slow water flow in coastal regions is better established (180)(181)(182) than its ability to consistently capture and sequester CO 2 or modulate local pH swings, where evidence is mixed (183)(184)(185). Nevertheless, restoring and preserving submerged aquatic vegetation is increasingly seen as a widely useful marine conservation step that will help sustain marine provisioning and regulating services (186) and may help mitigate ocean acidification in localized areas (21).…”

Rising atmospheric carbon dioxide (CO2) levels, from fossil fuel combustion and deforestation, along with agriculture and land-use practices are causing wholesale increases in seawater CO2 and inorganic carbon levels; reductions in pH; and alterations in acid-base chemistry of estuarine, coastal, and surface open-ocean waters. On the basis of laboratory experiments and field studies of naturally elevated CO2 marine environments, widespread biological impacts of human-driven ocean acidification have been posited, ranging from changes in organism physiology and population dynamics to altered communities and ecosystems. Acidification, in conjunction with other climate change–related environmental stresses, particularly under future climate change and further elevated atmospheric CO2 levels, potentially puts at risk many of the valuable ecosystem services that the ocean provides to society, such as fisheries, aquaculture, and shoreline protection. This review emphasizes both current scientific understanding and knowledge gaps, highlighting directions for future research and recognizing the information needs of policymakers and stakeholders. Expected final online publication date for the Annual Review of Environment and Resources, Volume 45 is October 19, 2020.

“…Macroalgae have cell types that are similar to those of terrestrial vascular plants. Furthermore, the macroalgae may be either marine or freshwater [47,78]. Macroalgae can accumulate heavy metals, synthetic dyes, and other contaminants reaching concentrations that are thousands of times higher than the corresponding concentrations in seawater.…”

Rapid industrialization leads to serious environmental hazards due to the increase in the release of pollutants into the environment. Industries that use synthetic dyes for different applications are a predominant source for dye contaminants by releasing the dye in wastewater with pretreatment or without treatment directly into the water bodies, making serious water pollution in the environment. Therefore, it is imperative to safeguard the environment from such contaminants and their associated negative impacts. The conventional treatment method that is used to treat dye-contaminated wastewater is generally costly and has a possibility to produce secondary metabolites. Due to the above problems, the biological method is preferable to treat effluent or dye-contaminated wastewater. Phycoremediation is an algae-based eco-friendly dye abatement technique from contaminated environments. This review highlights the phycoremediation of dyes and its underlying mechanisms along with the information on synthetic dyes, classification, hazardous effects, and other major techniques of dye abatement. This review provides a comprehensive insight into several influencing factors such as pH, temperature, contact time, the dose of algae biomass, and agitation speed, as well as functional groups involved in the phycoremediation process.

“…Similarly, macroalgal forests provide a range of ecosystem services (Vásquez et al, 2014;Bennett et al, 2016;Macreadie et al, 2017;Blamey and Bolton, 2018), including direct support of commercial, recreational, and subsistence fisheries and aquaculture. Indirect ecosystem services include erosion control, climate change mitigation and adaptation, and biogeochemical cycling of nitrogen, carbon, and phosphorus.…”

“…The contribution of macroalgae to carbon sequestration varies among species (Trevathan-Tackett et al, 2015), but more direct estimates are needed to quantify sequestration, and this requires a paradigm shift in accounting procedures as well as development of methods to trace carbon from donor to sink habitats in the ocean (Krause-Jensen et al, 2018). As vegetated ecosystems have declined substantially in area (Waycott et al, 2009), many coastal areas have been converted from carbon sinks to sources, a shift that can, in principle, be reversed (Pendleton et al, 2012;Macreadie et al, 2015Macreadie et al, , 2017Marbà et al, 2015;Kerrylee et al, 2018). One approach to quantifying the processes that mediate carbon storage and release from seagrass sediments is the TeaComposition H 2 O project, which uses widely available tea bags to measure organic carbon preservation in seagrass and other wetland sediments, currently under way across 350 nearshore marine sites.…”

“…Growing understanding of the valuable services provided by seagrass and macroalgal stands has strengthened interest in conserving them. Originally, these concerns were based primarily on contributions of coastal vegetated ecosystems to commercial fisheries but have expanded to include their importance to biodiversity and threatened species, artisanal fisheries (Nordlund et al, 2018), good water quality, resilience against climate change, and cultural significance (Macreadie et al, 2017;.…”
