Managing Global Freshwater Biodiversity Crisis; Protection, Restoration and Conservation Strategies
AI summary Read the abstract
This chapter reviewed strategies for managing the global freshwater biodiversity crisis, examining threats including pollution, climate change, invasive species, and micro- and nanoplastic contamination. The authors discussed conservation strategies such as environmental DNA monitoring, habitat restoration, and improved water quality management to protect freshwater ecosystems that support approximately 10% of all known species.
Despite having a small surface area, freshwater ecosystems support about 10% of all species, making them essential to global biodiversity.These ecosystems support vital resources value more than $4 trillion a year, including food, drinking water, and employment opportunities.However, freshwater biodiversity has significantly decreased as a result of human activity such as pollution, climate change, invasive species introduction, and habitat degradation.The main threats to these ecosystems are discussed in this chapter, including freshwater salinization, harmful algal blooms, pollution, micro-plastic and nano-plastic, engineered nanomaterials and calcium declines.To protect biodiversity found in freshwater habitats, we discuss about the significance of conservation strategies like environmental DNA monitoring, improving water quality, restoring important habitats, and increasing public awareness.Given the continuous environmental pressures, it is stressed that combined policies and laws are necessary to guarantee the sustainable management and preservation of the ecosystem.
