Estuaries are transitional areas between land and sea that experience both freshwater and saltwater. They face threats from natural disturbances like winds and tides as well as human impacts such as pollution, development, and invasive species. Estuaries provide environmental services by filtering sediments and pollutants from upland waters. They also act as protective buffers against floods and storms. Additionally, estuaries are critical habitats that support thousands of species and have economic value through activities like tourism, fishing, and transportation.

Estuaries
Estuaries are partially enclosed coastal bodies of water where freshwater from rivers and streams mixes with saltwater from the ocean. They are highly productive environments that support many species of plants and animals adapted to the transition between fresh and salt water. Estuaries come in four types depending on their formation: coastal plain, tectonic, bar-built, and fjords. They provide important ecological, economic, and environmental benefits but are threatened by increasing development and pollution from coastal populations.

Wetlands
Wetlands are areas where water covers the soil or is present near the surface for all or part of the year, providing habitat for wildlife and plants. They filter and store water, absorb flood waters and winds, and offer recreational activities. Wetlands are classified as marine, estuarine, lacustrine, riverine, or palustrine, and examples of each type found in Trinidad and Tobago include the Bon Accord lagoon, Caroni swamp, Godineau river, and Buccoo Bay freshwater marsh.
Wetland
+A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.

Marine and coastal ecosystems
Marine and coastal ecosystems are diverse and complex systems. The marine ecosystem is the largest ecosystem on Earth, covering over 70% of the planet's surface. It contains a variety of habitat types, from coral reefs and kelp forests to deep sea and open ocean environments. Coastal ecosystems like mangroves, sandy shores, and estuaries exist at the interface between land and sea. These ecosystems support a high level of biodiversity but are threatened by rising sea levels and ocean acidification due to climate change. Careful management is needed to protect these important ecosystems.
Marine ecosystem
The document summarizes several marine ecosystems. It describes how oceans cover 70% of the Earth's surface and include shorelines like tidal flats and mangrove forests. Specific ecosystems are found around the world, depending on climate and geography. These include coral reefs, estuaries, salt marshes, mangrove forests, and the deep sea. Salt marshes are coastal wetlands flooded by tides that are dominated by salt-tolerant grasses. The intertidal zone is the shore area above and below the water line during tides, containing habitats for starfish and coral. Mangroves are salt-tolerant trees adapted to harsh coastal conditions.

The document highlights the ecological importance of each in areas like biodiversity, climate regulation, and provision of resources. Sacred groves are also introduced as forest areas of religious significance.
Coast
Coastal landforms such as beaches, bays, capes, and peninsulas are shaped by the erosion and deposition of sediments from waves and tides. Coastal environments support a wide variety of plant and animal life, including mangrove forests, coral reefs, and migratory bird populations. Human activities like fishing, trade, tourism and urban development have drawn large populations to coastal areas but have also threatened coastal ecosystems through pollution, climate change, and overexploitation of resources. Coastal regions face risks from natural hazards exacerbated by sea level rise.
WETLANDS.pptx
Wetlands provide important hydrologic, water quality, habitat, and direct use values. They help store floodwaters, stabilize shorelines, filter pollutants from surface runoff, transform nutrients, and provide wildlife habitat. However, over half of the world's wetlands have been lost since 1900 due to conversion for development, drainage, mining, pollution from agriculture and industry, and dam construction. Wetlands are increasingly recognized for their values but continued to face major threats.

Mangrove & It,s threats
Mangroves are salt-tolerant plants found in tropical and sub-tropical coastlines that provide important environmental and socioeconomic benefits. They act as coastal buffers against storms and erosion. However, mangroves in Sri Lanka are threatened by pollution, development, and harvesting. Protecting mangroves requires limiting coastal development and runoff, reforestation efforts, and community education about their importance to ecosystems and livelihoods.
Chapter 7 Section 2.ppt
Coastal wetlands like estuaries, salt marshes, and mangrove swamps provide important habitat for many marine plants and animals. However, they are threatened by human pollution from sewage, industrial waste, and agricultural runoff. Estuaries in particular cannot cope with excessive human pollution levels. [/SUMMARY]
Aquatic ecosystem and water pollution
Aquatic ecosystems can be freshwater like lakes, rivers, and wetlands, or marine water like oceans. They contain a variety of organisms adapted to different zones based on factors like sunlight, temperature, and oxygen levels. Aquatic ecosystems are important for biodiversity, breeding grounds, and being part of the water cycle, but are threatened by pollution, nutrient runoff, and other human impacts that can cause eutrophication and loss of species. Proper management of fertilizers, waste, and industrial discharges is needed to protect these fragile environments.
Estuaries
Estuaries are transitional zones where rivers meet the sea. They are characterized by varying salinity levels due to mixing of fresh and salt water. Estuaries contain diverse habitats and are among the most productive ecosystems. They provide many resources including fisheries, tourism, transportation and cultural values. However, estuaries face threats such as land reclamation, pollution, overfishing and natural hazards. Protecting these fragile ecosystems and their services is important for both environmental and economic reasons.
Estuaries1
Estuaries are semi-enclosed bodies of water where freshwater from rivers meets and mixes with saltwater from the ocean. They represent a close interaction between land and sea and are among the most productive environments on Earth. Estuaries contain distinct communities that are adapted to the mixing of fresh and salt water and the tidal fluctuations, including open water, mudflats, salt marshes, and mangrove forests. Organisms in the intertidal zone between high and low tide lines have adaptations to withstand periods of wetness and dryness from the tides.
Croatan sound
North Carolina's Outer Banks is home to many beautiful estuaries. Estuaries are coastal areas with shallow waters that are mixed with sea water and freshwater flowing from watersheds. These areas are known as nurseries for thousands of species of sea creatures. Sea turtles come ashore to lay their eggs and when those hatch, the baby turtles scramble back toward the ocean where they will live out their lives. Fish, manatee, sharks, starfish, and many other species are at home in the Croatan Sound Estuary.
Floating Wetlands
Louisiana contains many marshes and wetlands that constitute about 40% of the state's landscape, providing important habitat for wildlife. However, Louisiana has experienced a significant amount of wetland loss over recent decades, with around 80% of national wetland loss occurring in the state. Specifically, Louisiana wetlands have declined by 30% just in the past 10 years, which is problematic as the lost wetlands are often converted to open water rather than being restored.
coastal wetland and its thereats
Wetlands provide important ecosystem services but face many threats. On-site threats include draining wetlands for agriculture, dumping waste, and pollution from nearby activities. Off-site threats involve upstream deforestation, dams altering water flows, and pollution from distant sources. A key threat is conversion to aquaculture through draining or filling wetlands. Wetlands are drained and filled to make way for shrimp or fish farms, eliminating natural habitat.

Exploring the Fascinating World of the Green Sea Ecology, Biodiversity, and C...
The Green Sea is a vast and complex ecosystem that is home to a diverse array of marine species, including fish, crustaceans, mammals, and birds. It is a critical component of the world's oceans and plays a vital role in maintaining the health and well-being of the planet's biodiversity. However, the Green Sea faces numerous threats, including overfishing, habitat destruction, pollution, climate change, and invasive species.
The biodiversity of the Green Sea is one of its most important features. It includes a variety of habitats, such as coral reefs, seagrass beds, and estuaries, which provide essential breeding, feeding, and sheltering grounds for numerous species. Coral reefs are particularly important as they support a high level of biodiversity and provide essential ecosystem services, such as carbon sequestration and shoreline protection. Unfortunately, coral reefs are under threat due to a variety of factors, including warming oceans, acidification, pollution, and destructive fishing practices.
Seagrass beds are also critical habitats in the Green Sea, providing food and shelter for a variety of species, including sea turtles, fish, and crustaceans. Seagrass beds also play a vital role in nutrient cycling and carbon sequestration, making them important for the overall health of the marine ecosystem. However, seagrass beds are also under threat, primarily from coastal development and pollution.
Estuaries are another important habitat in the Green Sea, serving as critical nurseries for many fish and shellfish species. They are also essential for nutrient cycling and water filtration, making them vital for maintaining the overall health of the ecosystem. Unfortunately, estuaries are under threat from a variety of human activities, including pollution, dredging, and land reclamation.
In addition to habitat destruction, overfishing is a significant threat to the biodiversity of the Green Sea. Many species in the Green Sea are already overexploited, and some are on the brink of extinction. Overfishing can have significant ecological impacts, disrupting food webs and altering the overall structure of the ecosystem.
Pollution is also a major threat to the biodiversity of the Green Sea. Chemical runoff from agriculture, oil spills, and plastic waste all have detrimental effects on marine life. Plastic waste is particularly problematic, as it can persist in the environment for hundreds of years, harming wildlife through ingestion or entanglement.
Climate change is another significant threat to the biodiversity of the Green Sea. Rising temperatures and ocean acidification can have a range of impacts on marine life, including changes in distribution, behavior, and growth rates. Climate change can also lead to more frequent and severe storms, which can damage marine habitats and disrupt ecosystems.
Finally, invasive species can also pose a threat to the biodiversity of the Green Sea. Invasive species are non-native species that are introduced to

Session Two: 'Expanding Pathways to Publishing Careers,' was held June 13, 2024.THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

estuary.pptx
- 2. Estuaries • transitional areas between the land and the sea, and between freshwater and saltwater environments
- 3. Threats to esturies • Natural disturbances include winds, tidal currents, waves, and ice. Anthropogenic disturbances include pollution, coastal development, and the introduction of non-native species to an area.
- 4. Benefits of esturies • Estuaries Perform Environmental Services Estuaries also perform other valuable services. Water draining from uplands carries sediments, nutrients and other pollutants to estuaries. As the water flows through wetlands such as swamps and salt marshes, much of the sediments and pollutants are filtered out. This filtration process creates cleaner and clearer water, which benefits both people and marine life.
- 5. • Estuaries Act as Protective Buffers Wetland plants and soils also act as natural buffers between the land and ocean, absorbing flood waters and dissipating storm surges. This protects upland habitat as well as valuable real estate from storm and flood damage.
- 6. • Estuaries Are Critical Natural Habitats Thousands of species of birds, mammals, fish and other wildlife depend on estuarine habitats as places to live, feed and reproduce. And many marine organisms, including most commercially-important species of fish, depend on estuaries at some point during their development.
- 7. • Estuaries Have Economic Value Estuaries have important commercial value and their resources provide economic benefits for tourism, fisheries and recreational activities. The protected coastal waters of estuaries also support important public infrastructure, serving as harbors and ports vital for shipping and transportation.
