Marine mammals suffer, and entire ecosystems are put at risk. [[Tuna and his friend Finley continuedly swimming forward]]Tuna and his friend Finley were enjoying their swim in the ocean when they spotted a fisherman on a boat nearby. Tuna couldn't help but feel concerned about the dangers of fishing gear to sea creatures like himself. Tuna asks Finley, "How does entanglement in fishing gear affect marine mammals?" Tuna thinks that it can... [[It can lead to suffocation and drowning]] [[It can help them catch more food easily]] Finley shares a heart-wrenching tale of a young seal named Sammy. "Fishing nets and lines can trap marine mammals, making it hard for us to breathe," explains Finley. He describes how entangled animals struggle to free themselves, but sadly, many cannot escape, leading to suffocation and drowning. <img src="https://images.pexels.com/photos/891118/pexels-photo-891118.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=2" width="50%"> [[Tuna gains a deeper understanding of how entanglement in fishing gear affects marine mammals.]]Tuna looks curious, and Finley chuckles at the idea. "While it might seem helpful, fishing gear is designed for humans, not marine mammals," says Finley. He clarifies that entanglement is dangerous and can hinder marine mammals' natural hunting abilities, leading to injuries and even death. <img src="https://images.pexels.com/photos/891118/pexels-photo-891118.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=2" width="50%"> [[Tuna gains a deeper understanding of how entanglement in fishing gear affects marine mammals.]] Finley's stories serve as cautionary tales, highlighting the need for responsible fishing practices and gear modifications to protect marine life. [[After bidding farewell to Finley, Tuna continues her exploration]] Tuna encounters a playful sea turtle named Tommy. <img src="https://images.pexels.com/photos/847393/pexels-photo-847393.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500" width="50%"> As they swim together, dark clouds gather, and a storm approaches, bringing heavy rain. Tommy notices Tuna's concern and asks, "Do you know what is ocean acidication?" Tuna answers, "Ocean acidification is a process where the pH level of seawater decreases." Tommy asks again, "But what causes ocean acidification?" [[Increased carbon dioxide (CO2) absorption by the ocean:]] [[Excessive rainfall and freshwater runoff]]Tuna recalls the lessons learned from her friends and explains to Tommy. "Humans release too much CO2 from burning fossil fuels, and the ocean absorbs it. This makes the water more acidic, harming marine life, especially creatures with shells and skeletons." <img src="https://images.pexels.com/photos/3641377/pexels-photo-3641377.jpeg?auto=compress&cs=tinysrgb&w=800" width="50%"> Tuna nods, "So the main reason of this environmental challenge is increasing carbon dioxide absorption, and it make the ocean more acidic" [[Tuna and Tommy continue their swim]] Tuna looks intrigued, wondering if the rain is related. Tommy gently clarifies, "Rain is essential, but excessive rainfall can cause runoff from land, carrying pollutants and chemicals to the ocean. However, ocean acidification primarily results from increased CO2 absorption." <img src="https://images.pexels.com/photos/12446378/pexels-photo-12446378.jpeg?auto=compress&cs=tinysrgb&w=800" width="50%"> Tuna nods, "So the main reason of this environmental challenge is increasing carbon dioxide absorption, and it make the ocean more acidic" [[Tuna and Tommy continue their swim]]As Tuna and Tommy discuss the environmental challenges, Tommy's curiosity leads to another question. "What is a major source of carbon dioxide (CO2) emissions contributing to climate change?" he asks. [[Deforestation and land-use changes]] [[ Volcanic eruptions]]Tuna shares stories of her friends, like Coral, who have experienced the impacts firsthand. "Acidic waters dissolve the shells of creatures like corals, clams, and sea snails," she explains. "Without strong shells, these marine organisms face difficulties surviving and are more vulnerable to predators." <img src="https://images.pexels.com/photos/320260/pexels-photo-320260.jpeg?auto=compress&cs=tinysrgb&w=800" width="50%"> During this journey, both Tuna and Tommy know more about ocean acidification. They discuss how deforestation and human land-use changes contribute to climate change by releasing CO2 into the atmosphere. It underscores the significance of human actions in climate change and the importance of adopting sustainable practices to mitigate its effects. [[Is her journey over?]]Tuna looks hopeful, imagining potential positive effects. Tommy gently shakes her head, clarifying, "Ocean acidification may not help marine organisms. Instead, it can disrupt their growth and reproductive cycles. For example, some planktonic species may struggle to build their protective shells, affecting their survival and disrupting the food chain." During this journey, both Tuna and Tommy know more about ocean acidification. They discuss how deforestation and human land-use changes contribute to climate change by releasing CO2 into the atmosphere. It underscores the significance of human actions in climate change and the importance of adopting sustainable practices to mitigate its effects. [[Is her journey over?]]Tuna explains how human activities like cutting down forests for agriculture and urbanization release large amounts of CO2 into the atmosphere. "When trees are removed, they can no longer absorb CO2, contributing to the greenhouse effect and climate change," she says. <img src="https://images.pexels.com/photos/1268076/pexels-photo-1268076.jpeg?auto=compress&cs=tinysrgb&w=800" width="50%"> "So human activities are the major source of CO2 emissions.", Tommy says. [[Tuna and Tommy continue swiming]]Tommy wonders if volcanoes play a significant role. Tuna smiles and replies, "While volcanic eruptions release CO2, their impact is relatively small compared to human activities. It's essential to focus on reducing our carbon footprint to tackle climate change effectively." "So human activities are the major source of CO2 emissions.", Tommy says. [[Tuna and Tommy continue swiming]]Tuna and Tommy continue their swim, then Tommy asks, "How does ocean acidification affect marine organisms?" Tuna thinks and try to answer this question: [[Maybe It can weaken the shells and skeletons of marine creatures]] [[Maybe It enhances their growth and reproductive abilities]]
