Environmental Impact & Conservation - Sea turtles play a vital role in maintaining healthy seagrass beds and coral reefs within the ocean ecosystem [2] - Coastal development, including infrastructure like hotels and houses near beaches, disturbs sea turtle nesting processes [3] - Climate change, exemplified by the construction of sea walls, can impede turtles from reaching nesting beaches [4] - Pollution, specifically plastic mistaken for jellyfish and chemical runoff, poses a significant threat to sea turtles [5] - A disease causing tumors impacts sea turtles' ability to swim, see, and eat, affecting populations globally [5] - Conservation efforts, such as protecting nests, reducing plastic usage, and supporting conservation groups, are crucial for sea turtle survival [6] Population Trends & Challenges - Sea turtle populations are declining rapidly due to pollution, poaching, coastal development, and climate change [6] - Data collection on sea turtle populations was limited between 2020 and 2022 due to the COVID-19 pandemic [3] - Sea turtles require specific nesting environments: soft sandy beaches, warm temperatures, low light, and clean surroundings [4] - Despite challenges, Pinang remains an important nesting site for sea turtles, highlighting the need for continued conservation efforts [2][6]
