A cоаstаl regiоn is experiencing rаpid biоdiversity loss due to rising sea levels and increasing temperatures associated with climate change. Native plant species are declining, which is disrupting food sources for local animal populations and leading to further ecosystem instability. Task:Propose a realistic, evidence-based strategy to help preserve biodiversity in this region. Your answer should: Identify the main biological challenges caused by climate change in this scenario. Propose one primary solution (e.g., conservation strategy, restoration effort, policy, or technological intervention). Explain how your solution would mitigate the impact on biodiversity. Discuss at least one potential limitation or trade-off of your approach. Justify why your solution is more effective than any other approach.
