What things do you need to survive on an island?

To survive on an island, you need access to fresh water, food sources (like fruits, fish, or edible plants), and shelter for protection from the elements. Basic tools for gathering resources, such as a sharp object for cutting and a means to start a fire, are also essential. Additionally, navigation tools or a signal for rescue can be crucial for eventual escape. Lastly, maintaining a positive mindset and the will to survive is vital for overcoming challenges.
