An "ark" is a large, often boat-like structure designed to hold and protect living beings or valuable items. The most famous ark in history is the Ark of the Covenant, which, according to religious texts, contained sacred objects and was a symbol of God's presence. Another well-known ark is Noah's Ark, described in the Bible as a vessel built by Noah to save his family and pairs of every animal species from a great flood. In modern contexts, the term "ark" can also refer to various conservation efforts, such as the Ark Project, which aims to preserve endangered species and their habitats. These initiatives often involve creating safe environments where animals can thrive and reproduce, ensuring their survival for future generations.
