My Ocean Twin aims to tackle the colossal problem of ocean plastic waste. Through the creation of a digital twin of the ocean, My Ocean Twin offers a unique solution that can help save our oceans from pollution. A sophisticated grid system has been implemented, which enables the virtual partitioning of the ocean into geolocated plots. These plots are minted as non-fungible tokens (NFTs), which can be purchased, sold, and traded. The revenue generated from these transactions will be channeled towards a selection of Non-Governmental Organizations (NGOs) that specialize in cleaning up the ocean plastic waste. With My Ocean Twin, every individual can contribute to the preservation of our oceans and the conservation of marine life.
