Introduction Excerpt: The world’s oceans are in trouble. Global warming is causing sea levels to rise and reducing the supply of food in the oceans. The ecological balance of the ocean has been disturbed by invasive species and cholera. Many pesticides and nutrients used in agriculture end up in the coastal waters, resulting in oxygen depletion that kills marine plants and shellfish. Meanwhile the supply of fish is declining due to overfishing. Yet to flourish, humankind requires healthy oceans; the oceans generate half of the oxygen we breathe, and, at any given moment, they contain more than 97% of the world’s water. Oceans provide at least a sixth of the animal protein people eat. Living oceans absorb carbon dioxide from the atmosphere and reduce climate change impacts. Many civil society groups (NGOs) are trying to protect this shared resource. As example, OceanMind uses satellite data and artificial intelligence (AI) to analyze the movements of vessels and compare their activities to historical patterns. The NGO can thus identify damaging behavior such as overfishing
