There is an urgent need for new methods to regenerate damaged coastal ecosystems to maintain the shore protection, fisheries, tourism, and biodiversity services they provide. In the face of accelerating global warming, global sea level rise, and pollution the old ways of restoring these ecosystems have proven to be expensive failures, when conventional coral fragment farms are catastrophically wiped out by bleaching, diseases, and hurricanes, and mangroves and seagrasses laboriously transplanted are washed away by increasingly strong storm waves before their roots can grow. As these stresses increase, future long term success in regenerating these crucial ecosystems can only come with regenerative methods that greatly increase the settlement, growth, survival, and resistance to extreme environmental stresses from high temperature, mud, pollution, and waves. Biorock is the only method that does all these, not just for corals but for all marine animals and plants. Biorock reefs keep entire ecosystems alive during extreme stresses that would kill them, and regenerate entire ecosystems even in severely polluted areas where there has been no natural recovery. Around 500 Biorock Coral Arks built by Biorock Indonesia teams in Bali, Lombok, Flores, Sulawesi, Java, Sumbawa, and Ambon are growing about half of all the coral species in the world, and dramatically increasing the marine biodiversity around them.
