Many adaptation options exist for natural ecosystems and managed systems, including coastal areas and human health. Such approaches address the risk of sea level rise, coastal devastation, and loss of livelihoods. These solutions are necessary and practical, but they must be implemented in a way that will protect people and the environment. They must also include measures to improve human health and livelihoods. In addition, there are other considerations that must be taken into account, such as the long-term cost of adaptation.
