Contributions of Rhodolith Beds to People

As presented in the other chapters of the book, calcareous algae are of paramount importance in several ecosystemic aspects. In this chapter, we address the importance of assessing the value of this ecosystem in an integrated way that goes according to different perspectives and contexts around the world. The pluralist understanding and evaluation of the value of these ecosystems should lead policymakers to maintain their sustainability. Understanding, therefore, aspects of various rhodolith beds should help in understanding the importance of these ecosystems in providing contributions to people. Here, we briefly present the processes that occur within rhodolith beds that lead to the contributions of this ecosystem to people. These contributions are known within regulatory categories, such as oxygen production and carbon storage; materials, such as nutrient cycling and the food chain; in addition to nonmaterial contributions, such as scenic beauty landscapes that attract tourists; or even as inspiration for art and science.
