About the Book

This book is for the typical Scala developer, probably with a Java background, who is both sceptical and curious about the Functional Programming (FP) paradigm. This book justifies every concept with practical examples, including writing a web application.

Supporting Indigenous Peoples. Protecting the Amazon.

http://amazonwatch.org
Amazon Watch is a nonprofit organization founded in 1996 to protect the rainforest and advance the rights of indigenous peoples in the Amazon Basin. We partner with indigenous and environmental organizations in campaigns for human rights, corporate accountability and the preservation of the Amazon's ecological systems.
We envision a world that honors and values cultural and biological diversity and the critical contribution of tropical rainforests to our planet's life support system. We believe that indigenous self-determination is paramount, and see that indigenous knowledge, cultures and traditional practices contribute greatly to sustainable and equitable stewardship of the Earth. We strive for a world in which governments, corporations and civil society respect the collective rights of indigenous peoples to free, prior and informed consent over any activity affecting their territories and resources. We commit, in the spirit of partnership and mutual respect, to support our indigenous allies in their efforts to protect life, land, and culture in accordance with their aspirations and needs.
