a look into the book: BiodiversityLeseprobe



Biodiversity is everything. It is our home and life-support system. It is normal that such a complex concept will be approached in such diverse, sometimes even contradicting ways. Biodiversity is and will remain a major topic for humankind in the quest for a better world. Understanding biodiversity eventually means knowing and treasuring our home.
