In this project, Natasja investigates the loss of biodiversity in the urban environment with the help of an urban ecologist, biologist and bird expert. The Totems of Life form are going to create a unified habitat for urban endangered species such as sparrows, starlings and insects like wild bees and bumblebees. Central to the research and work is that the totems make a diverse contribution to urban life. The research and development is part of the Radical City inc. programme.

The totem has multiple symbolic meanings that refer to family clans and the supernatural, such as legends and stories about animals and mythical creatures. The Totems of Life are an ode to the flora and fauna of Amsterdam by placing them symbolically and practically on a higher pedestal.

The goal is to develop a new sculptural work that, layered in heights, accommodates various endangered urban animals. The work is going to be a spatial and visual statement that thus will actively contribute to the urban biotope. The form of the Totems of Life derive partly from the needs of urban animals and partly from Alers' recognizable, organic style.
