OneTree(s) is a public experiment that generates (material, scientific and cultural) evidence and public spectacles on issues of environmental and political concern. In the case of OneTrees, global warming, air quality, and genetically modified organisms (gmos) are currently being addressed. Other issues and parameters are in development.

Other public experiments include: the Feral Robotic Dogs project: upgraded commercially robotic dog toys that have been transformed into activist instruments to find and display urban pollutants; the OOZ: a series of technological interfaces to facilitate interaction between human and nonhumans in urban environments; HowstuffisMade: a collectively produced encyclopedia documenting manufacturing processes and labor conditions.

Each of these projects places evidence in the public sphere, that would otherwise only be available to particular experts, as a strategy to change the structure of participation between lay expert participants. In other words, by widening access to material evidence, we may widen the political engagement.

Additionally the OneTrees project can be contrasted to mainstream representations of global environmental issues. The popular press introduces these into the public imagination as scientific discoveries and facts, with no access to the material evidence on which the truth claims are based. This promotes the passive consumption of ‘facts’ vs the active interpretation, even contestation that we can see in the OneTrees ‘faqs’. Below, is a selection of FAQs that viewers have addressed to the OneTrees project, demonstrating some of the complex questions that the public viewers pose, and engage.
