Book Description
The violence wrought by climate change, toxic drift, deforestation, oil spills, and the environmental aftermath of war takes place gradually and often invisibly. Using the innovative concept of "slow violence" to describe these threats, Rob Nixon focuses on the inattention we have paid to the attritional lethality of many environmental crises, in contrast with the sensational, spectacle-driven messaging that impels public activism today. Slow violence, because it is so readily ignored by a hard-charging capitalism, exacerbates the vulnerability of ecosystems and of people who are poor, disempowered, and often involuntarily displaced, while fueling social conflicts that arise from desperation as life-sustaining conditions erode. In a book of extraordinary scope, Nixon examines a cluster of writer-activists affiliated with the environmentalism of the poor in the global South. By approaching environmental justice literature from this transnational perspective, he exposes the limitations of the national and local frames that dominate environmental writing. And by skillfully illuminating the strategies these writer-activists deploy to give dramatic visibility to environmental emergencies, Nixon invites his readers to engage with some of the most pressing challenges of our time.

Book Description
Excerpt from Economic Plants of Porto Rico This paper includes miscellaneous information on the principal cultivated plants of Porto Rico, brief notes on many of the minor economic plants, and a list of all the native names of plants which have thus far been recorded from the island, with references to the scientific names of the species to which t-hev are applied as far as these have been determined. As there are no botanical publications in either English or Spanish which give an even approximately complete treatment of the flora, it is believed that the present list of names and the brief notes accompanying will be found of use both to visitors and to residents of the island.
