In response to the BP oil spill disaster in the Gulf of Mexico, Chelsea Green Publishing and biologist and commercial salmon “fisherma’am” Riki Ott are making her book about the Exxon Valdez spill in Alaska, Not One Drop, available for free download indefinitely on starting today. In exchange, Ott, who is on the coast trying to help communities in the path of the spill, and Chelsea Green president and publisher Margo Baldwin are asking that those who download the book donate at least $1 to Global Green USA (, a nonprofit dedicated to support those affected by the disaster. Baldwin said she believes the partnership has the potential to raise a lot of money for Global Green. Not One Drop, released in 2008, remains in print.
