===Earth Day 2010 protests against coal===
On Earth Day 2010, 4,000 environmentalists protested in solidarity with rallies in Tampakan, South Cotabato, and Maasim, Sarangani, to protest the against the coal-fired plant project of [[CONAL Holdings]], and mining activities in these provinces.
Protesters in Sarangani included leaders of religious groups, fishermen, indigenous people, and foreign divers who said the project will destroy the waters of Maasim, because of the area's ecologically important coral reefs. Mindanao State University students dressed as Na'vi from the film Avatar marched toward the fenced property of the proposed plant site. The protesters and media were refused entry to the CONAL Community Development Office. A slight commotion occurred when four unidentified men suspected to be working for CONAL were seen with cameras, video recorders and handheld radios at the rally.<ref name="avatar">[http://ph.beta.promo.yahoo.com/purple-thumb/editors-log-article?blogid=editors_log&postid=142&viewPost=1 "Rallies vs coal plant, mining mark Earth Day in Soccskargen"] Yahoo!
