A few years ago (2-4 years ago) the ELF or somesuch group burned down experimental crops at UCSD, ruining some graduate students' research work, and spray painted graffiti on the walls of the greenhouse or nearby buildings. Many of the plants were exotic or non-native plants, not artificially-genetically-modified plants.
The intersection of Towne Center Drive and La Jolla Village Drive is next to the UTC mall, just 2-3 miles from UCSD. The eco-terrorists must like this area.
