Here's one of the better locals ads I've seen. it's for a not-for-profit org.
The headline reads "The price of filling up with agro-fuel." Swissaid argues that in extreme cases, the agro-fuel boom will lead to people dying "because valuable land will be used to grow energy plants, leaving them without enough to eat."
It's a weighty issue. Swissaid could have loaded this up with body copy and bullet points. Instead they went for a simple, targeted execution. Nice job.
