Spread The Net, spearheaded by Rick Mercer and Belinda Stronach, is a campaign geared toward raising money for a simple solution: bednets. Bednets are perhaps the most effective method of combating malaria, protecting a child in their sleep for up to five years.
Students from all across Canada have been asked to show their support to this cause by raising awareness and promoting this campaign.
