Tetra Pak and WWF Hungary's competition was popular

8,000 pupils take part on the competition's first round. 280 groups go ahead to the second round, where pupils have to make posters about environment protection and making photos about protecting the nature.

 Tetra Pak and WWF have signed a three
year agreement in 2006 to globally cooperate in forestry and climate
change programmes. In 2007 the company started an extra program with
WWF's Hungarian daughter. This competition is a part of the
international and domestic program.
