Innocent fun: The good folk at Innocent are once again planning to plant a tree for every carton of their smoothie sold and registered on their website in May.

It is the second year of the company's pleasingly titled Buy One Grow One Tree campaign.

According to the company, last year's campaign saw 164,020 trees planted in India. The campaign will run throughout next month on both big cartons and packs of Innocent kids' smoothies.
