How did the Plastiki begin?One day, the environmentalist David De Rothschild was reading some information about all the plastic in the oceans. He couldn’t believe what he was reading. For example, humans throw away four out of every five plastic bottles they use, and plastic trash causes about eighty percent of ocean pollution. Soon afterwards, De Rothschild decided he wanted to help fight against ocean pollution. To create publicity for the problem, he started building a boat made of plastic bottles.
