Nobel Peace Prize laureate Wangari Maathai says people worried about the environment should rely less on government and more on themselves to protect the planet's limited resources. Maathai, a Kenyan environmentalist who won the Nobel prize in 2004, said people who recycle and plant trees have a bigger influence on the planet's health than elected leaders. Even nations with the best intentions fail to meet expectations, she said, citing the Kyoto international treaty as a prime example.
