Lucknow, Sep 25 - After becoming the first Indian teenager to address the United Nations General Assembly on global climate change, Lucknow girl Yugratna Srivastava aims to notch another first - plant one million trees in the country.

'It would be history in the true sense if I manage to accomplish my big plan of planting one million trees in my country,' Yugratna, who arrived here Friday from the US, told reporters.

'I told the top world leaders and environmentalists about my big plan during the summit held Tuesday in New York and even submitted a copy of it to the executive director of the United Nations,' she added.

Asked how she would transform her plan into reality, the 13-year-old, a student of Class 9, replied: 'Primarily with the support of children in different regions of the country I want to get my plan executed. Of course, assistance from government agencies will also be required.'

Speaking of her experience at the summit, Yugratna said: 'For me it was a great opportunity... awesome. I think the opportunity I got comes once in a million times... Infact, I cannot put my feelings into words.'

'You can yourself gauge the thrill and the excitement, if you have US President Barack Obama listening to your speech.
