Prince Harry lavished praise and affection on climate activist Greta Thunberg late Sunday night, saying “every family needs their Greta” as he claimed “the whole world is paying attention” to her efforts. Harry took to the stage at the OnSide Awards at the Royal Albert Hall in London to make his gushing tribute. It was his final public appearance before he and wife Meghan take a break from their Royal dutuies and fly across the Atlantic for an extended six-week holiday in America.
