(CNN) -- After just two days of closed-door negotiations, the leaders who had gathered at the International Whaling Commission in Agadir, Morocco, announced no agreement was reached on the IWC chair's proposal to improve whale conservation. Greenpeace did not support the proposal, but we had hoped governments would change it to become an agreement to end whaling, not a recipe for continuing it. It is particularly disappointing to me, because my professional commitment to end the whale hunt in my country of Japan -- which led to the exposure of an embezzlement scandal at the heart of the whaling industry -- has come at significant personal cost.

The investigation I conducted with my colleague, @placeholder, led to our arrests in front of banks of media outlets who had been told about it in advance.
