The American Museum of Natural History says it is exploring its options after discovering that the honoree at a gala to which it rented space next month will be President Jair Bolsonaro of Brazil, whose environmental policies have come under fire.

In statements Thursday and Friday, the museum responded to criticism that an institution dedicated to nature and science would serve as a podium to honor someone who has proposed opening up more of the Amazon rain forest to mining and agribusiness.

The event is an annual gala honoring a Person of the Year Award organized by the Brazilian-American Chamber of Commerce, a nonprofit that promotes business and cultural ties between the United States and Brazil.

The museum said it had agreed to book the event this year before it learned who the nominee would be, and its remarks suggested it might be considering whether there is any way to back out of hosting the engagement.
