The ambassador made compelling presentations to the representatives of both groups, who were visibly moved by a video presentation of the destruction of Barbuda and the evacuation of all its residents to Antigua.
"The damage is complete", said Ronald Sanders, who has been Antigua and Barbuda's ambassador to the U.S. since 2015.
Sanders described the present situation in Barbuda, which he described as "uninhabitable", including the possibility of disease resulting from dead animals and unclean water infiltration.
"For the first time in 300 years, there's not a single living person on the island of Barbuda", said Antigua and Barbuda's Ambassador to the U.S. Ronald Sanders.
The roughly 1800 residents of the island have been evacuated to shelters in Antigua, the partner island to the Commonwealth nation, and are being housed in shelters there.
According to Sanders, Irma was "the most ferocious, cruel and merciless storm" in the island's history.
Sanders says the world must step up and help Barbuda. "The island and the people on the island had absolutely no chance".
The dogs will look for their next meal among the chicken, pigs, horses and goats, Karen Corbin, president of the Antigua and Barbuda Humane Society, told TIME.
Evacuees, including 500 children, were sent to Antigua, and were living in cramped government quarters and nursing homes, which Sanders said was "unacceptable".
Sanders told PRI the roughly estimated the cost to rebuild the island's infrastructure is US$200 million; a Canadian team that went into the island earlier this week is expected to provide more information.
"We are a small island community - the gross domestic product of Antigua is $1 billion a year", he told USA Today. "We can not afford to take on this responsibility by ourselves".
Prime Minister Gaston Browne called it "just miraculous" that only one person died due to the disaster. "We need to mobilise worldwide help from partner countries in the global community". "We can not cope with our own resources alone".
Mentioning that Barbuda has world-class beaches with pink sand and crystal clear water, he said the island is lovely for tourism.
"We believe climate change is here to stay - it's a reality, despite all of the naysayers", he says. "We, unfortunately, who contribute less than naught-point-naught per cent of the pollution of the world's atmosphere, are the world's greatest victims".
