Heavy monsoon rains last month in Pakistan started the havoc and devastation, as rivers overflowed their banks in several provinces and torrential rainfall swept away peoples’ homes, infrastructure, crops, and livestock. The floods have killed at least 1,600 people, forced about two million from their homes and disrupted the lives of 14 million people. The United Nations appealed on Wednesday for $459 million in emergency aid for flood-ravaged Pakistan. These are the worst floods in Pakistan for more than 80 years.
