resources have been depleted
When something is depleted, it has lost an essential aspect to its existence or ability to function. This expression particularly refers to the diminishment of energy, money, or resources, so can be used in either a social or professional setting, though the former is more common. It is quite a formal term, and something more likely to be heard on the news, or in an academic or political environment.
