Some of the biggest sacrifices are going to involve the cessation of dumping of wastes into the ocean on the part of ships and aircraft which would require significant increases in costs for disposal and transport of those wastes. So shipping and airline companies would have to take financial hits which would be translated to the consumer in the form of slightly higher prices for airline tickets or the price of goods that are shipped overseas. So the sacrifices involve mostly consumers paying higher prices for things.
There would also need to be changes made to how pesticides and other chemicals are used so that they do not end up in watersheds and in the ocean. This would also result in higher prices for consumable goods including produce as farms and other growers have to shift costs for different production methods and perhaps lower yields to consumers.
