Agreed. And if they do send people those people will almost certainly starve or suffocate.
Biosphere 2 is our best attempt at creating a self-supporting closed environmental system. At 3.14 acres stocked with complex (and sensitive) vegetation, air and water supplies and support machinery weighing an untold amount of gigatons costing $200-300 million with relatively cheap Earth-based construction techniques and labor - not to mention Earth solar insulation for power and vegetation growth unlike what will be available at Mars, it couldn't produce enough food or oxygen for a mere 7-8 people.
There is no way at anything near current or foreseen launch prices that anything like that could be duplicated on Mars, let alone exceeded.
