As water is a perishable resource, it is important to conserve as much water as possible. The tap water in Barcelona is safe to drink so there is no reason why students should be buying so many water bottles. Because IES does not have designated recycling bins, the plastic bottles are only going to waste. IES could provide students with plastic reusable water bottles at the beginning of each semester. By adding just a few more dollars to the tuition, IES could easily make back the money spent on the bottles and lest plastic bottles would go to waste.
