This represents not only a value financial savings but in addition benefits the atmosphere in that no chemicals are being released into the air. Lastly, we should consider the environmental impacts of transportation. As hydroponics allows produce to be grown domestically and requires fewer areas to import their crops, there is a reduction in each value and greenhouse gas emissions on account of reduced transportation necessities [source: Jensen].
