As the population increases and farmable land becomes more scarce, growing food hydroponically in skyscrapers has been studied as an alternative way to grow food without incurring some of the common costs associated with farming (transportation to cities, pesticides, etc.).

What are some of the variable and fixed costs that are impacted by hydroponic farming? (Response should be at least 500 words with at least two outside references in APA format)
