The environmental impact on animal agriculture is tremendous and is a topic for its own discussion.  In brief, animal agriculture uses an immense amount of the arable land on the planet, contributes to deforestation, water waste and contamination, antibiotic resistance, and greenhouse gas emissions [8]. Essentially, people who claim to be environmentalists but eat meat are hypocrites. It has been speculated that in vitro meat may result in up to 50% lower energy usage, 75-95% lower green house gas emissions, 99% lower land use, and 80-95% less water use depending on comparisons between products [9]. It is estimated that world population will tip 9 billion by 2050 with meat consumption increases estimated as high as 73% [10].  For these reasons, in vitro meat and other agricultural technologies offer the opportunity to severely mitigate the harmful effects of the current agricultural industry and should be welcomed alternatives to current practices.
