The question that must be asked is is that enough to sustain his level of activity without starving? The book states, on page 17, that Watney needs to consume 1500, and he would still starve a little. It is vital to note that this number does not include calories allotted for physical labor. However, in late 2012, NASA conducted a study to compare the caloric
The ever increasing demand for food and other basic needs has put a lot of pressure on the plant genetic resources (PGR) and diversity particularly in agricultural sector in terms of addressing the accompanied challenges associated with increasing crop productivity. The utilization of PGR in agriculture has not only brought about profound changes in the crop productivity and quality, but has also opened up newer and unforeseen potential vistas including improvement of novel traits by domestication
