The first is by increasing the land under cultivation, and the second involves increasing farming yields, or the amount of food that is produced per unit of cultivated land.</span> </p> <p> <span style="font-size:12pt;font-family:'Times New Roman'">The solution to this problem certainly does not lie in the extremes; there is a very limited amount of arable land available for farming, and constantly clearing land for cultivation only means that the U.S will run out of land for any other use at some point in the future. On the other hand, focusing on only maximizing land yields will mean increasingly intensive use of fertilizers, pesticides and other chemicals used by modern agro businesses.</span> </p> <p> <span style="font-size:12pt;font-family:'Times New Roman'">Unfortunately for us, XXXXXXXXX XXXXXXXXXX use is XXXXXXX commonplace, XX demonstrated XX a XXXXX increase in the productivity of cultivated XXXX, XXXX fertilizer use XXXXXX tripling in XXX last XXXXX XXXXXXX, while the per capita area XXXXXXXXX has declined and the global XXXXX use of XXXX XXX XXXX cultivation has XXXXXXXXXX (Thomas XXXX).

They also XXXXXXX the growth of XXXXXXXX XXXXX species, which XXX grow quickly and XXXXXXXXXXX XXXXXXXXXX arable XXXX (Tilman XXXX).</span> </p> <p> <span style="XXXX-size:XXXX;font-XXXXXX:'XXXXX New XXXXX'">XXXXXXX, XXX solution lies in XXXXXXXX fertilizer use XXXXX finding XXXX to compensate for the XXXXXXXX in XXXX production. XXXXXXX solely on XXXX use, as discussed above, is not a sustainable XXXXXXXX; as such, XXXXX XXXXXXX XXXX come into XXXX.</span> </p> <p> <span style="font-size:12pt;font-XXXXXX:'Times New Roman'">XXXXX include XXXXXX XXXXXXXX in crop genetics to XXXXXXX XXXXX that are XXXX resilient and XXX XXXXXXX higher yields XX XXXXXXX (Tilman XXXX), promoting XXX XX XXXXXXXXXXX XXXXXXX to XXX XX-XXXXXXXX XX XXXXXXX, manure, XXX leguminous cover XXXXX (Thomas 2014).
