The seeds are grown in labs and are modified to resist pests and to tolerate herbicides. Twenty five percent of pesticides and herbicides used in agriculture are used on cotton. Airplanes, known as crop dusters, spray chemicals on the cotton crops during the growth of the cotton, then the tractors harvest the cotton once the cotton plant has matured. 18-wheelers are used to transport the bales of cotton from the fields to the factories. Once at the factory, the cotton goes through several processes. Many machines are involved in just getting the raw cotton ready to be made into a t-shirt. Some of these machines include, bale openers, combers, spinning machines, and knitting machines. Although most cotton production does not take place in the United States, it is shipped to other countries. This process involves ships that have negative effects on the environment, such as transporting invasive species and introducing them to new …show more content…
Climatic conditions for cotton production are least attractive in Syria, Egypt, Turkmenistan, Uzbekistan and Turkey because evaporative demand in all these countries is very high (1000-1300 mm) while effective rainfall is very low (0-100 mm) (Chapagain, Hoekstra, Savenije, & Gautam, 2005). Growing cotton here can lead in a rapid degradation of the already inefficient soil. The constant irrigation of the crops, required to keep the crops healthy, combined with the high evaporation rates will result in a high salinity content in the soil. Syria, Egypt, Turkmenistan, Uzbekistan and Turkey all have borders that lie next to a body of salt water. These countries all produce enough cotton to be listed in the top fifteen seed cotton producing countries, as shown in the table
