Use of technology for affluent societies and poor societies

The 1950s are often seen as a counterpoint to the decades that followed it — a period of conformity, prosperity, and peace (after the Korean War ended), as compared to the rebellion, unrest, and war that began in the 1960s. However, the decade was not without its problems. Many domestic and foreign policy issues surfaced in the '50s that the United States would grapple with in the years ahead. Throughout the country, while many Americans enjoyed the fruits of an “affluent society,” poverty was more widespread than most believed, and the struggle for civil rights by minorities, particularly African‐Americans, became a national concern. Internationally, the Cold War continued. Although Eisenhower initiated the first steps toward improving relations with the Soviet Union, the United States became involved in Southeast Asia and offered pro‐Western governments in the Middle East and Latin America financial and military support. Poverty often causes people to put relatively more pressure on the environment which results in larger families (due to high death rates and insecurity), improper human waste disposal leading to unhealthy living conditions, more pressure on fragile land to meet their needs, overexploitation of natural resources and more deforestation. Insufficient knowledge about agricultural practices can also lead to a decline in crop yield and productivity etc.

Six amino acids have side chains that are polar but not charged. these are serine (ser), threonine (thr), cysteine (cys), asparagine (asn), glutamine (gln), and tyrosine (tyr). these amino acids are usually found at the surface of proteins, as discussed in the proteins 2 module.
