Answer:
The poorer areas of the cities were characterised by overcrowded, badly built, unsanitary living accommodation, and filthy streets. Cholera, carried by dirty water, killed 16,000 Londoners in 1849 alone, and smallpox, scarlet fever, typhus, scurvy and rickets were rife.
Gibbon is able to make this claim since he shows that technological advances have skyrocketed since the Industrial Revolution, and he thinks this progress will continue thanks to the computer age.
That is for sure right I believe.
Dr. Martin Luther King Jr supported non-violent protest.
For example the Albany movement where Dr. King and peaceful demonstrators were all jailed. Later on they are freed from jail. The Birmingham campaign where protests were held against businesses that only hired “White” Anglo-Saxon Americans or had segregated restrooms. These protests would include sit-ins and marches, which would get them jailed. Dr. King encouraged the nonviolent protest in order for the jails to overflow.
