How is machines an example of the concept of globalization

Answers

Answer:

This globalization and free trade machine is constantly exploiting, depleting, and abusing people of the developing world as well as their resources yet it provides absolutely no benefits to the greater working of the planet. The diagram of the machine is missing one key by-product or output per say, which is injustice. You see the natural resources are taken from already impoverished countries, who do not have the means to fight for the conservation of their environment. From these resources, the capitalistic world that we live in emphasizes and encourages materialism which drives production of consumer junk that is not necessary or needed and ends up as waste and pollution back into the natural environment. The labor force needed to provide for the huge demand of junk from the western world is made up of people from poor communities who will work ten-hour days in inhumane conditions making barely enough money to feed themselves. These people will also be unequally affected by the effects of the inevitable pollution and emissions, which come out of the globalization machine and create further problems for the planet and its inhabitants. This can include environmental degradation, negative human health impacts, global warming, infertile land, and ozone layer depletion. Once put into perspective this machine is destroying the well-being of the earth and all of its citizens including fauna and flora. The world is in need of a new machine driving a different world system. In reality, the world should not be based on one machine but on many different ones, which take into account the history, culture, and background of all countries and peoples to ensure all processes within the machine are fair and equal to all.

Answers

Answer: 0.1km

Explanation:

The first thing to do in order to solve the question is to convert all into thesame units.

100cm = 1m

1000mm = 1m

1000000 mm = 1km

1000m = 1km

A. 3500cm = 3500/100 = 35m

B. 65.5m

C. 75000mm = 75000/1000 = 75m

D. 15.5m

E. 0.1km = 0.1 × 1000 = 100m

Based on the calculation above, the longest distance is 0.1km.

How are the 1968 democratic convention and the letter from national mobilization committee similar and different?

Answers

Answer:The 1968 democratic convention and the letter from national mobilization committe similar Though the 1968 protest at the Democratic National Convention were largely against the Vietnam War, the country was undergoing unrest on many fronts. The Vietnam War was in its 13th year and the recent Tet Offensive had proved the conflict was far from over, as the draft sent more young men into the fray. It was only a matter of time before a showdown would take place between the government of President Lyndon B. Johnson and America’s war-weary citizens.

Explanation:

The Democratic Party in 1968 was in crisis. President Johnson—despite being elected with a huge majority in 1964—was soon loathed by many of his peers and constituents due to his pro-Vietnam War policies.

In November 1967, a relatively unknown and unremarkable Minnesota senator named Eugene McCarthy announced his intent to challenge Johnson for the Democratic presidential nomination. In March 1968, McCarthy won 40 percent of the vote in the New Hampshire presidential primary, thereby validating his candidacy.

A few days later, Senator Robert F. Kennedy abandoned his support for Johnson and entered the presidential fight.

President Johnson saw the writing on the wall and, on March 31, told a stunned nation during a televised address that he would not seek reelection. The following month, Vice President Hubert Humphrey—backed by Johnson—announced his candidacy for the nomination, further dividing the Democratic Party.

Humphrey focused on winning delegates in non-primary states, while Kennedy and McCarthy campaigned hard in primary states. Tragically, the race was turned upside down again when Robert Kennedy was assassinated after giving his victory speech following the California primary on June 4.

What are the strongest three arguments that go against Kaepernick’s decision to kneel during the national anthem?

Answers

Answer:

Explanation:

Pro 1

When one believes the United States is not living up to its ideals of freedom, liberty, and justice for all, kneeling during the national anthem is appropriate and justified.

Colin Kaepernick said, “I’m not going to stand up to show pride in a flag for a country that oppresses black people and people of color… To me, this is bigger than football and it would be selfish on my part to look the other way. There are bodies in the street and people getting paid leave and getting away with murder.” Many other athletes have since refused to stand for the national anthem for similar reasons.  Denver Broncos linebacker Brandon Marshall, who also has knelt during the national anthem, said, “the message is I’m against social injustice… I’m not against the military or police or America at all.”  NASCAR official and Army veteran Kirk Price, who kneeled during the anthem at a June 2020 race, stated, “I fully respect the flag… That’s not what the issue is here. The issue is African Americans being oppressed for so long under the flag… But to be honest with you, I know what the flag stands for and I know about Black people being oppressed because I am one.”

Con 1

Kneeling during the national anthem shows disrespect for the flag and members of the armed forces.

The national anthem pays respect to the people who have risked their lives, been injured, or died defending the United States. Carole Isham, a great-great-great-granddaughter of the writer of the national anthem (Francis Scott Key) stated that “it just blows my mind that somebody like (Kaepernick) would do what he does to dishonor the flag of this country and the national anthem when we have young men and women overseas fighting for this country, people that have died for this country.” Drew Brees, New Orleans Saints quarterback, supported Kaepernick’s message but disagreed with the delivery: “t’s an oxymoron that you’re sitting down, disrespecting that flag that has given you the freedom to speak out.” Brees reiterated his position on June 3, 2020 in the wake of the George Floyd killing. However, in light of the backlash that followed, Brees retracted his statement. In reaction, on June 5, 2020, President Trump tweeted, “OLD GLORY is to be revered, cherished, and flown high… “We should be standing up straight and tall, ideally with a salute, or a hand on heart. There are other things you can protest, but not our Great American Flag – NO KNEELING!”

Pro 2

When a national figure such as an NFL player kneels during the national anthem, it shocks people into paying attention and generates conversation.

Many people were shocked and offended when Colin Kaepernick refused to stand for “The Star-Spangled Banner,” and the resulting debate has continued as additional players joined the protest. NFL Commissioner Roger Goodell originally disagreed with those actions, but later praised what he called a movement from protest to progress: “I truly respect our players wanting to speak out and change the community… We want them to use that voice.” Social media has given a voice to strong opinions on both sides, including members of the armed forces who express support Kaepernick’s right to protest by posting under the hashtag

Con 2

Kneeling during the national anthem is an ineffective and counterproductive way to promote a cause.

Clemson University football coach Dabo Swinney said in a press conference: “I don’t think it’s good to be a distraction to your team. I don’t think it’s good to use your team as the platform.”  President Obama expressed concern that not standing for the national anthem can get in the way of the message: “As a general matter, when it comes to the flag the national anthem and the meaning that holds for our men and women in uniform and those who’ve fought for us — that is a tough thing for them to get past to then hear what his [Kaepernick’s] deeper concerns are.” Malcolm Jenkins, safety for the Philadelphia Eagles, supported Kaepernick’s message but said, “My grandfather served [in the military]. And this is a country that I love. So, me not standing for the national anthem isn’t really going to get me the results that I want.”

Answers

This excerpt contributes to the effect of Winthrop's message to his audience by emphasizing that "the success of their mission depends on how closely they follow their agreement with God."

This is evident when he said that "Now if the Lord shall please to hear us, and bring us in peace to the place we desire, then hath He ratified this covenant...and will expect a strict performance of the articles contained in it...

This implies that for God to help them achieve their success, they must abide by their agreement with God which is "a strict performance of the articles contained in it."
