Pollution, Pollution, population growth and over consumption, and finally habitat loss
The correct answer to this open question is the following.
This is the summary.
Frederick Douglass was an African American reformer and abolitionist who, on July 5, 1852, was invited a keynote speaker during the Independence Day celebration. There, he delivered a controversial speech about the impact of independence on black people living in America.
Right there, in the Corinthian Hall of Rochester, in the state of New York, Douglass delivered a controversial speech nobody expected. He set the tone of the speech since the very beginning of his words when he literally said "This fourth of July is yours, not mine. You may rejoice. I must mourn."
That really caught people's attention. And that was just the beginning.
In his speech, Douglass recognized the value and courage of the United States founding fathers but clearly established that those rights stated in the US Constitution were not for everyone. They were just for the white people. Not the African American people who have been suffering for racist segregation and most in the South were suffering because they were slaves.
I believe preamble was created to be able to give the people a correct justice and welfare.
Thus, this words are used as personification.
Why?
because this was referred to a person.
A person needs right welfare and justice that's why they pushed this preamble to be able to give the people what they deserve to have. And to be able to have an equal society for prosperous country.
