The north was heavily dependent on industry while the south was dependent on agriculture. The southern economy was based on the free work they were getting from slaves the north did not need slaves as they were less dependent on agriculture

In February of this year, the Human Fertilization and Embryology Authority in the United Kingdom approved a request by the Francis Crick Institute in London to modify human embryos using the new gene editing technique CRISPR-Cas9. This is the second time human embryos have been employed in such research, and the first time their use has been sanctioned by a national regulatory authority. The scientists at the Institute hope to cast light on early embryo development—work which may eventually lead to safer and more successful fertility treatments.
The embryos, provided by patients undergoing in vitro fertilization, will not be allowed to develop beyond seven days. But in theory—and eventually in practice—CRISPR could be used to modify disease-causing genes in embryos brought to term, removing the faulty script from the genetic code of that person’s future descendants as well. Proponents of such “human germline editing” argue that it could potentially decrease, or even eliminate, the incidence of many serious genetic diseases, reducing human suffering worldwide. Opponents say that modifying human embryos is dangerous and unnatural, and does not take into account the consent of future generations.
Answer:
Hunting and gathering
Explanation:
In Hunter-gatherer societies food is obtained by hunting fauna and gathering the flora which grows naturally in a region. The food is not obtained via agriculture.
Due to the foraging habits of Hunter-gatherer's they consume all the resources of the region and move to another region. They are grouped according to kinship. The nature of marriage they have is initially matrilocal where the child is cared for by the women of the mother's family.
The north used the rising number of immigrants to staff the industrial economy and the south felt no need to employ immigrants on their plantations because the invention of the cotton mill had made slavery a more economical option. :)
