New eugenics

New eugenics is a type of science that some people believe should be used to try and improve the quality of humanity. It involves making choices about who gets to have children and who doesn’t. This could be done through taking out certain genes, which some people think could lead to healthier and smarter people. It could also involve giving certain people advantages in society like more education or better healthcare. New eugenics is a controversial idea because it could be used to favor certain groups of people and treat others unfairly.
