How is natural selection different from artificial selection?

Natural selection is when the traits that make an organism survive and reproduce better in their environment become more common. An example of natural selection would be light moths changing to dark-coloured moths to adapt to their environment. Like the tree barks they live on turning black, they too would turn dark-coloured for better survival and an advantage to hide from predators.
Artificial selection is intentional breeding for certain traits. An example would be a florist breeding two pretty plants to get a pretty plant..yeah, bad example but you get the idea lol.
