Are scientists bringing back dinosaurs?

Are scientists really attempting to bring dinosaurs back to life? If so, how are they doing it and what technology is involved? Are there any ethical concerns surrounding this practice? Could this potentially have a negative impact on the environment or other living creatures? And, most importantly, what would be the benefits of having dinosaurs roaming around in our modern world? These are just a few of the questions that come to mind when I hear about this fascinating yet controversial topic.
