Genetic revolutions have been combating aging, eradicating diseases and allowing parents to genetically design a baby. This is shown in the movie My Sister’s Keeper where the parents genetically create a baby to be the exact donor match of their older daughter who had cancer, showing the idea that genetics is evolving and new research and ideas are coming out every day. The woolly mammoth went extinct 4,000 years ago. However, with current advances in genetics there is now a possibility of bringing it back. A new revolution in genetics is the CRISPR (clustered regularly interspaced short palindromic repeats). This tool allows scientists to place individual genes that code for specific characteristics into the genome of living creatures. Essentially, we can now write DNA. An advantage of this is to combat climate change and global warming. Basically, places where the temperature is continuing to rise can actually have their climate adjusted by re introducing certain large herbivores back into the region. By introducing these animals, it encourages the growth of steppe grass which has a high albedo effect, meaning it reflects sunlight back into the atmosphere which reduces the heat absorbed into the Earth and can actually lower the temperature by as much as 15°F. Specifically in the steppes, introducing the woolly mammoth can combat permafrost melting. The process involves using a carcass of a mammoth to sequence the genome. Since the mammoth is so similar to the Asian elephant, they would place the genes into the embryo of an Asian elephant and it would give birth to the mammoth. While it would be very beneficial in the global warming aspect, a lot has changed since woolly mammoths were around. A question scientists need to be asking is would the mammoth be able to adapt and live in our constantly changing climate, or are they strictly only able to live like they did 4,000 years ago? This could be a huge disadvantage of bringing the woolly mammoth back. If they are able to bring back the wooly mammoth, there is no telling where they will stop. They could end up bringing back many other extinct animals or even saving animals from going extinct in the first place.
