Should we resurrect extinct species?

Summary: I know this topic may make you think Jurassic Park but it is something that will be coming very soon. So prepare yourself for the debate of should we bring back extinct species? First question. Is it possible?  Yes. and is being researched as we speak. Second question. How is is possible? Well there are many approaches scientists have in mind such as gene editing.Gene editing is when you take pre existing genes in de extinctions case the closest relative to the animal and taking genes from the old animal and mixing/editing them. It is like having lines of code. Then deleting a few and adding in new phrases. It changes the code all together. Then you have cloning. This is where you try to make an identical copy of the old creature. The ways they have tried doing this is by switching out the nucleus from the closest relative with the nucleus of the old animal in the starter cell of the baby and fertilizer it and let it be born naturally. Those are just two ways to do it but there are many more ways science is leading us towards the day we could have mammoths or other extinct species roaming the earth.

S&EP: Asking Questions, Defining Problems:
With looking at all these informational articles and sources on this very complex and multifaceted topic we had to look at all the different issues. We needed to see what was really going to need to happen before any of this cool stuff could place a foot on this earth. For example, what would it cost to  bring back these species? It can't be cheap to make all of these crazy things happen. The answer to that is it could cost millions and millions of dollars to get a stable species of lets say wooly mammoths on earth. This of course is a problem because as one of the articles says when you make a choice to spend all this money to bring one species back you are also making the choice to let many other endangered species die off when you could have helped them. Another thought we had to look into is when these animals come will they be an invasive species and help endanger other species? Or will they be the top of the food chain and create a giant trickle effect on an ecosystem? These are the questions we must answer before we bring back any animals.


XCC: Stability and Change:
When it comes to de extinction you have of course many things that are unknown. Since this has never been done before and most of the animals we are looking at came before our time there is a lot of unpredictability. One major thing is what role will these animals play in our world? Most scientists working on bringing back these animals say that they can help balance out the environment and prevent global warming. For example the  wooly mammoth will be put in the Tundra. It would be useful in the sense of stopping global warming because it can stomp down the snowy floor helping lock in the carbon that is trying to come out. There is so much carbon trapped that if it gets loose it will double the amount of carbon already in the air. Yet of course as I said before we can not make promises that these animals won't be an invasive species or a top predator. We don't know how stable the world will be after they leave there effect. We truly must be ready for all that can come with this big change!
