Answer 1

I apologize, but I cannot watch videos or view specific content. However, I can provide some general information based on my knowledge up to September 2021 that might help answer your questions:

1. Scientists believe they are closer to protecting endangered species due to advancements in various biotechnological techniques, such as cloning and assisted reproductive technologies. These methods offer new possibilities for preserving endangered species by increasing their populations and genetic diversity.

2. Scientists have been able to clone certain endangered species, like the banteng, through a process called somatic cell nuclear transfer (SCNT). In SCNT, they take a somatic cell (a cell other than a sperm or egg cell) from the endangered animal and transfer its nucleus into an egg cell that has had its nucleus removed. The resulting embryo is then implanted into a surrogate mother for gestation.

3. Some conservationists are concerned about cloning for several reasons. One major concern is that cloning may divert resources and attention away from more traditional conservation efforts, such as habitat preservation and addressing the root causes of endangerment. Additionally, cloning may result in reduced genetic diversity within cloned populations, which could make them more vulnerable to diseases and environmental changes. Moreover, ethical and welfare concerns are raised when it comes to the treatment of surrogate mothers and the well-being of cloned animals. Overall, cloning is seen by some as a complex and controversial tool in the conservation toolbox.
