Very well researched and written book about the moral and ethical issues of conservation efforts, past, present and future. The concept of "de-extinction" is fascinating but raises many unanswered questions. If we can resurrect an extinct species from genetic material, will that stop current conservation efforts because people will think "So what, we can always bring them back later". What about habitat descruction? Will the resurrected animals truly be a part of the original species without the usual environmental and social interactions?
This book really helps drive home that we humans are stewards of this little blue marble and right now we are doing an atrocious job. On a scale of 1 - 10 we don't even rate.
