Effects on Human Well-being

  • Biological resources (food security, medicines, building materials)
  • Ecosystem security (climate stability, soil condition, susceptibility to natural disasters)
  • Cultural value

Facilitated Adaptation - humans are lessening biodiversity thus it is our duty to fix it

Potential problems - #1 public perception

Unknowns

  • Could transgenic animals become invasive?
  • Can we develop the technology in time to make a difference?
  • Will GM animals reduce intra-species diversity?
  • Could the introduced genes have unexpected adverse effects?

Additional problems

  • Expense
  • Very difficult to actualize this technology from start to finish
  • Ethical considerations of animal testing
  • Generation of transgenic animals will require sacrifice of precious individuals left in a species
  • Diverts focus away from habitat restoration

Considerations

  • Which species should be targeted?
  • What kinds of genes should we introduce?
  • Who will oversee the creation and care of GM animals?
- genes:
enable animals to survive harsher climates?
eat different foods?
reproduce faster?
grow up quicker?
resist diseases?
all of the above?

Months required to produce GM crops

It takes 6-15 years to generate new GM crops from science to first sale - we can expect at least that amount of time for animals.

Total time is closer to 22 years.

Research alone takes ~4 years - we need to start right now.

A last chance solution

- At the end of the line, we may have only 3 options: let the species die, move the animals, or change the animals
- Moving animals could introduce invasive species, diseases to otherwise stable populations, the travel itself might also kill off animals.
- In this case, controlled transgenic experiments are the obvious best choice
