Politics act as the major obstacle in the way of genetically engineered food production.
The fact is that legal advances such as copy writes and distribution need to be taken care of first. Despite the advances in genetic food, some forms of these foods still need the aid of pesticides, which are harmful to the soil and insect life. For example Monsanto, one of the major players in GMO seeds has about fifteen people who hold high positions at Monsanto creating what opposers say is a conflict of interest.

Advantages: Can provide independent evidence for morphological and biological species. For bacteria and small organisms genetic species concepts can be very useful and save a lot of time.

It is also possible to get many samples from one individual. Disadvantages: This species concept also relies, to some extent, on human judgement of how much difference is enough to constitute separate species. Taking DNA can be invasive and unnerving for an animal, although many field studies can now use discarded hair, feathers, skin and so on for sequencing. Communicating with non-specialists about DNA taxonomy can also be very difficult. This species concept also uses DNA, but covers organisms that reproduce asexually to give rise to exact genetic copies of themselves. Disadvantages: Some organisms may reproduce asexually, but have high mutation rates and are thus not identical copies. The cladistic species concept relies on the possession of certain shared, derived characters called synapomorphies among individuals.
This is used to describe populations that are adapted to certain ecological niches and because of their adaptations will form discrete morphological clusters. Advantages: Acknowledges the role the environment plays in controlling morphological development. Disadvantages: Can miss cryptic species. Niches tend to be assumed and are difficult to define completely. Many taxa exploit overlapping resources, or can suddenly switch if a resource becomes scare.

Many ducks will mate with ducks of other species, so just because mating is observed it can, in some instances, be misleading. In some cases the ducks are still closely related enough to produce viable offspring hybrids , although the parents are members of fairly distinct species. This is different from the biological species concept, as all that has to occur is a mating attempt. Some species have very clear concepts of members of their species of the opposite sex, while others can get confused about sex and species. Advantages: Does have a mechanism-based test, albeit not a particularly reliable one. However, this concept can help to outline research questions. I saw a male of species x mate with a female of species y, do they produce viable offspring?
Also a non-invasive, observational concept. Other qualifiers can be added to this concept to cover what happens after mating.
