What are the ethical considerations in genetic engineering of plants to reduce allergenic pollens like Blue Lyme Grass?

The ethical considerations around the genetic engineering of plants to reduce allergenic pollens, such as with Blue Lyme Grass, are broad and multifaceted. The primary concern is the potential unforeseen consequences of tampering with nature. Despite the intention to alleviate allergic reactions, unpredictable side effects within the ecosystem could arise, impacting biodiversity.

Simultaneously, there's the issue of genetically modified plant cross-pollination affecting non-genetically modified species. This raises questions around the contamination of naturally occurring species and could lead to issues regarding their propagation.

Another consideration is the pressure such development piles on the farming industry. There's a risk that genetically engineered species could be perceived as 'necessary' to compete, leading to monoculture farming, which is detrimental to biodiversity and ecosystem health. Also, the high development and purchase costs of these engineered plants could unfairly disadvantage smaller or poorer farmers.

There's also ethical consideration around public consultation in the matter of genetic engineering. If a significant portion of society might be affected by it, it's crucial to ensure transparent dialogue, and the opportunity for public opinion to be heard.

Finally, there's the 'playing God' argument, questioning whether humans have the right or authority to alter natural systems in this way. These are just a few of the complex ethical considerations surrounding genetic engineering to reduce allergens in plants.
