Answer: This is an opinion question so I will give you the facts so you can form your own opinion for this answer.

Explanation:

<u>PRO GMO:</u>

Manufacturers use genetic modification to give foods desirable traits. For example, they have designed two new varieties of apple that turn less brown when cut or bruised.

The reasoning usually involves making crops more resistant to diseases as they grow. Manufacturers also engineer produce to be more nutritious or tolerant of herbicides.

Crop protection is the main rationale behind this type of genetic modification. Plants that are more resistant to diseases spread by insects or viruses result in higher yields for farmers and a more attractive product.

Genetically modification can also increase nutritional value or enhance flavor.

All of these factors contribute to lower costs for the consumer. They can also ensure that more people have access to quality food.

<u>CONS of GMO</u>

Because genetically engineering foods is a relatively new practice, little is known about the long-term effects and safety.

There are many purported downsides, but the evidence varies, and the main health issues associated with GMO foods are hotly debated. Research is ongoing.

Some of the cons include: Allergies, Cancer, antibacterial resistance, and outcrossing which refers to the risk of genes from certain GMO plants mixing with those of conventional crops.
