Why is it done?

There are many reasons why genetic engineering is done, but these are some of the more well-known and common ones.

Agriculture: For agriculture, genetic engineering can be used to better the food we grow. They can add genes that make it more efficient in growing, thriving in their areas or conditions and much more. As well, genes can be added to the organism to make it more nutritious or bigger or have less negatively effecting things.

Medicine: Animals can be engineered to be born with specific sicknesses and be tested on with cures that can also be used on humans.

Endangered species: Endangered species can be cloned and, in some cases, modified to be able to adapt to more territories. This can increase their numbers and better their chances of survival, possibly taking them off the endangered list.

Research: Researching the organism can help us understand them better and hopefully understand how they can cope more easily.

Donating Organs: Now, some scientists are considered engineering specific animals to have organs compatible to humans so we have more organs for those that need them.

Cloning Pets: In some places, there is now an option to clone your pet, to make it exactly the same instead
of getting a new one.
