Plant breeding is the science

and art of changing what they have and making it in what they desire it to be. They do this by arranging the different plants and changing there molecular patterns. They do this for higher varieties of protection by , pest resistance and diseases from getting to the plants.

Some people say that selective breeding can weaken the species

because it reduces the gene pool.

The other animals or plants become redundant and un-necessary.

It could cause genetic problems and the animal may become sick easier.

If it is a plant that needs more water then it would be creating an environmental issue.

Disrupts the food chain and the natural order of life.

Selectively bred animals are more likely to become extinct.

Cons

Selective breeding can be described as being

systematic breeding of animals in order to change certain qualities in them.

It can produce fitter, stronger animals or animals of a higher yield of milk, meat or eggs for example.

It can produce animals better suited to survive in poor climates or marginal conditions, thus preserving human food supplies and saving life.

It ensures the eradication of hereditary sickness in some blood lines.

Selective breeding rules out weakness and disability.

Naturally there is no laws against selective breeding.

There are some laws about genetically breeding crops that we will be eating.
