The negative points of cloning greatly outweigh the positive. This is proved by the fact that cloning is currently illegal in Australia, so other people must feel the same way.
With plant cloning, the genetic makeup is the same for each clone made from the same DNA. If the original DNA has a disease, all of the clones will have it too. Plant clones will also be vulnerable to the same diseases and environmental factors as the original plant. This means that if all the cloned plants are in one area together and one plant gets a disease there is a very high chance all of the other plants are going to get the disease too.
Another disadvantage is that plants might not be able to reproduce normally as they were not made as other natural plants were. This would mean that cloning would need to be a permanent way of plant reproduction, so it would not necessarily be a solution to plant reproduction.
If cloning of animals was done on a large scale there would be no variation in animals and the current theory of evolution, natural selection would no longer exist. (Natural selection is when the animal best suited to the environment survives i.e. 'survival of the fittest).
If human cloning was made legal in Australia it would have many negative impacts on society. It would have a significant effect on the religious community as it may conflict with religious beliefs. For example many religious groups believe that human clones would not have a soul and that removing the nucleus from the cell is murder. Religious group may also be opposed to the fact the human cloning would mean gay/lesbian couples would be able to have children together. It can also be thought that cloning is like "playing...
