It is clear that releasing pet into the wild has become a new issue to many current governments. Governments should spend a great amount of money on keeping away wild animals from society, especially those which represent a menace to them. For example, Iguanas, which were common pets in the past, became a problem to the people´s health and produced a deterioration of plants and buildings. Similarly, other pets which will be let free into nature will carry out new unexpected problems that a government will have to face. To conclude, other important issues will be definetely set aside such as education, health, child under- nutrition and so on.
