improving tourism industriy is positive or a negative development?


These days an increasing number of developing countries are improving their tourism industries. Why do you think this is the case? Is this a positive or a negative development?





For most developing countries tourism is a major way of earning foreign reserves. And it can be seen that recently most developing countries put more effort on developing its tourism sector. However it is believed that this has positive as well as negative effects which can be broadly discussed in terms of social, cultural and economical perspectives.

        Developing tourism industry derives lot of advantages to developing countries. Firstly it brings lot of foreign exchange to countries. And it will be a good method to lower the financial deficit. Also tourism can be used to promote traditional business to the international trade community. On the other hand, governments invest lot of money on infrastructure development to support tourism.

        However improving tourism industry has several negative effects. Most of time we have seen that lot of natural places are destroyed with implication of tourism development. And there are lots of incidents where tourists are prosecuted for illegal activities such as child abuse, animal trafficking and smuggling. It is believed that most developing countries have rich cultural habitats, especially Asian countries. Unfortunately it can be seen that with the tourism industry development these cultural aspects are shading from the society.

        Finally we can conclude that disadvantages of improving tourism cannot out weight the advantages. And it is authority’s responsibility to make sure they are following well planed long term approaches other than ad-hoc development activities.

using animals for medical tests

Generally when a new medicine is invented scientist extensively test it to make sure the product is safe for human. And it is believed that this is very complex and critical process. And some times animals are used in this process to make sure products are fit for the exact purpose. However using animals for medical tests has advantages and disadvantages for humans as well as for animals.

There are advantages of using animals to test the medicines. Because it is known that some human and animal organs are worked in similar manner. Therefore side effects and actual results of medicines can be reviled before applying for humans.

However there are advantages of using animals to medical tests. Firstly some important species can be irradiated from the earth because of uncontrolled use. And it will significantly affect the biodiversity of our planet. Secondly it is unethical to use animals for testing as all animal rights representatives are emphasizing. And some times it is possible to behave animal body different than human. Then developed medicine will not give expected results. Hence there is some risk factor of using animals for medical tests. And also there is possibility of introducing new deceases to humans. For and example it is believed that AIDS which is common among monkeys, is transferred to humans from animals.

Finally we can conclude that even there are serious disadvantages of using animals for medical tests they cannot out weight the advantages. And it is clear that the process of using animals has to be well defined and planned.
