There is nothing wrong with development as such.
Development can create employment and help the national economy to grow.
However, too often developers see only the advantages of their project without thinking about the disadvantages. A correct assessment of a development project requires more than a study of the economic costs of the project to the developer, and of the benefits it is expected to provide. It should also involve an evaluation of the possible damage the project may do to the environment and people, and of the alternative possible uses of the resources, including the alternative of doing nothing at all. It is often people like you, who know the local environment and resources well, who will be the most sensitive to the good and bad effects of a development project on your environment. You must therefore learn how to deal with developers so that good projects can go ahead while serious environmental harm or social disruption from poorly-planned development projects can be avoided.
