Answer:
Unmanaged development like that traditionally used in the mining industries in developing countries are an example of the destruction that this development can cause. If not regulated, this industry can damage the local environment.
Step-by-step explanation:
Unmanaged development can lead to a lot of unsustainable practices that do little to benefit the local population where the development project is transpiring for example. An example would be mining companies that enter a country that is mineral rich like Peru and that pay the national government for the right to mine minerals and precious and semi-precious metals from the subsoil. However, if unmanaged, the mining company will make use of local water supplies that can affect surrounding communities. They also tend to pay local workers less and they do not offer them benefits for the long term health effects that can come from working in the mining industry. There are fewer protections for workers and local populations in countries where there is less regulation. This can have a negative impact on the local population and the local environment by contaminating land and water, for example.
