Deforestation, pollution and loss of natural resources all are possible due to human involvement in devastating the environment i.e. urban sprawl. Thus, correct answer is option D.
Further Explanation:
Urban sprawl is another word used for urbanization. This refers to the migration of the population from the populated towns as well as cities to the reduced density of residential development. This shift generally leads to reduction of natural resources and supplies. The final result is the spreading of a city over more and more rural land. This refers to the expansion of poorly planned and low-density development. This spreads over large amounts of land and puts long distances between storage home and work, and thus, creates high segregation between commercial and residential uses having harmful impacts on the individuals living in such regions. The wildlife and ecosystems are displaced.

However, it has many uninvited consequences for the environment as well as residents like higher water and air pollution, elevated jams and fatalities in traffic, and loss of agricultural capacity. There is also an increased car dependency.
