3) express your opinion about the need for sustainable development strategies.
are they necessary or not? explain your point of view. give examples to support your viewpoint.

There is a great need for sustainable development strategies. To start,  sustainable development is basically defined as economic development without the depletion of natural resources. In simpler terms that means there is no use of the natural resources. They are necessary, without them there would be no natural resources left. If there were no natural resources left, then it would basically act as a chain reaction within nature.Things would start dying without the resources they need to survive, and if it is effecting the animals, it will move up the chain to humans.
