The sustainable fishing is an example of sustainable development.
Explanation:
The sustainable development has its focus on sustainability, meaning that the area that is developed should be developed in a manner that will enable continuous production and availability of certain goods. This is done by undertaking certain measures, as the resources are not endless, so they have to be managed very carefully in order to be available year in year out. A good example of this is the sustainable fishing.
The sustainable fishing is performed in a manner that strictly regulates the amount of fish that is fished, in what period should the fishing go on, the size of the fish, as well as the species of fish. This results in leaving the fish to reproduce freely, always having high enough number for reproduction, releasing the young fish if caught, and having good supply of fish each year. This benefits the fish, the economy, the diet of the humans, and the well being of the environment.

Cellulose is a carbohydrate which is present in the plant cells. The cellulose is a polymer with glucose as the monomer units. The monomer units of cellulose is attached by the beta linkages. The cellulose provides structural support to the plant cells by forming micro-tubules. The humans cannot eat the diet rich in cellulose because they lack the enzymes that are needed to digest them. Some animals, such as cows and termites have these enzymes but not the humans.
Hence, the answer is 'people cannot digest cellulose'.
