They are less biologically diverse with only one or two tree species; they are much less biologically diverse and less sustainable than old-growth & secondary forest b/c they violate nature's biodiversity principle of sustainability. Also, repeatedly cutting and replanting depletes the topsoil of nutrients and can lead to an irreversible tipping point that hinders the regrowth of any type of forest, and there is controversy over the increased use of genetically engineered tree species whose seeds could spread to other areas and threaten the natural diversity of second and old growth forest. Describe how papermaking can occur tree-free. Why is this method better than using pulp from trees? China uses rice straw to make much of its paper.

Most tree free paper is made from the fibers of a rapidly growing plant called kenaf. Kenaf another non-tree fibers make more paper per area of land than tree farms and require fewer pesticides and herbicides. Kenaf paper is brighter and stronger and have less environmental impact than papers made from pine fibers.

One reason for this is kenaf fiber is lighter colored than tree fiber and requires less bleaching (potential harmful chemicals). Kenaf fibers takes approx. 20% less energy to make than tree fiber.

Establish small plantations of fast-growing fuelwood trees and shrubs around farms and in community woodlots. Burn wood more efficiently by providing villagers with cheap, fuel efficient and less polluting wood stoves Switch to burning garden plant wastes such as roots of various gourds and squash plants (Scientist are trying to produce charcoal out of such waste for heating and cooking) Ending government subsidies that pay for new logging roads and subsidizing the planting of trees to help increase forest cover worldwide. It is an area of habitat connecting wildlife populations separated by human activities or structures (such as roads, development, or logging; they are meant to demonstrate a balanced relationship between people and nature (e.g.

Encourage sustainable development). They permit the migration of a species when environmental conditions in a reserve deteriorate forcing them to move, corridors support animals that must make seasonal migrations to obtain food, enable species to shift their ranges if global climate change make their ranges uninhabitable. Helps to support more species and allows migrate by animals that need large ranges.
