A forest is an area with a high bulk of trees. There are several definitions of a forest, based on a variety of criteria. These plant communities face large areas of the globe and function as animal habitats, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. While frequently thought of as carbon dioxide sinks, grown-up forests are approximately carbon neutral with only troubled and young forests acting as carbon sinks. However mature forests do play a main role in the global carbon cycle as stable carbon pools, and authorization of forests leads to an increase of impressive carbon dioxide levels.

Forests sometimes have many tree species within a small area or comparatively few species over large areas. Forests are frequently home to many animal and plant species, and biomass per unit area is high compared to other plants communities. Much of this biomass occurs below-ground in the origin systems and as partly decomposed plant accumulation. The woody element of a forest contains lignin, which is comparatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.

Technology is a large concept that deals with a species' procedure and information of tools and crafts, and how it affects a group' capability to control and get used to its environment. In human culture, it is an importance of science and engineering, although several technical advances predate the two concepts

Technology has affected society and its environment in a number of ways. In many societies, technology has helped increase more advanced economies and has allowed the rise of a spare time class. Yet, many technological processes create unwanted by-product, known as pollution, and reduce natural resources, to the detriment of the Earth and its environment. Various implementations of technology control the values of a society and new technology raises new moral questions. Examples include the rise of the concept of effectiveness in terms of human productivity, a term originally useful only to machines, and the challenge of traditional norms.

Education System

Schooling occurs when group or a society or an individual sets up a curriculum to educate people, usually the young. Schooling can become systematic. Sometimes education systems can be used to promote doctrine or ethics as well as knowledge, and this can lead to abuse of the system.

Life-long or adult education have become extensive in many countries. However, education is still seen by many as something aimed at children, and adult education is often branded as adult learning or ultimate learning.

Adult education takes on several forms, from formal class-based learning to self-directed learning. Lending libraries provide cheap informal access to books and other self-instructional materials. Many adults have also taken advantage of the rise in computer ownership and internet access to further their casual education
