How Paper Was Invented?


"Paper wasp" using pieces of wood to form paper to build their nest.
Paper is one of the important inventions that make the development of human knowledge growing even faster. Although the paper used for various purposes, the main usage of paper such as for writing, recording and storing information are the most important usage of paper. Although paper is used by humans but it also had been used by nature (by insects) since millions of years ago.

Insects known as paper wasps or also known as “angkut-angkut” (in Malay) are the real designer of paper. This insect can be found almost all over the world with the number of species up to more than 1,100 species in total. But all these insects build their nests using paper produced using fiber from trees or plants which are then mixed with saliva to form a nest.

Cai Lun, who invented paper making methods.
The uniqueness of this insect was observed by an official Chinese government called Cai Lun (Traditional Chinese : 蔡倫). Cai Lun said to be inspired by his observation of the insects’ paper wasp that build their nests from wood fiber use in about 105 AD. Although the paper production process continues to be improved but retained the original process by collecting a layer of plant fibers suspended in water using a strainer to separate the water before it is dried. It is through this discovery, he was known as one of the key figures with various awards.

Traditional production process of paper.
Paper production technique is expanding to other regions of China to the Middle East and to some parts of Europe. Paper development in the West is through Baghdad and it is known as “bagdatikos”. Since paper is an important material, paper-related industries continue to be developed either in terms of the materials used, as well as its own production process. Even paper recycling technologies are being introduced since 1774 by a jury from German, Justus Claproth.

While paper commonly used to keep a record or to print, it is also used for a variety of other usage such as packaging, boxes, building walls, as handicrafts, food containers, paper and more.

However, reducing paper consumption can safe lots of trees and other plants as a source of fiber (cellulose) where demand for paper continues to grow each year. Today with the advancement of digital technology, the demand for paper had been decreased, but still necessary. In terms of the paper pollution anyway, it's not as bad as the impact of plastic pollution, but if not controlled, it can also lead to negative impacts.


Anyway paper is one of the results that we get from the observations made on nature. For insects "paper wasp" paper has been used by them for millions of years for the purpose of building their nest. Hopefully, we will always be more sensitive to see how to utilize natural resources available in nature itself, but at the same time not damaging it.

Unique Group of Plants; Cactus


Cactus has important functions and is a unique plant.
For those of us who live in the tropics cactus may seem unusual because it grows in dry areas. Although some can be grown here, but the cacti are group of plants that so large just as other plants group.

Cactus plants are collection of plants in the family Cactaceae, the group consists of 127 genera and consists of approximately 1,750 species identified. It has varieties in sizes and shapes with a relatively wide distribution, but usually in a dry lying area (with low rainfall levels). However, some families of cactus is very unique and a plant that supplies tasty fruit to be eaten.

Cactus is an important source of food in the desert.
Just like any other plants cactus conducting photosynthesis to produce its own food. The different is most cacti equipped with spikes coming out of the trunk through the points known as "areola". The thorns on cactus also vary according to the type (and it is one of the important features to recognize a species of cactus).

Although cacti spines provide protection to the cactus it also has many other purposes. One is to reduce the sunlight directly hit on the stem. Spines also offer little protection from the hot sun. Even for species of cactus "cholla", spines help to spread the seeds that will be attached to the animal and will fall in a new place that might be appropriate for it to grow on more fertile land.

However cacti are also an important plant to animals and humans. For examples animals such as desert tortoises, cactus is a source of food that can provide energy and water, while other animals are also made of cacti as place to build nest and home. At the same time, human take benefit of cacti as a source of water when necessary. While some species of cacti produce edible fruit. Among the most famous cactus fruit is "dragon fruit". Even for "dragon fruit", the entire part of the plant can be used to provide food source for humans.

Cholla cactus has spines that easily attaches.

Few other species of cacti used as decoration.
Among the interesting things about the cactus is; the largest cactus is from the species of Pachycereus pringlei, ever recorded reached a height of 19.2 m (63 ft), while the smallest species are   Blossfeldia liliputiana, with the diameter size of only 1 cm (0.4 in) when mature. While such a large species of cactus "saguaro" (Carnegiea gigantea) is said to be able to absorb water up to 200 US gallons (760 liters) during the rainy season.


Recognizing the uniqueness of these cacti, many cactus centers been opened to get people attention and educate the important of cacti. It also featured as an ornamental plant, many more potential cacti raised here. Naturally cactus is a plant that is still less explored for its further potentials. Then recognizing these unique plants and learning more about it are very important.
