Open ocean

The great expanse of open ocean habitat is huge, and many species can be found passing through it and living in it. The term "open ocean" usually is meant to refer to the vast stretches of water between points of land, or between undersea mounts. Contrary to popular notions the open ocean is often not the place where marine animals spend the majority of their lives. Most species simply pass through the open ocean on their ways to other places. Larger species are the main ongoing inhabitants.

Bodhi Tree

The Bodhi Tree, also known as Bo (from the Sinhalese Bo), was a large and very old Sacred Fig tree (Ficus religiosa) located in Bodh Gaya (about 100 km/62 mi from Patna in the Indian state of Bihar), under which Siddhartha Gautama, the spiritual teacher and founder of Buddhism later known as Gautama Buddha, achieved enlightenment, or Bodhi. In religious iconography, the Bodhi tree is recognizable by its heart-shaped leaves, which are usually prominently displayed.

The term "Bodhi tree" is also widely applied to currently existing trees, particularly the Sacred Fig growing at the Mahabodhi Temple, which is probably a direct descendant of the original specimen. This tree is a frequent destination for pilgrims, being the most important of the four holy sites for Buddhists. Other holy Bodhi trees which have a great significance in the history of Buddhism are the Anandabodhi tree in Sravasti and the Bodhi tree in Anuradhapura. Both are believed to have been propagated from the original Bodhi tree.

Adansonia

Baobab is the common name of a genus (Adansonia) containing eight species of trees, native to Madagascar (having six species), mainland Africa and Australia (one species in each). The mainland African species also occurs on Madagascar, but it is not a native of that country.

Other common names include boab, boaboa, bottle tree, upside-down tree, and monkey bread tree. The species reach heights of 5 to 30 metres (16 to 98 ft) and trunk diameters of 7 to 11 metres (23 to 36 ft). An African Baobab specimen in Limpopo Province, South Africa, often considered the largest example alive, has a circumference of 47 metres (150 ft) and an average diameter of 15 metres (49 ft).

Some baobabs are reputed to be many thousands of years old, which is difficult to verify as the wood does not produce annual growth rings, though radiocarbon dating may be able to provide age data.

The Malagasy species are important components of the Madagascar dry deciduous forests. Within that biome, A. madagascariensis and A. rubrostipa occur specifically in the Anjajavy Forest, sometimes growing out of the tsingy limestone itself.

Beginning in 2008, there has been increasing interest for developing baobab as a nutrient-rich raw material for consumer products.

Hemp

Hemp (from Old English hænep, see cannabis (etymology)) is the common name for plants of the entire genus Cannabis, although the term is often used to refer only to Cannabis strains cultivated for industrial (non-drug) use.

Industrial hemp has many uses, including paper, textiles, biodegradable plastics, health food, and fuel. It is one of the fastest growing biomasses known,[citation needed] and one of the earliest domesticated plants known. It also runs parallel with the "Green Future" objectives that are becoming increasingly popular. Hemp requires little to no pesticides, no herbicides, controls erosion of the topsoil, and produces oxygen. Furthermore, hemp can be used to replace many potentially harmful products, such as tree paper (the processing of which uses bleaches and other toxic chemicals, and contributes to deforestation), cosmetics, and plastics, most of which are petroleum-based and do not decompose easily.

Cannabis sativa L. subsp. sativa var. sativa is the variety grown for industrial use in Europe, Canada, and elsewhere, while C. sativa subsp. indica generally has poor fiber quality and is primarily used for production of recreational and medicinal drugs. The major difference between the two types of plants is the appearance and the amount of Δ9-tetrahydrocannabinol (THC) secreted in a resinous mixture by epidermal hairs called glandular trichomes. Strains of Cannabis approved for industrial hemp production produce only minute amounts of this psychoactive drug, not enough for any physical or psychological effects. Typically, Hemp contains below 0.3% THC, while Cannabis grown for marijuana can contain anywhere from 6 or 7 % to 20% or even more.

Beaverhead crater

Beaverhead is an impact structure in central Idaho and western Montana in the United States.Estimated at 37 miles in diameter (60 km), it is one of the largest impact craters on Earth. Its age is estimated to be about 600 million years (early Neoproterozoic).

The structure is named after the area in southwest Montana where evidence of an impact was first discovered in 1990. Other than the original shatter cones found on the perimeter, there is little visible evidence of the structure.
