Banksia

Banksia is a genus of approximately 80 species in the plant family Proteaceae. They are native to Australia, taking place in all but the most arid areas. Simply recognized by their characteristic flower spikes and fruiting "cones", Banksia are a well-known Australian wildflower and a well-liked garden plant. They grow up in forms varying from prostrate woody bushes to trees up to 25 metres tall. They are normally known as Banksias or Australian Honeysuckle Trees.

Banksias develop as trees or woody shrubs. The biggest trees, the Coast Banksia, B. integrifolia, and the River Banksia, B. seminuda, often grow over 15 metres tall, and may be up to 25 metres tall. Banksia species that raise as shrubs are usually erect, but there are several species that are prostrate, with branches that grow on or below the soil.

Prevention

In medicine, prevention is any action which reduces the burden of humanity or morbidity from illness. This takes place at primary, secondary and tertiary prevention levels.

Primary prevention avoids the growth of a disease. Most population-based health support actions are primary preventive measures.Secondary prevention activities are intended at early disease detection, thereby increasing opportunities for interventions to prevent progression of the disease and emergence of symptoms.Tertiary prevention reduces the negative impact of an already recognized disease by restoring function and dipping disease-related complications.

Sugarcane

Sugarcane or Sugar cane (Saccharum) is a genre of between 6–37 species (depending on taxonomic interpretation) of tall grasses (family Poaceae, tribe Andropogoneae), native to warm temperate to steamy regions of the Old World. They have heavy, jointed fibrous stalks 2–6 m tall and sap rich in sugar. All the species interbreed, and the major commercial cultivars are complex hybrids.

Saccharum officinarum grown-up in Hawaii.There are 13 million hectares (32 million acres) of sugar cane plantations worldwide, with over 100 countries growing the crop. The peak twenty producing countries harvested 1200 million metric tons of sugar cane in 2002 , more than 6 times the amount of sugar beet produced. The major producers are Brazil, India, and China..
