Biofuel: Tomorrow´s Fuel
Biofuel can be broadly defined as solid, liquid, or gas fuel consisting of, or derived from biomass. The definition used here is narrower: biofuel is defined as liquid or gas transportation fuel derived from biomass. Biomass can also be used directly for heating or power. One type of biomass is wood, which is [...]
Why don´t you choose an Organic Fertilizer?
Fertilizers typically provide, in varying proportions, the three major plant nutrients (nitrogen, phosphorus, and potassium), the secondary plant nutrients (calcium,sulfur,magnesium), and sometimes trace elements (or micronutrients) with a role in plant nutrition: boron,chlorine,manganeso,iron,zinc ,etc).
In the past, both organic and inorganic fertilizers were called “manures” derived from the French [...]
Eucalyptus
A large and important genus of Australian forest trees; includes about 500 species in the family Myrtaceae. Only two species occur naturally outside Australia in the adjacent islands. Eucalypts occur throughout Australia except in coastal tropical and subtropical rainforests in Queensland and New South Wales and in temperate rainforests in Victoria and Tasmania. They are [...]
When should I water my orchids?
When to water will vary based on type of orchid and what the conditions are. Over watering is probably the major cause of orchid death with new growers.
The best thing is to develop a method of knowing when to water. Some people go by “heft.” Lift the pot right after [...]
Orchids are easily distinguished, as they share some very evident apomorphies. Among these: bilaterally symmetric (zygomorphic) and resupinate, a petal (labellum) is always highly modified, stamens and carpels are fused and the seeds are extremely small.
Orchids belong to the most diverse family of plants known to man. There are over 880 genera, 28,000 species and [...]
Deforestation:
Deforestation is the permanent destruction of indigenous forests and woodlands. The term does not include the removal of industrial forests such as plantations of gums or pines. Deforestation has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area. Indigenous forests now cover 21% of the earth’s land surface.
Generally, the removal or [...]
Climate change refers to the variation in Earth’s global climate or in regional climates over time. It describes changes in the variability or average state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes internal to the Earth, external forces (e.g. variations in sunlight [...]

Summary: Fatal flaws in the recent report from Badgley et al. claiming that organic agriculture “could produce enough food on a global per capita basis to sustain the current human population, and potentially an even larger population, without increasing the agricultural land base.” Among [...]
Sept. 6, 2007 — Summertime sea ice in the Arctic Ocean is on track for shrinking by 40 percent below 1980 and 1990 levels by the year 2050, say oceanographers. That’s twice as fast as the rate of loss estimated in the most recent assessment by the Intergovernmental Panel on Climate Change (IPCC).
“This (is) a [...]
The word “biotechnology” simply means using living organisms, or parts of them, to provide goods or services. Foodstuffs made from plants bred using genetic engineering are already being sold in parts of the world and they are, in general, not different to the foods we already eat. A genetically modified organism is defined as an [...]
