Gentically Modify Food




Genetically Modified Food also known as "GM Food" are products that their DNA had been altered through genetic engineer. Unlike other genetically modified system that are time-tested to ensure their safety, this product were introduce in the early 1990s. One of the most Modified "GM Foods" are soybean, cotton seed oil, corn and canola.

One of the most know controversies is their easy reach for the average individual for consumption, and the healthy issues develop after the years of consuming these products. The endanger of braking the natural food chain, therefore government and big corporations claim that is the boom of the human race, while healthy-conscious people believe it to be a potential disaster.

List of the genetically modified foods "GM Food";

Lettuce
Orange Juice
Bread
Cereal
candy
Straw berry

California Condor






The California Condor (Gymnogyps californianus)
A mebmer of the Cathartidae. Thi Condor only habitas the Baja California, The Grand Canyon on the western area coastal mountains of north California. Althoug some fossil mebers are found, it is the only member alive of the genus Gymnogyps.
A big bird almost 9ft on wing span when adult, black vuture wiht patches of white on yhe underside. A large bald head with color rangin form yellowish to a bright red depending of the condor's mood. it posses one of the heviest wihgspan in North-America. The condor is a scavanger and has one of the longest life span of any bird ranging to 50 years of age.

The numbver decrease dramatically due to the poaching, led poisoning, and habitat destruction. The gorverment try to preserve this bird wiht a plan of capturing the remaining wild condors in 1987. At that time there were only 22, San Diego Animal Park and the Los Angele Zoo, ketp them in captivity and their numbers rose, and in 1991 were reintorduced to the wild. The conservation proyect was one of the most expensive for animal control in the United States. As of today 332 condros are known to live including 156 that are in the wild.

The condor use to play an importan role for Native Americans due that they were symbolic to them. Overall this condor average from 117-135 centimeters (45-53ft), it has a wing span of 2.77meters (9.1ft), their weight range is form 7-14 kilograms (15-31lb), or 8-9 kilograms (18-20ft), on flight it its estimated that the caondors can flight arround 90Kmph(55mph) and a ceiling of 4,600meters (15,000ft).

The diet of this condors is mostly small to large mamalian such deer, goats, sheep, donkeys, horses, pigs, moutain lions, bears, and cattle. Aquatic animals such, salmon, whales, andsea lions. The condor can cover an ares of 250 kilometers (150 miles), a day in search of the animals previusly mentioned.

Carbon Cycle







The Carbon Cycle

















Carbon Cycles is one of the most important for the Erhart's stability and maintenance. It is found in the atmosphere, on vegetation, the ocean , and beneath the earths ground also as known fossil fuels.

In the atmosphere carbon coexist as a gas (CO2) but in smaller amounts (approx .04% on a molar basis, and basis). It plays an important rule of maintaining life. Other carbon gasses are found such methane, and chlorofluorocarbons. These two previous mention gases are also called green gases and they are growing in large quantities creating the issue of global warming. Carbon is taken from the atmosphere in different ways.

As the sun shines the plants convert the carbon into oxygen thanks to the photosynthesis creating carbohydrates realising the oxygen into the air.
Forest hold 86% on the earth's carbon-atmosphere, and 73% of the planet's soil carbon.

Carbon is released in many ways; the respiration made by plants and animals, through decay, by fungi and bacteria break down, through combustion, fossil fuels such; petroleum, natural gas, production of cement when heating limestone carbon is released and create lime a component of cement, and by volcanic eruptions, water vapors and sulfur dioxide.

In the Biosphere Autotrophs produce their own organic compounds using CO2 from air or water in which they live. To perform these task they would need an source of energy, generally all Autotrophs get the energy from the sun and this process is call photosynthesis. On land the process is made by trees and in water by phytoplankton.

In the Ocean the presence of carbon is about 36,000 gigatones manly bicarbonate ion.
Extreme storms such hurrinaces and typhoons bury a lot of carbon because they wash away the sediment. A study made in Taiwan conclude that a single typhoon can collect large quantities of carbon , more that the single rains that can happen in that country combine in one year.

Inorganic carbons also play an important role when they are combine with carbon-carbon or carbon-hydrogen bonds. this carbon exchange is crucial for determine the PH of the oceans water.

Carbon is essential for our environment but it can be dangerous if not properly managed. All organinc and inorganic species relay on carbon for their existance, as human kind it is necesary to controll their usage and disposal.

Geenpeace

Greenpeace, fulfill my expectations of real observation of the poles and underline the real problem that man kind encounters today which is "Global Warming".



As a foundation it is noticeable that all their member really appreciate the value of controlling the environment, and do not care about risking their own lives in other to stop all the unfairness done by many of the big corporations. Green peace has their own identity, the small boat and their lonely members trying to overcome big corporation objectives of getting their profits without caring of the environment or harming endanger species.

As a person who cares of the evironment and wants to overcome the bad desition making of how to use our natural resources, the best option for me would be "Greepeace".
