AT school we have been making eco footprints to cut out and make some goals that we are going to try to achive them in the next few weeks so far I have achived 2/3
1)Using reuseable things like E.G: -snaplock bags - reuseable shoping bags (complete)
2)Biking to school every day to try and reduce the time I spend in the car (complete)
3)persuad my parents to buy and use suatainable products

The Hindenburg disaster took place on 6 May 1937 as the German rigid airship Hindenburg caught fire and was destroyed within one minute while attempting to dock with its mooring mast at the Lakehurst Naval Air Station, which is located adjacent to the borough of Lakehurst in Manchester Township, New Jersey. Of the 97 people on board, 35 people died in addition to one fatality on the ground. The disaster was the subject of spectacular newsreel coverage, photographs, and Herbert Morrison's recorded radio eyewitness report from the landing field, which was broadcast the next day. The actual cause of the fire remains unknown, although a variety of theories have been put forward for both the cause of ignition and the initial fuel for the ensuing fire.
The disaster drove people away from hydrogen airships and is still said that it was one of the worst hydrogen disasters ever recorded.

On Tuesday 2ND June 2009 Some students from SIFE At the university of Waikao It was a very interesting session. Some of the things they talked about were to do with how we effect the globe and how we can do beter to try to protect it. these are some of the notes I recorded:(1) Sustainability has become a complex term that can be applied to almost every system on Earth, particularly the many different levels of biological organization, such as; wetlands, prairies and forests and is expressed in human organization concepts, such as; eco-municipalities, sustainable cities, and human activities and disciplines, such as; sustainable agriculture, sustainable architecture and renewable energy. (2)For humans to live sustainably, the Earth's resources must be used at a rate at which they can be replenished. However, there is now clear scientific evidence that humanity is living unsustainably, and that an unprecedented collective effort is needed to return human use of natural resources to within sustainable limits. They also did some amazing stuf about how we could through out 1/2 of the rubish we could usally throw away WOW!!!!!!!!!!!

The Earth is unevenly heated by the sun resulting in the poles receiving less energy from the sun than the equator does. Also, the dry land heats up (and cools down) more quickly than the seas do. The differential heating drives a global atmospheric convection system reaching from the Earth's surface to the stratosphere which acts as a virtual ceiling. Most of the energy stored in these wind movements can be found at high altitudes where continuous wind speeds of over 160 km/h (100 mph) occur. Eventually, the wind energy is converted through friction into diffuse heat throughout the Earth's surface and the atmosphere.Humans have been using wind power for at least 5,500 years to propel sailboats and sailing ships, and architects have used wind-driven natural ventilation in buildings since similarly ancient times. The use of wind to provide mechanical power came somewhat later in antiquity.
The Babylonian emperor Hammurabi planned to use wind power for his ambitious irrigation project in the 17th century BC. The ancient Sinhalese utilized the monsoon winds to power furnaces as early as 300 BC evidence has been found in cities such as Anuradhapura and in other cities around Sri Lanka The furnaces were constructed on the path of the monsoon winds to exploit the wind power, to bring the temperatures inside up to 1100-1200 Celsius. An early historical reference to a rudimentary windmill was used to power an organ in the 1st century AD. The first practical windmills were later built in Sistan, Afghanistan, from the 7th century. These were vertical-axle windmills, which had long vertical driveshafts with rectangle shaped blades. Made of six to twelve sails covered in reed matting or cloth material, these windmills were used to grind corn and draw up water, and were used in the gristmilling and sugarcane industries. Horizontal-axle windmills were later used extensively in Northwestern Europe to grind flour beginning in the 1180s, and many Dutch windmills still exist.

Today we are studying economics and haw the market works. The Practical uses of supply and demand analysis often center on the different variables that change equilibrium price and quantity, represented as shifts in the respective curves. Comparative statics of such a shift traces the effects from the initial equilibrium to the new equilibrium.
When consumers increase the quantity demanded at a given price, it is referred to as an increase in demand.

Hi everybody it's bobby here did you know that an internationally renowned energy expert believes New Zealand could generate all its electricity from renewable sources within twenty years. Wow!!!!!!!!
Eco House are built in such a way that reduces energy consumption and waste. Eco Houses reduce the buildings bad impact on human health and the environment, through better design, construction, siting, operation and maintenance. Eco Houses are a combination of sustainable design, sustainable development and sustainable living. Eco houses are designed and built as part of the larger ecology of the planet; the design and construction of the building are done in harmony with the natural environment. Studies have shown that buildings are the most damaging polluters on the planet, consuming over half of all the energy used in developed countries and producing over half of all the climate-changing greenhouse gases. A successful eco house should give the owner the ‘best of both’ by providing less of an impact on the environment along with a healthier place to live and lower ongoing running costs. Eco Bob
Personly I go for Eco. On the Matai island I will stay eco and try to keep it going through my family.

Our Class is pretending that we have a imaginary island and we are trying to see what jobs we could take up if we were living on the island I think that I would be good at:
-an assistant mayor or maybe on the Island council because of my great leadership skills
-maybe a advertiser because I am quite a persuasive person
thanks for all the time you have taken to read this
Uranium is one of the ingredients needed in nuclear weapons, power and other things that nuclear stuff supplies. Say we found a island with nothing on it but forest and then we get there to find that it is covered in uranium (well under neath the ground) and we can't decide what to do with it. Maybe mine it and sell it for $44.00 a pound or just use it for our selfs. I personally don't like to be selfish so I would go for no.1 but then is it worth it.
To all that are reading this, I urge that we all try to protect the earth by:
- reducing reusing and recycling and not filling up the land fills.
-stop using the amount of power we use because power stations effect global warming the most. (check the post above)
-and start to use wind power or other related and good for the environment

This is a pie graph of how we effect Global Warming. Waste disposal and treatment got a good 3.4%, land use and biomass burning got 10.0%, residential, commercial,and other sources got an average 10.3 %, fossil fuel retrieval, processing and distribution got a bit higher with 11.3%, agricultural byproducts with a bit of a change 12.5%, transportation fuels another decent change 14.0% industrial processes with 16.8%, power stations gets the worst with 21.3% now to the green house effect the reason global warming is happening is because the suns rays (a combination of heat and light) gets through the the top of the atmosphere hits the earth and then can't escape this is making the poles melt and the sea level rise.
