Wheat shortage in the world caused is climate change.
I think is this goes on we will not be able to have enough rice to supply us fir life.
We must take care of your own home earth. We should stops global warming by recycling, reusing and reducing. Droughts caused by global climate change have led to a drop in wheat production, a worldwide shortage and high food prices around the world.The global wheat supply is at its lowest point in 50 years, with only an estimated 10 weeks of supply left. This has been one factor pushing the prices of bread, beer and other wheat-containing foods steadily higher
Also to blame for the global wheat shortage is rising population, coupled with increasing meat consumption worldwide. This has led to the increasing diversion of grain to animal feed. Analysts anticipate that the shortage may be resolved within 12 months, as farmers pull fallow land into wheat production. But even when the shortage resolves, food prices are only expected to keep climbing due to other factors, such as high energy and shipping cost.

carbon in the air
3rd march 2009
Carbon in the air.
Atmospheric carbon dioxide has increased from around 280 parts per million (by volume) in 1800 to around 315 in 1958 and 380 in 2005, a 31% increase over 200 years (IPCC, 2001). Other greenhouse gas emissions have also increased. Future carbon dioxide levels are expected to rise due to ongoing economic development dependent on fossil fuel usage, though the actual trend for the future will depend on economic, sociological, technological, and natural developments. The Intergovernmental Panel on Climate Change has concluded that there will be both global and regional climatic change, altered precipitation patterns, occurrence of extreme events such as droughts and hurricanes and an increase in climate variability (Houghton et al., 2001) during the next 100 years (IPCC, 1995, 2001). According to ice core climate record, today’s rising atmospheric carbon dioxide concentration, at 380 parts per million by volume, is 27 % higher than its highest recorded level during the last 650,000 years (Brook, 2005).

Climate change .
UP TO one-third of all Antarctic sea ice is likely to melt by the end of the century, seriously contributing to dangerous sea level rises, updated scientific modelling on global warming shows.The modelling is the first release of a landmark study being conducted by the global scientific body the Scientific Committee on Antarctic Research, made up of the peak scientific bodies from 23 countries including Australia. The early numbers put out by SCAR suggests the collapse of Antarctic sea-ice not only pushes up anticipated sea level rises but will threaten the numbers of native animal species including emperor penguins, humpback whales and several fish species.The initial release of research also suggests sea temperatures in the Southern Ocean are rising faster than in other oceans, and that ice melts in the Antarctic Peninsula and Western Ice Shelf will be greater and more rapid than expected.Responding to the release of the executive summary of the SCAR report, the WWF manager for Antarctic and Southern Oceans Initiative, Rob Nicoll, said the evidence was showing how quickly the effects of global warming were showing up in the Antarctic region. Ice shelves the size of small countries are crumbling away and the latest evidence from the Antarctic is showing that the effects of lobagl warming there are increasing in magnitude.

CHEK JAWA virtual tour(Mahkes and Mithi)
Chek Jawa
At first, we thought that Chek Jawa was in some part of Indonesia. But it actually is in Pulau Ubin! Chek Jawa is a gem of marine wildlife. Located at the eastern tip of Pulau Ubin, Chek Jawa is a collection of six distinct habitats - coastal forest, mangroves, sand bars, sea grass lagoon, rocky shore & coral rubble. Some of these habitats can be found at Pulau Sekudu, which is considered part of Chek Jawa We have learnt that Chek Jawa has a wide variety of exotic animal. Chek Jawa is teeming with a wide array of marine wildlife – starfish, sea horses and octopi living in the sand and mud flats, carpet and peacock anemones in the sea-grass meadows, and sponges of all hues residing in the coral rubble.

One of the fascinating animals would be the sea pen long, slender colonial organism of the same phylum as the jellyfish. Sea pen colonies are formed by several genera of the order Pennatulacea. The colony consists of a stalk formed by an organism called a primary polyp (see polyp and medusa) and short branches formed by secondary polyps. The stalk, embedded in sand or mud, holds the colony upright. Sea pens differ from the closely related sea pansies and sea feathers by the form of the colony. Sea pens are .marine organisms; they are found on Atlantic and Pacific coasts in shallow to moderately deep water. Some reach a length of 2 ft (61 cm) or more. They belong in the phylum Cnidaria, class Anthozoa, order Pennatulacea.
The sponges or poriferans bodies consist of an outer thin layer of cells, the pinacoderm and an inner mass of cells and skeletal elements, the choanoderm. Sponges do not have nervous, digestive or circulatory systems. Instead most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, and the shapes of their bodies are adapted to maximize the efficiency of the water flow. All are sessile aquatic animals and, although there are freshwater species, the great majority are marine (salt water) species, ranging from tidal zones to depths exceeding 8,800 metres (5.5 mi). While most of the approximately 9,000 known species of sponge that live in food-poor environments have become carnivores that prey mainly on small crustaceans.
We have learnt that Chek Jawa is a precious place and it is one of the few nature reserves in Singapore which has a variety of many exotic animals that we should cherish and preserve so that the future generation can enjoy the array of animals that we have for them.

Growth Day
During growth day we set our target according to our last year grades and emphasize on our new school theme “beyond bridging gaps”. And we are also needed to make a 30 second video. My class did a video about explaining things better. Then after that we all went to the hall and all our videos were showed in the hall
