the result...

finally i finish my assign and had submitted it. this is the result..

how i make it?

i'm just using pentool and and pencil to draw this image in illustrator. i put the original image and trace from there. for the dotted in the petals, i'm using convert anchor point tool to edit the shape. for the corn in the middle, i'm also using pentool and make it one by one. the red n orange color i chose is based on original image and i play with gradient to make it more realistic.

rafflesia

i finish up my assign 2 and come out with the suggestion idea which is rafflesia..
this is the reference image that i used in completing this assignment

tomorrow i will see mdm ling to show my work to her if she have any comment. if she accept and agree with my work i will update again by posting the illustrator file

deforestation...

wow it's been a long time i havent update this blog after mid term break. i just finish doing research for deforestation issues to relate it for my assignment 2 task. this is what i got from internet..

Deforestation is the conversion of forested areas to non-forest land for use such as arable land, pasture, urban use, logged area, or wasteland. Generally, the removal or destruction of significant areas of forest cover has resulted in a degraded environment with reduced biodiversity. In many countries, massive deforestation is ongoing and is shaping climate and geography. Deforestation results from removal of trees without sufficient reforestation, and results in declines in habitat and biodiversity, wood for fuel and industrial use, and quality of life.

Impact on the environment

Generally, the removal or destruction of significant areas of forest cover has resulted in a degraded environment with reduced biodiversity. In many countries, massive deforestation is ongoing and is shaping climate and geography.

Deforestation is a substantial contributor to global warming,[ and although 70% of the oxygen we breathe comes from the photosynthesis of marine green algae and cyanobacteria, the mass destroying of the worlds rain forests is not beneficial to our environment. In addition, the incineration and burning of forest plants in order to clear land releases tonnes of CO2 which increases the impact of global warming.

Deforestation reduces the content of water in the soil and groundwater as well as atmospheric moisture. Deforestation reduces soil cohesion, so that erosion, flooding and landslides often ensue. Forests support considerable biodiversity, providing valuable habitat for wildlife; moreover, forests foster medicinal conservation and the recharge of aquifers. With forest biotopes being a major, irreplaceable source of new drugs (like taxol), deforestation can destroy genetic variations (such as crop resistance) irretrievably.

Shrinking forest cover lessens the landscape's capacity to intercept, retain and transport precipitation. Instead of trapping precipitation, which then percolates to groundwater systems, deforested areas become sources of surface water runoff, which moves much faster than subsurface flows. That quicker transport of surface water can translate into flash flooding and more localized floods than would occur with the forest cover. Deforestation also contributes to decreased evapotranspiration, which lessens atmospheric moisture which in some cases affects precipitation levels down wind from the deforested area, as water is not recycled to downwind forests, but is lost in runoff and returns directly to the oceans. According to one preliminary study, in deforested north and northwest China, the average annual precipitation decreased by one third between the 1950s and the 1980s.

Longterm gains can be obtained by managing forest lands sustainable to maintain both forest cover and provide a biodegradable renewable resource. Forests are also important stores of organic carbon, and forests can extract carbon dioxide and pollutants from the air, thus contributing to biosphere stability. Deforestation (mainly in tropical areas) account for up to one-third of total anthropogenic carbon dioxide emissions.Forests are also valued for their aesthetic beauty and as a cultural resource and tourist attraction.

“Reducing emissions from tropical deforestation and forest degradation (REDD) in developing countries has emerged as new potential to complement ongoing climate policies. The idea consists in providing financial compensations for the reduction of greenhouse gas (GHG) emissions from deforestation and forest degradation”.
