PART3: write up
Earth had provided us with green land, pure water and fresh air. But after man wrong doing, earth started to change from good to bad, bad to worst and worst to even “more worst”. Earth will become hopeless if MAN continues to harm the environment. CAN WE SAVE THE ENVIRONMENT? NO NO NO! It is too late to start saving the earth now as MAN had already caused too much harm on the environment. The reports in “bbcnews” mention that chemical substances drastically pollute rivers and seas, the pollution was too severe that the costs of clearing are high and time taken would also be stretched. Pollution rate are too high that it had became irreversible, this cause the beautiful environment to fade away slowly. It is difficult for us to save the earth at such state where pollution were already existing at soaring level.

Next, Due to the growing population on earth, demand for land and natural resources are rising. Forests are clear for land and mining factory, this could cause extinction of certain species due to the lose of habitat. To meet the growing demand, more mining work are done causing more land to be abandon at it useless state. Soils harden and later became a manmade desert. Soil took years to recover naturally. How can we save the earth at this state??????

The introduction of advance technology into our environment had also provided negative effect to the earth. More machinery and vehicles means more fuel and petrol are needed; mining work increases hence, increasing the pace of destroying earth. Electrical waste pile up like a mountain in India and china as stated in “bbcnews” report, dangerous chemical in electrical appliances are expose to the environment. Improper disposal method allow hazardous chemical to seep through soil and into the rivers, it cause marine life to die and Human which consume these fishes will be poisoned. These electrical wastes could cause environmental degradation, hence destroying the earth. The only way to end the pollution is to stop manufacturing computers and electrical materials, BUT it is absolutely impossible for human to live on earth without computers and technology.

Being greedy and irresponsible, HUMAN always took everything for granted. Human action are the main causes for most pollution, not thinking of the consequences, human had harmed the environment severely. Improper waste management causes land pollution, oil and chemical leakage causes water pollution and harmful gases from factories or vehicles causes air pollution. Unless human could spare a thought for the earth, the earth then can be save. But it is IMPPOSSIBLE to unite the world as one. We can never save the environment.

Invention of fertilizers had increase farmers’ output hence, improving their standard of living. Fertilizer contain high amount of cadmium as stated in the bbcnews report. This chemical is detrimental and it could cause kidney failure. If cadmium is to seep through the ground and into rivers or seas, the marine live will be poisoned. Fertilizer is needed to improve the quality and quantity of crops to meet our daily demands. No fertilizers mean lesser food produce and lesser food production led to starvation. The consequences of not using fertilizers are heavier. Therefore, using of fertilizers cannot be bring to a halt. In this case, the environment is never going to be free from pollutions and THE EARTH COULD NOT BE SAVE!
Deforestation --> increase carbon dioxide in air --> temperature increases --> led to global warming!!! --> Disaster!
Land is limited on earth; hence, forests are all burnt down for land. This causes air pollution which increases the amount of greenhouse gases. Thus, causing global warming. Trees are needed for the manufacturing of papers. Can human stop using papers?? Global warming increases the rate of melting in the South and North Pole, this causes disaster such as flooding. How are we going to save the earth under such circumstances?

If our earth is not save in time, our future generation would suffer to a great extent. Disaster such as an increase in diseases, more land turning into desert, extinction of animals and decrease of oxygen in air etc… soon the world would come to an end.……

If our earth is not save in time, our future generation would suffer to a great extent. Disaster such as an increase in diseases, more land turning into desert, extinction of animals and decrease of oxygen in air etc… soon the world would come to an end.

Earth could not be save but we could always find alternative to prevent the earth from dying rapidly. For example, creating campaigns that explain the effect and consequences of pollution. Thus, bringing the citizen closer as one so together we could protect the earth from vanishing under such a fast rate. One should focus on the 3 Rs to help the environment, they are reduce, reuse and recycle.

Reducing the use fertilizer, papers and non-renewable materials could decrease the rate of pollution hence, helping the environment. Reducing the use of fertilizers would ensure the safety of consuming the fishes and vegetables, less trees would be cut down if uses of paper are reduce, using of non-renewable substances such as fuels have to be reduce as to lessen mining work. Recycling papers and can drinks would prevent environment from dying faster as less trees cut down and less metal from mining are use. Same for reusing of material, when things are being reuse, usage are lessen hence reducing the input. This again lengthens the earth lifespan. Cutting down one tree and growing back three trees or restocking the land which forest was once depleted with trees again, this is reforestation. Removing off a forest will affect the ecosystem that has the potential of causing harm to the environment. Lastly, the governments play a major role in leading their peoples to protecting the environment from being harm.

In conclusions, I believed that the environment couldn’t be save. =(

PART2: Synthesis

IS THE EARTH WORTH SAVING?? Yes, No, maybe??…
Yes because it is our home, No because others might not appreciate what you had done for the earth. Everyone had a part to play in saving the earth We always take for granted of what we had on earth and not thinking about the consequences, we had always damage the earth in one way and another. What is the purpose of saving the earth when it is already highly contaminated with pollution? A mercury leakage takes about 1 year to clean up and the cost for cleaning up is extremely expensive, mining had caused increasing rate of desertification, it is difficult to stop mining activities. All this proves that earth does not worth to be save. BUT saving the earth is equal to protecting our future. I conclude that earth should not be safe.
We want a green environment but not a dusty one.
Benefits of saving the earth for environment: trees and plants could grow healthily , no pollution to be found and animals were safe from deforestation.
Benefits of saving the earth for human health: diseases rate cause by pollution would decrease, human would have clean food to consume and human would not suffer from cancer or other illnesses.

BIGGEST threats
1.Human
2.Pollution
3.Technology
4.Toxic chemical
5.Improper waste management

The earth CAN’T be save and that is the fact. It is not a single person jobs to save the earth. One can’t protect the earth when everyone is destroying it at the other end. Simply say, it is impossible to unite everyone to save the earth. Natural resources would soon come to an end; as a result, people would live in open areas or inside cave. People would soon adapt to former farming system. As soil harden in time due to excessive amount of fertilizer added and improper agriculture system, land are now scarce which limit the area for farming. At this time, rate of pollution had already became perilous; people would be suffering from various diseases. Market selling raw meats and fishes will be seen everywhere. This would be our future prediction if we do not start protecting the earth now. SO WE MUST ALL DO OUR PART TO PROTECT THE EARTH NOW!

PART 1 (INVESTIGATION)

Environment is our home. Do we want to spend our time enjoying life on earth or suffering from pollution? OF COURSE IT’S ENJOYING but first we have to take good care of our environment. The environment could affect the planets and humans positively and negatively. From what I understand, when the environment is harm, the planet is likely to be affected too. For example, Deforestation causes the amount of Carbon Dioxide gas to increases, which then increase the temperature in air. In such cases, Flooding occur destroying animals habitat and human home.
Human, technology, chemical…. And many more… these are the sources that contribute greatly to affecting the environment. We humans are the masterminds to all the pollution we face today, environmental degradation occur when Man did not take good care of the environment. Technology and chemical are also part of the causes for environmental degradation. Examples from report in bbcNews mention that most pollutants in rivers are toxic and chemical, electrical waste contain chemical, which harm both human and environment. Environmental problem affect almost everything on earth, drinking water could be polluted, fisheries will be poison by chemicals, natural preserve could be destroy and animals may even became extinct. The eco system may be disrupted hence it will not work correctly, this cause changes to the environment and new adaptation for survival purpose will be introduce.
The environment is NOT healthy at all. There will always be pollution everyday. Report concluded that most pollution are man-made, it is compare to be irreversible because it take years to finish clearly up the pollution. Each time a computer was thrown away, it adds threat to the environment. Computers contain hazardous chemicals that are harmful to human and the environment.The threats to environment are humans while the biggest threat to environment are humans wrong doing. If most of us could spare a thought for the environment before doing anything, the earth would most likely be safe from danger. More campaign had to be introduce hence informing people the dangerous state we are living in.

Topic 15: Greenhouse effect

Impact on greenhouse Effect:
  • Drought
  • Forest-fires
  • Heatwave
  • Floods
  • Storms

It was a naturally-occurring phenonemon which helped us increase the temperature on earth, if temperature get too high, there will be much disaster occurring on the earth.

There are some man-made greenhouse gases such as Fluorocarbons or carbon dioxide, they had the ability to trap heat which warm the surface on earth.

TWO IMPORTANT greenhouse gases. ozone and halocarbon.

I believe that greenhouse gases are important to us, we need them to keep temperature constant. Exceeding limit of greenhouse gases will cause a lot of environmental problems. For example, Ice will melt in a faster rate causing flood and disaster for MAN.

Topic 14: Bhopal Gas tragedy

BOOM! A highly toxic poisonous gas release into the air, killing 2000 people instantly and injuring 300,000 people. Animals were also killed and hurt by the toxic cloud of methyl isocyanate. Those who survie the disaster were suffering from serious ailments such as blindness and impaired immune systems.

It destroy the tranquil atmosphere in the city of Bhopal, this is a worst scenario from a pollution.

Topic 13: Cadmium in fertilizers/peanuts: Oz

Consuming large amount of cadmium will likely to cause kidney damage, it was found in vegetables and meat. Australia New Zealand Food Auhority(ANZFA) had limit the amount of cadmium concentration in food so therefore to ensure that people will not take in the dangerous level of cadmium.
Cadmium are natural mineral which it accumulate in soils and was absorb into crops, the commission are trying to reduce the amount of cadmium in fertiliser, however, the EFMA believes that the climate and variability of soils will affect the accumulation of it in soils.

Technology are also invented to remove cadmium from phosphate rock or phosphoric acid before it was make into fertiliser.

It is our choice to increase cadmium or decrease it, our environment and health depend on us.

Topic 12: Mercury poisoning: Siberia

The mercury is an extremely hazardous chemical, it could damage our internal organs or even causing us to have personality changes. A small amount of mercury could simply destroy the human nervous system, these 1,500 tonnes which seeped into the soil and then into rivers could wipe out the whole population. Drastically harmful and dangerous, the mercury should be clean up quickly to prevent any further critical problem. However, cleaning efforts are slow and it take 1000 years to finish clearing up at this pace.

Mercury cause:

  • Headaches
  • Respiratory and intestinal diesease
  • Hand tremors
  • Damaging central nervous system and kidneys

Mercury pollution causes serious harm to the environment, it destroy habitat of marine animals, pollute the air and causing man to live with FEAR.
