We feel that this activity has greatly increased our knowledge about pollution. It now makes us more conscience about our actions so that it would not damage the environment. Although it may not seem like a serious problem in singapore, other countries like china are facing it and we should learn from foreign examples to keep our land clean and green
Through this project, we have learnt that air pollution not only occurs outdoors but It can also occur indoors. In fact poorly ventilated houses can be over 60 times more polluted than the outdoors. I learnt that there can be many sources of pollution indoors, such as wooden stoves and many others. We learnt the many sources of air pollution in the process of researching, air pollution sources are not man-made, and there are natural sources that may give out much more air pollutants than the factories. A volcano eruption can release tons of ash into the sky, blocking out the sun sometimes for months, toxic substances are also released into the environment. This has been a link to our science; we learnt how humans can disrupt the carbon cycle and therefore result in global warming which we are experiencing now. We have also learnt how serious the effects of air pollution can be to the environment and humans. Some toxic substances can actually break down the waxy surface of the plants thus making absorb too much water. Air pollution causes 5billion worth of lost in crops a year. It also causes 2.4 million people to die each year.
