According to O'Sullivan(2016), if the population is over 30 million, the food-secure could not be guaranteed and the irrigated foods would reduce as most Australian city relying on sea water desalination. This means that the contradiction between large population and food shortage would become worse.]]> 2018-02-23 02:00:46 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234552732 https://padlet.com/karen_fong/qsah6p3usdja/wish/234552782 Another reason for not increasing population is that it may cause a series of resource problems. According to O' Sullivan(2016), Australia, which is a dry continent with water shortage and fragile land, may not be maintained food- supplying in drought years and it may affect over 30 million people. As a result, most of Australia's capital cities are relying on desalination for water security in droughts and decreasing exports of irrigated crops.]]> 2018-02-23 02:01:07 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234552782 https://padlet.com/karen_fong/qsah6p3usdja/wish/234552824 Monica+Cynthia
Another reason for not increasing population is that it might cause resource shortage. This is because a larger population requires more natural resource which may not afford enough food supply in drought years . According to O’Sullivan (2016) , most big Australian cities are lack of freshwater and irrigated crops. For these reasons, local government should not increase population dramatically to ensure an adequate resource supply. ]]> 2018-02-23 02:01:20 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234552824 https://padlet.com/karen_fong/qsah6p3usdja/wish/234552837 Another argument for increasing population is that it may lead to the shortage of resources. This is because the consumption of various resources such as water and soil might increase constantly. O’Sullivan (2016, p.18) believes that an increase of polulation may negatively affect Australia’s water and food security. Therefore, the government should not encourage increasing population , then the issue of scarcity of resources may be resolved efficiently.]]> 2018-02-23 02:01:27 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234552837 https://padlet.com/karen_fong/qsah6p3usdja/wish/234552999 Another argument is that dramatic growth in population will have some negative effects on resources.This is because a larger population will cost more resources than before.According to O'Sullivan(2016),Australia is facing problems of shortage in both water and crops,leading to dependance on sea water and import of crops.This means that there coul be a conflict between larger population and limited resources.]]> 2018-02-23 02:02:37 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234552999 https://padlet.com/karen_fong/qsah6p3usdja/wish/234553139 2018-02-23 02:03:46 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234553139 https://padlet.com/karen_fong/qsah6p3usdja/wish/234554201 2018-02-23 02:11:23 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234554201 https://padlet.com/karen_fong/qsah6p3usdja/wish/234554287 Another reason for not increasing population is that it may cause resource shortage. The larger the population becomes, the more the resources are needed. According to O’Sullivan(2016), insuffcient water and fertile soil have always been serious problem for Australia. Most capital cities in Australia in desperately need for water so they use desalination for water security in droughts. Moreover, the output of irrigated crops have been reduced. Thus, Australia should control its population because that it will not be food secure in drought years with over 30 million people.]]> 2018-02-23 02:11:57 UTC https://padlet.com/karen_fong/qsah6p3usdja/wish/234554287
