人口上升對地球的影響(功課)快

1.加速資源的耗用
人口愈多...所需的資源也會上升..令地球的資源政加短缺

2.破壞生態系統
人口上升..為了滿足生活的需求..人類會大肆改變周邊的生態..例如大量森林被開墾以成為人類居住的地方等..當林木被過份砍伐..會造成氣候改變..釋放大量的溫室氣體..引致全球暖化.溫室效應等問題

3.污染環境
人口上升..對日常必須品的需求也會上升..加增工業的發展..工商業的活動..會增加對地球的污染..例如空氣..土壤..河流等的污染

人口上升對能源的需求會漸漸增加
若化石燃料被開發盡了．．．
那就需要靠可再生能源
如果可再生能源，例如：風力發電
一但風變得弱,人類就沒有能量用

1.導致溫室效應,,
2.過度捕魚
3.糧食供應不足,,令人餓死
4.加快消耗能源

Greater consumption of resource
this is 1 of the major problem
'cos it bring a heavy weight to society
also increase the speed of damge to environment (more consumer, more exhause)
and lead to the price of resource increase (Supply & Demand^^)

other than that
it will cause illness, due to the crowed space, and people fight for resource
so it will bring conflict too.....

there are too many to say, depend on which subject u r studing, basically u can do it in Political, Economical, Cultural..etc, (there are many more to go.......)
