Part C: Impact of Man on Jurong Lake Park










IMPACTS OF MAN ON Jurong Lake Park 


 1) Littering  
Humans polluted the environment by casually dumping litter, example, sweet wrappers, can drinks, cigarette butts, and plastic bags and bottles caps on the ground or into the lake. As such, they turned the originally clean and hygienic park into a dirty one. The lake is also filled with murky water, affecting aquatic life greatly. And as a result, many fishes were unable to adapt to their new environment and died. Our school, JSS (Jurong Secondary School) and together with the JSS teachers and students had noticed the various problems and decided to raised these issues. I hope by doing so, many park users will be more aware of their doings in the park.  How is littering going to affect the park?  Litters like plastic bags, decomposed at a very slow rate in the environment. The plastic will produce chemicals when they slowly decompose and the chemicals are harmful to the plants. The animals eating the plants will be affected in a way or another too. They also pollute the water and the marine animals living in the lake. The plastic bags can trap fishes in them and thus, due to lack of oxygen and food, the fishes will gradually die. Nevertheless, litter also destroys the beauty and scenery of the park which make people avoid these areas. We hope that there will be more users in the park and we can join forces together to protect the park for more people to see and know.


2) Deforestation
  Trees are very important as they produce oxygen for humans to breathe. Without them, we are not able to survive. Unfortunately, man is capable of introducing large amount of carbon dioxide into the environment through human activities which put an extra burden on nature in the ecosystems, which can upset the balanced state of the natural cycles.  Some human activities include deforestation. It is evident that the increasing exploitation of land for human use greatly reduces the area of each wildlife habitat as well as the total area surface.  Deforestation can lead to:- Lesser species diversity, due to reduced habitable surface area.- The reduction of the size of habitats and thus reduces the genetic diversity of the species living there.This has significant negative impacts on the organisms’ survival. The conditions under which the reduction of habitats often occur prevent living organisms making use of their normal ways to flee their threatened habitat. Those escape routes include migration to other habitats and adaptation to the changing environment. To make matter worse, when organisms cannot adapt to their new habitats, they may die. 

3) Oil spill

image of oil spill have been taken on Jurong Lake Park. We hope to prevent this from happening as it may affect the marine life which includes the fishes. It is a form of pollution and it is mainly due to human activities. It usually happens when products like crude oil is released from tankers, off shore platforms, drilling rigs and wells, as well as spills of refined petroleum products ( such as gasoline and diesel). It is suspected that the pollution is caused due to many oil tankers that are parked near Jurong Lake Park. The oil that is unconsciously wasted flowed into the drains which are connected to the Jurong Lake. Though oil spills can be controlled, but it may take weeks for chemical dispersion, combustion, mechanical containment and absorption. It takes weeks, months, or even years to clean up. Though it takes a long time, at least there will be a certain changes done to the environment. But even so, it will affect the marine life living in Jurong Lake Park.
