Rubbish

A constant problem of pollution is the way to dispose of rubbish. No matter what the solution is, there will always be pollution.

Water Pollution
people usually dump them in the waters when there is a lake/river/beach

Causes: people are too lazy to throw it in the nearby bin and recycle it
Consequences: marine life is threatened, plants and animals alike.
Because of these selfish reasons/excuses lifes are at stake


This pitiful seal is trapped by a fisherman's net. It happens because of their laziness. When they go for their fishing and they caught something, the fisherman is too lazy to haul up the rest of the net and instead, cut the rest of it away. Their irresponsible behaviour will cause some unlucky animal like this seal, to swim into it and gets entangled. The animal then struggles until it suffocates without oxygen and die.


This turtle probably would not survive for long. It either gets captured by some fisherman or becomes lunch for predators. These fisherman are oblivious to how severely their actions are affecting the environment and they would not stop.



Air Pollution
Consequences: If the rubbish is thrown in the incinerator to be burned away, it does not contributes to air pollution, but warms up the atmosphere and slowly it leads to ozone layer depletion. Incineration and other high temperature waste treatment system are "thermal treatment".

Land Pollution
the common way to get rid of the garbage is landfill. Singapore has limited land and to use landfill as a solution, there should be a sufficient amount of land. This is suitable for other countries like America and China as they have more space to use as the dump.

Consequences: there will be a lot of land wasted by the dumping of thrash and these lands are unsuitable for any human activities.
