Land Pollution

The Cause,

• Human beings create tons of domestic waste every day, so many landfills were formed such as Tseung Kwan O (將軍澳 ) landfill site and Ngau Chi Wan(牛池灣 ) landfill site.

The Cause,

• Some people litter or spit on the street.

• Agricultural activities produce waste because the farmers used pesticides to kill bacteria in crops. It pollute the land when they are washed into the soil.

The Effects,

• The filling of rubbish into the landfill sites cause land pollution.

• The landfill sites store a lot of rubbish and put them together, some may through chemical reaction to create some harmful gases.

• Also, after the landfill was full and became a flat land, the land use of this land limited, it can only use for recreation so it may lost it’s own value.

The Effects,• People is polluting the land when they are

littering and spitting. It affect the image of Hong Kong . Also, the things spitted by those people may spread some diseases.

The Effects,

• When the pesticides washed into the soil, land was polluted. The farmland cannot farm for a long period of time.

Existing Measure,• The government re-plan to burn the rubbish by

incinerator to replace filling rubbish to landfills.

• By penalty: People who throw rubbish on the street may pay $1500 for fine.

Existing Measure,

• By education: The government educate people to recycle the rubbish by advertisement.

Existing Measure,

• The government helped some farmers in the New Territories to promote organic farming to reduce land pollution.

• The government plan to charge people who throw rubbish to the landfills.

Further Suggestions,

• The only way to reduce land pollution is to reduce the need of landfills. To reduce the need of landfills, we need to reduce the creation of rubbish:

• We can use the paper on both sides.• The government may increase the penalty.• We can reuse the plastic bottles.• Set up laws to limit the creation of rubbish.• We can use recycle bag to replace plastic bag.
