本校学生在今年3月参加了由 《生活的艺术》举办的环保许愿树计划。
从3月初开始,学生们各自创造并彩绘已用塑料瓶,并将祝福语放进塑料瓶里。接着,环保学会的学生将会将每50瓶塑料瓶串成一条直线,《生活的艺术》的负责人会到校收集塑料瓶。接着,他们会将来自不同学校的塑料瓶合成一棵环保许愿树。
由于这是一项公开给全校学生的活动,因此有很多学生踊跃参加。共有149位学生呈交他们设计的塑料瓶,但只有47位学生出席3月28日当天在Batu Kawan Stadium 进行的亮灯仪式。
3月28日当天,学生们在下午3时30分就必须在Tesco Tanjung Tokong 或Tesco E-gate集合。我们乘坐由《生活的艺术》负责人准备的巴士,在下午4时准时出发到Batu Kawan. 大概下午5时30分,两辆巴士都抵达活动地点。学生们用过晚餐过后,就进去体育馆内出席快乐浪潮讲座,以及见证历史性时刻– 马来西亚记录的”环保许愿树“。
那棵由全国82间学校收集的塑料瓶合成的长17米,直径达15米的许愿树的亮灯时间虽然短暂,但却美得让大家惊叹。希望大家放在瓶子内的愿望都能够实现。
大约晚上9点30分,大伙儿乘坐巴士,回到下午的集合地点。在一天的舟车劳顿以后,大伙儿带着疲惫的身躯回家。
在这里,非常谢谢各位环保学会的委员的热心协助,也很谢谢参与的学生如此有秩序地配合一切的安排,更谢谢另外两位老师的拔刀相助。谢谢你们让一切顺利地进行。

在2月28日当天,全槟城的环保学会的老师都到Penang Botanic Garden 为环保分站比赛作准备。 由于提倡环保,因此大家尽量拿可循环的材料来准备活动材料及题目。
3月7日当天,活动正式进行。全槟城7间学校的学生踊跃参与。大家在Penang Botanic Garden前集合以及一起享用早餐,带着轻松愉快的心情聆听活动简介与规则。每间学校的四位代表都被分派到不同的组别,一起合作完成当天的任务。
活动开始之前,老师与协调员分别到各自的岗位准备。学生们完成了每个分站的任务后,都会获得老师分派的一个信封。学生们需分析信中的内容,以确定下一站的位置。
参与的学生们都必须在Penang Botanic Garden内四处游走,只为了寻觅正确的分站地点。最后,每队的学生都发挥了合作精神,成功完成任务。
身为其中一位分站的站岗老师,我发现一些队伍很有默契,也很活跃地配合及达成任务的要求。学生们需要在烈日高空下在Penang Botanic Garden内进行活动,实在是辛苦了!谢谢你们的配合。此外,也感谢协调员的热心协助,让此次的活动得以顺利的进行。
最后,当然得恭喜在这个比赛当中荣获亚军的同学!:)

What is land pollution?
Land pollution is the deterioration (destruction) of the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources.
It occurs when waste is not disposed off properly, or can occur when humans throw chemicals unto the soil in the form of pesticides, insecticides and fertilizers during agricultural practices. Exploitation of minerals (mining activities) has also contributed to the destruction of the earth’s surface.
Since the Industrial Revolution, natural habitats have been destroyed, and environments have been polluted, causing diseases in both humans and many other species of animals.
Human actions have also caused many large areas of land to lose or reduce their capacity to support life forms and ecosystems. This is know as land degradation. Note that land degradation can result from many factors, and land pollution is only one of them.
In the lesson, we shall see the more about Land and Environmental Pollution, the sources of the pollution, its consequences and a few things we can do to prevent further pollution and protect our environment.
Types of land pollution.
There are different types of land pollution. Many publications group them differently. Let us see these four main types:
Solid Waste
These include all the various kinds of rubbish we make at home, school, hospitals, market and work places. Things like paper, plastic containers, bottles, cans, food and even used cars and broken electronic goods, broken furniture and hospital waste are all examples of solid waste. Some of these are biodegradable (meaning they easily rot or decay into organic matter). Examples include food droppings, paper products as well as vegetation (like grass and twigs). Others are not biodegradable, and they include plastics, metals and aluminum cans, broken computer and car parts.
Because these do not easily decay, they pile up in landfills (a place where all the city’s rubbish are sent), where they stay for thousands of years. These bring great harm to the land and people around it. See the complete lesson on WASTE here.
Pesticides and Fertilizers
Many farming activities engage in the application of fertilizers, pesticides and insecticides for higher crop yield. This is good because we get more food, but can you think of what happens to the chemicals that end up on the crops and soils? Sometimes, insects and small animals are killed and bigger animals that eat tiny animals (as in food chains) are also harmed. Finally, the chemicals may be washed down as it rains and over time, they end up in the water table below (causes water pollution).
Chemicals
Chemical and nuclear power plants produce waste materials that have to be stored somewhere. Fertilizer, insecticides, pesticides, pharmaceuticals manufacturers also produce lots of solid and liquid waste. In many cases they are stored in an environmentally safe way, but there are some that find their way into landfills and other less safe storage facilities. Sometimes they also find their way into leaking pipes and gutters. They end up polluting soils and making crops harmful to our health.
Deforestation
Humans depend on trees for many things including life. Trees absorb carbon dioxide (a green house gas) from the air and enrich the air with Oxygen, which is needed for life. Trees provide wood for humans and a habitat to many land animals, insects and birds. Trees also, help replenish soils and help retain nutrients being washed away. Unfortunately, we have cut down millions of acres of tree for wood, construction, farming and mining purposes, and never planted new trees back. This is a type of land pollution.
Sources of land pollution.
Below are some sources of solid and semi-solid pollutants:
Agricultural sources:
These include waste matter produced by crop, animal manure, and farm residues. They also include the chemical left over of all pesticides, fertilisers and insecticides used for agricultural activities.
Ashes: The residual matter that remains after solid fuels are burned. When waste is burned in incinerators, two types of ashes are produced. Bottom ash is the debris from burnt metal and glass waste. Bottom ash are not bio-degradable. The second type of ash is called fly ash. This is the ash that is trapped by filters in the chimney of the incinerators. It is know to be very toxic (poisonous). Every four trucks of waste burnt produces about one truck of ashes that end up in the landfill too. Ashes easily leak into the soil and water tables causing land and water pollution.
Mining sources: This includes piles of coal refuse and heaps of slag and underground debris. Mining and forestry activities that clear the land surfaces (clearcutting) and use ‘skid trails’ often leave leave the land unrestored. The surface is exposed to erosion which destroys the quality of the land. Additionally, iron and other chemicals such as copper, mercury and lead from mining practices leach into the soil, polluting it and leaving it exposed to water bodies as well.
Industrial sources: These include paints, chemicals, metals and aluminum, plastics and so on that are produces in the process of manufacturing goods.
Sewage Treatment: Wastes that are left over after sewage has been treated, biomass sludge, and settled solids. Some of these are sent directly to landfills whiles other treatment plants burn them to generate electricity. Both end up polluting the environment.
Garbage or waste: These include household or municipal waste such as glass, metal, cloth, plastic, wood, paper, and so on. Some of these can decay and others cannot. They are usually collected and sent to landfills where the pollution action begins.
Construction sources: These include waste like debris, wood, metals and plastics that are produced from construction activities.
Deforestation: This is when trees are cut down for economic purposes, mining, farming and construction. In forests areas, trees absord and reflect about 20% of the intense heat from the sun, protecting and preserving its surface soils. Cutting down trees mean that the land is exposed to direct sunlight and rain, resulting in soil erosions, desertification and land degradation
Chemical And Nuclear Plants: These include chemical waste from chemical industries that are disposed off into landfills.
Oil Refineries: When crude oil is refined into usable petro, gas or diesel, there are by products that end up as waste.

What is Noise Pollution?
Sound is essential to our daily lives, but noise is not. Noise is generally used as an unwanted sound, or sound which produces unpleasant effects and discomfort on the ears.
Sound becomes unwanted when it either interferes with normal activities such as sleeping, conversation, or disrupts or diminishes one’s quality of life. Not all noise can be called noise pollution. If it does not happen reqularly, it may be termed as ‘Nuisance’
Scientists also believe that its not only humans who are affected. For example, water animals are subjected to noise by submarines and big ships on the ocean, and chain-saw operations by timber companies also create extreme noise to animals in the forests.
Generally, noise is produced by household gadgets, big trucks, vehicles and motorbikes on the road, jet planes and helicopters hovering over cites, loud speakers etc.
Noise (or sound) is measured in the units of decibels and is denoted by the dB. Noise which is more than 115 dB is tolerant. The industrial limit of sound in the industries must be 75 dB according to the World Health Organization.
Noise is considered as environmental pollution, even though it is thought to have less damage on humans than water, air or land pollution. But people who are affected by severe noise pollution know that it is a massive issue that needs attention.
What are the sources of noise pollution?
Noise can come from many places. Let us see a few good sources:
Household sources:
Gadgets like food mixer, grinder, vacuum cleaner, washing machine and dryer, cooler, air conditioners, can be very noisy and injurious to health. Others include loud speakers of sound systems and TVs, ipods and ear phones. Another example may be your neighbor’s dog barking all night everyday at every shadow it sees, disturbing everyone else in the apartment.
Social events:
Places of worship, discos and gigs, parties and other social events also create a lot of noise for the people living in that area. In many market areas, people sell with loud speakers, others shout out offers and try to get customers to buy their goods. It is important to note that whey these events are not often, they can be called ‘Nuisance’ rather than noise pollution.
Commercial and industrial activities:
Printing presses, manufacturing industries, construction sites, contribute to noise pollutions in large cities. In many industries, it is a requirement that people always wear earplugs to minimize their exposure to heavy noise. People who work with lawn mowers, tractors and noisy equipment are also required to wear noise-proof gadgets.
Transportation:
Think of aero planes flying over houses close to busy airports like Heathrow (London) or Ohare (Chicago), over ground and underground trains, vehicles on road—these are constantly making a lot of noise and people always struggle to cope with them.

As technology improves, scientists are able to detect more pollutants, and at smaller concentrations, in Earth’s freshwater bodies. Containing traces of contaminants ranging from birth control pills and sunscreen to pesticides and petroleum, our planet’s lakes, rivers, streams, and groundwater are often a chemical cocktail.
Beyond synthetic pollution, freshwater is also the end point for biological waste, in the form of human sewage, animal excrement, and rainwater runoff flavored by nutrient-rich fertilizers from yards and farms. These nutrients find their way through river systems into seas, sometimes creating coastal ocean zones void of oxygen—and therefore aquatic life—and making the connection between land and sea painfully obvious. When you dump paint down the drain, it often ends up in the ocean, via freshwater systems.
In the developed world, regulation has restricted industry and agricultural operations from pouring pollutants into lakes, streams, and rivers. Technology has also offered a solution in the form of expensive filtration and treatment plants that make our drinking water safe to consume. Some cities are even promoting “green” infrastructure, such as green roofs and rain gardens, as a way to naturally filter out pollutants. But you may find a different picture in parts of the developing world, where there is less infrastructure—politically, economically, and technically—to deal with the barrage of pollution threats facing freshwater and all of the species that rely on it.
