THE GREEN MOVEMENT

I Environmental pollution

• The litter problem on the coast of Guyana, 2010

• Air pollution in the US, 1973

• Smog Pollution in Taiwan

• The Lachine Canal in Montreal,Quebec, Canada

• Chemicals from factories

• Waste water from factories

• Air pollution

• Workers collect dead fish at a park in Shenzhen, Guangdong province, on 5 November, 2013 More than 10,000 fish were found dead in a smelly lake, near a drain where sewage flowed into it

• Environmental pollution in VN

II Causes of pollution

There are many causes for pollution

• Air pollution can be caused by both human and anthropogenic sources

• The main contributors for air pollution are human-made pollutants due to activities like combustion, construction; mining, agriculture and warfare are significant

• Emissions from motor vehicles are one of the leading causes of air pollution

• Pollution sources that are stationary include chemical plants, coal-fueled power plants, petrochemical plants, oil refineries, nuclear waste disposal, large live stock farms, incinerators, factories producing PVC, metals, plastics and other heavy industry

• Pollution from agriculture comes from clear felling, burning and spraying of pesticides and herbicides Humans are the primary cause

of global warming since 1950s

• Soil contaminants include chlorinated hydrocarbons, heavy metals, solid hospital wastes, lead, fuel Ordinary landfills are the source of chemical substances entering the soil environment

• Water pollution can be caused by discharge of toxic pollutants like pesticides, heavy metals and non-degradable chemical compounds into fresh or ocean waters

The sources of these can be industries, chemical, heavy metal, hospital wastes They also can be untreated or partially treated sewage water

III Effects of pollution

All types of pollution – air, water and soil pollution – have an impact on the living environment

The effects in living organisms may range from mild discomfort to

serious diseases such as cancer to physical deformities; ex., extra or

missing limbs in frogs

• Environment pollution greatly affect the flora and fauna on earth

• Acid rain (formed in the air) destroys fish life in lakes and

streams

• Excessive ultraviolet radiation coming from the sun through the ozone layer in the upper atmosphere which is eroded by some air pollutants, may cause skin cancer in wildlife

• Ozone in the lower atmosphere may damage lung tissues of

animals

• Nutrient pollution (nitrogen, phosphates etc) causes

overgrowth of toxic algae eaten by other aquatic animals, and

may cause death; nutrient pollution can also cause outbreaks

of fish diseases

We know that pollution causes not only physical disabilities but also psychological and behavioral disorders in people

• Reduced lung functioning

• Irritation of eyes, nose, mouth and throat

• Asthma attacks

• Respiratory symptoms such as coughing and wheezing

• Increased respiratory disease such as bronchitis

• Reduced energy levels

• Headaches and dizziness

• Disruption of endocrine, reproductive and immune systems

• Neurobehavioral disorders

• Cardiovascular problems

• Cancer

• Premature death

IV How to reduce pollution

1 Encourage friends and relatives to join green activities

2 Take part in tree-planting event

3 Refuse plastic bags when shopping

4 Turn off the lights when leaving home

5 Save the non-renewable energy and use solar energy calculators, watches and other accessories

6.Use Clean Sources of Energy
