Environmental pollution - ✔✔caused by industrial waste has been referred to as a specific
type of corporate violence, comprising actual harm or risk inflicted on workers and the general
public as a result of deliberate decisions by corporate executives or
managers, or corporate negligence, the quest for profi t and wilful violation of health, safety
and environmental laws.
Types of Environmental pollution - ✔✔1 Air pollution
2 Water pollution
3 Solid and hazardous waste pollution
4 Noise pollution
Air pollution - ✔✔caused by solid, liquid or gaseous substances in the atmosphere, in
concentrations that are harmful to human beings or other living creatures, plants, property or
the environment
Water pollution may be defined - ✔✔as the contamination of water to such an extent
that it alters the physical, chemical or biological properties of the water so that it becomes
harmful or injurious to public health or safety, or to the life and health of animals, plants and
aquatic organisms.
serious diseases such
as typhoid, dysentery and cholera are spread through polluted water
Water pollution is one of the oldest environmental problems and is usually the result of
urbanisation, industrialisation and waste disposal. Industrial waste is the major cause of water
pollution in developed countries.
,More than 20|000 municipal waste-water operations discharge such water
into rivers and streams
The following are significant sources
of water pollution - ✔✔> Sewage and other oxygen-demanding waste contain decomposing
organic matter and pathogenic agents
> Industrial waste contains toxic agents such as metal salts and complex synthetic
and organic chemicals. Dangerous substances found in industrial waste include arsenic,
mercury, chromium, zinc, copper and nickel. Many of these heavy metals slowly build up inside
the organism ingesting them and when critical concentrations
are eventually reached, the organism dies
> Oil pollution, whether due to nonchalant navigation or the intentional cleaning
of ships' tanks at sea, may be considered one of the greatest pollution threats
to South Africa's marine and contiguous coastal biota
> Acid drainage from mines is another serious form of industrial waste pollution.
Sulphur-laden water leaches acid from the soil when draining from old abandoned mines as
well as active mines.
> Agricultural waste such as fertilisers, pesticides, biocides and other solid additives pollute the
water system. These substances are washed off the land through irrigation, rainfall, erosion and
drainage and subsequently leach into rivers and streams where they seriously disturb the
aquatic ecosystem. Once deposited into natural (aquatic) systems, these substances also give
rise to a process known as
eutrophication. Certain plants, especially alien biota, plants and fish readily assimilate these
products into their biomass
and burgeon as a result. This in turn leads to natural systems in a macro and/
,or microsense becoming choked by the sudden (primary) growth.
> Thermal pollution is caused by chemical industries, fossil fuel and nuclear power plants that
use copious amounts of water for cooling purposes and then return this water at a higher
temperature to the river, lake or sea from which it was drawn. This outflow interferes with
natural conditions i
Solid and hazardous waste pollution - ✔✔Solid waste other than hazardous materials and
radioactive waste comprises materials
discarded by a community such as garbage, food waste, organic material, glass, tin cans, paper
and ash
Noise pollution - ✔✔defined as unwanted or extraneous sound or as unwanted sound
pumped into the atmosphere, causing a health hazard. may also be defined as an excessive,
offensive, persistent or startling sound that causes fatigue and physical and psychological
problems such as hypertension, deafness and tension
three categories of traders in the illegal trade in
rhino horn - ✔✔• poachers
• runners
• wholesalers
Although financial reasons are the most important reason for rhino
poaching, there are also a number of other reasons: - ✔✔• Trouble. The more trouble one
experiences during the poaching process, the more status one earns, especially in rural
societies.
• Excitement. The challenge of not getting caught by game rangers or the police is very exciting.
• Being smart. Poachers enjoy outmanoeuvring law enforcers. They also enjoy
, exhibiting their knowledge of guns, hunting tactics and use of special equipment
during hunting expeditions.
• Being tough. Poachers enjoy being tough. They will not allow law enforcers to
arrest them and will do whatever it takes to get away, even paying with their lives if necessary.
• A sense of autonomy. A sense of independence is at least partially satisfied by illegal hunting.
By poaching, these individuals are playing by their own rules.
Transnational conservation crime - ✔✔truly global in scope, and refl ects broad
socioeconomic
processes and trends associated with globalisation. The diversity and complexity of
such harm can be understood in terms of national borders and international social
processes, and the pressures of and limits to economic life shaped by the dictates of
21st-century capitalism
United Nations environmental conference identified three specific areas where hazardous
waste requires urgent attention. - ✔✔• The proliferation of e-waste generated by the
disposal of tens of thousands of computers and other equipment
• The safe disposal of old ships and aeroplanes, which likewise contain metals, chemicals and
other contaminants
• The illegal shipping to and dumping of hazardous waste materials in countries made
vulnerable by weak regulatory or enforcement systems
Factors contributing to illegal trade in endangered species - ✔✔• Cultural (causes) issues
There is a big demand for rhino products among Asian communities whose cultural traditions
believe rhino horn to be an aphrodisiac for which they are willing to pay
large amounts of money.
