5. All cruise ships generate the following types of waste:
โ "Gray water" from sinks, showers, laundries and galleys
โ Sewage or "black water" from toilets
โ Oily bilge water
โ Hazardous wastes (including perchloroethylene from dry cleaning, photo-processing wastes, paint
waste, solvents, print shop wastes, fluorescent light bulbs, and batteries)
โ Solid wastes (plastic, paper, wood, cardboard, food waste, cans, and glass)
โ Air pollution from the ship's diesel engines, especially those using heavy fuel oil (high sulfur content)
โ Polluted discharge containing fuel, lubricants and chemical additives from sulfur oxide scrubber wash
water effluent (when used, see regulations section below for details)
8. 1)Large-scale use of chemicals for cotton cultivation
Cotton is a heavily sprayed crop.
This ruins the soil and deprive it of
the natural replenishment of
nutrients. Runoff pesticides,
fertilizers, and other chemicals
result in massive water pollution.
9. 1)Large-scale use of chemicals for cotton cultivation
Soluble pesticides were
carried away by water
molecules especially during
the precipitation event by
percolating downward into
the soil layers and eventually
reach surface waters and
groundwater. Consequently, it
degrades water quality and
reduces the supply of clean
water for potable water.
10. 2) Inefficient irrigation systems
Surface and ground
waters are often diverted
to irrigate cotton fields,
leading to freshwater loss
through evaporation, and
inefficient water
management.
12. 3) Poor drainage systems
Poorly maintained drains
would cause flooding,
which causes enormous
damages in the
agricultural land and
the irrigation network.
Excess water on farms,
in turn, results in the
leaching of essential
minerals and the
pollution of rivers.
13. River pollution and Marine Dumping
Global relevance:
-Rise in the the rate of starvation and diseases
-Destruction of biodiversity
National relevance:
-Bad effects on food chain
-Bad effects on animals
23. How to change consumption behaviour?
1)Make it relatable
2)Make it desirable
3)Make it contextual
4)Make it easy

25. Convincing Others To Care About The Environment
*Start with people you know
*Create an online group
*Organise a gardening club
*Do school tours
*Create a video
*Organize meeting

27. Business agricultural activities impact upon water...
โฆthrough industrial and agricultural withdrawal
Seventy per cent of freshwater withdrawn annually for human use is for agricultural
irrigation and 15 to 35 percent of this withdrawal is estimated to exceed supply. The misuse
of surface and ground water displaces water flows and disrupts cycles. Water is embedded
within products that are transported across the globe from areas of varying water
availability; business can therefore contribute to local water scarcity. Overexploitation of
water resources can decrease long term capacity and force operations to be displaced to
more secure water areas. Misuse of surface and ground water sources may also spawn
tensions between users and cause reputational damage as well as fuel questions around
regulations and licences to operate.
28. Business agricultural activities impact upon water...
โฆthrough pollution of waterways
Pollution can occur as a result of businesses discharging substances into surface waters or
groundwater without prior treatment. It can also occur inadvertently through chemical spills or
leaks, trade effluent, silt accumulation or agrochemical runoff. It is often an offence to pollute
waterways as this disturbs aquatic ecosystems and decreases water quality for other users as well
as for future business needs. Polluting waterways can lead to reputational controversy,
infringement of local legislation and increased water treatment costs.
29. Business agricultural activities impact upon water...
โฆthrough land use and infrastructure changes
While the distribution of water around the world is uneven, business activities and practices have
further altered the distribution of water through land use and infrastructure changes. The removal
of vegetation and deforestation for the expansion of business operations alters plant stem water
flow, infiltration rate and evapotranspiration processes within local environments. Damming and
irrigation also displace water and alter natural processes within aquatic ecosystems. Modifying
hydrological cycles can, at a global level, lead to increased extreme weather events like storms and
droughts. At a local level, changing water flows can affect water availability and quality. This can
have implications on input costs as water may need to be treated or diverted before use.
30. The Pasig River in the Philippines suffers from a high level of water pollution and
efforts are being made to rehabilitate it.
The river takes its name from the
city of Pasig, which is named after
the Tagalog word pasig, meaning
"a river that flows into the sea" or
"the sandy bank of a river", with
the former in reference to the
Pasig River's flow from the
Laguna de Bay towards Manila
Bay and out into the South China
Sea.
