At GOES Foundation, we are marine biologists, 30 years field experience

Life support systems for public aquaria and marine mammals

Environmental projects and effluent treatment systems in India and China we know about environmental pollution and what is takes to destroy and ecosystem

Freshwater pollution……Un-sustainable Economies

Economies of countries including India, China are un-sustainable unless they prevent aquatic environmental pollution• 90% of surface water is polluted with priority chemicals• 75% of all aquifer water is grossly contaminated• All freshwater pollution eventually ends up in the oceans

Mass of garbage is 6 times the mass of plankton in garbage patches

46,000 pieces of plastic per square kilometre, killing a million seabirds and 100,000 marine mammals each year

Priority chemicals impact on microscopic plankton (primary productivity)

Priority Chemicals, what are they?Chemicals or substances that pose an unreasonable risk to; • Public health, carcinogenic, mutagenic, teratogenic, neurological,

endocrine disrupters and auto-immune disorders• Environment, water and food security, we depend upon the marine

ecosystem, if we loose it, the terrestrial system will fail

• 90% of all cancers are now known to be caused by environmental factors• 800 billion year on treating neurological problems• 200,000 tonnes of priority substances are manufactured in Europe every year.

Ref MARBEF1. PCB concentration in the North sea, 8.8 ng/l, concentration in biomass 600 to 1200 ng/g

(dry weight)2. PCB concentration in Antarctic 1.2 ng/l, concentration in biomass is the same as North Sea

600 to 1200 ng/g (dry weight)3. The above demonstrates that hydrophobic particles, concentrate priority substances.

UK, National Health Service“Pregnant women should not eat more than two oily fish per week from the North Sea because of pollutants such as dioxins and PCBs (polychlorinated biphenyls)”

Oily fish are meant to be healthy ?

The implications of priority substances on Marine Biodiversity

Page 27: Climate change and toxic chemiclas

95% of all life in the oceans are microscopic plankton responsible for up to 80% of all our Oxygen

30% of CO2 fixation. Atmospheric oxygen levels are declining, and CO2 is increasing

Page 28: Climate change and toxic chemiclas

Dalhousie University Nova ScotiaPrimary productivity has dropped by 40% since the 1950s. Nature 466, 591–596 (29 July 2010) doi:10.1038/nature09268

NASA from satellite imagery shows that primary productivity is dropping by 1% every year.

The drop in productivity is not due to increasing temperature.Priority chemical product started in the early 1950s, is there a Connection with the drop in productivity?

Page 29: Climate change and toxic chemiclas

pH and ocean acidificationCO2 dissolves into the water and drops the pH

At current rates in 25 to 40 years, oceanic pH will drop from pH8.06 to pH7.95, at which point there may be a cascade destabilization of the marine ecosystem.

The ability of the marine ecosystem to sequester CO2 will decline in proportion to the productivity

Anthropogenic CO2 emission account for up to 3.75% of the total CO2 going into the atmosphere

each year. (from IPCC)

Data from IPCC

pH at 2015

pH at 2050

Representative Concentration Pathways (RCPs) 8.5combines assumptions about high population and relatively slow income growth with modest rates of technological change and energy intensity improvements

Consequences

When the pH reaches 7.95 in 25 to 40 years, the consequences could be;

• No more marine teleost fish• No fish then no dolphins, whales, seals,

penguins, seabirds or polar bears• Food supply for 1.5 billion people under

threat• Coccolithophores will be replaced by

diatoms, fixation of atmospheric CO2 drops by at least 50% climate change accelerates

Page 31: Climate change and toxic chemiclas

For discussion?

If priority chemicals are implicated in reducing primary productivity, allowing CO2 to increase, could we reverse the trend?

Opportunities… for a non toxic environment

• Communicate the problem• Development of new domestic

products, cosmetics, cleaning agents, fire retardants

• Pharmaceuticals, domestic treatment systems

• Technology to recycle waste, eg PCs, mobile phones

• Prevention of pollution, disposal stratigies & catchment area management

• Water treatment technology to remove the chemicals from drinking water and wastewater.

Page 33: Climate change and toxic chemiclas

Reduction of oceanic pollution would allow the marine ecosystem a chance to recover…

and this could happen very quickly…

Page 34: Climate change and toxic chemiclas

Trees take over 100 years to remove CO2 carbon from the atmosphere

Page 35: Climate change and toxic chemiclas

35Marine Algae takes a few hours / days

Page 36: Climate change and toxic chemiclas

36

Marine Bacteria take a few minutes

Page 37: Climate change and toxic chemiclas

If we remove the brakes on marine productivity by preventing pollution, the marine ecosystem could

recover very quickly.

Page 38: Climate change and toxic chemiclas

The prevention of priority chemicals getting into the air and water, may be our best hope to protect not only the

oceans but the terrestrial ecosystem.but

we need to take action now we may only have 25 years to provide a fix.
