The Dangers of Biological Pollution

Biological spills cannot be usually cleaned up like oil spills, and the waste is of a different kind.

In a year about 2.4 million gallons every hour or forty thousand gallons every minute and 21 billion gallons ballast water with thousands kinds of dangerous species are spread into US Water environment.

In the bay of San Francisco 234 species, about 139 species in the Great Lakes, 154 in the Hudson River, New York, 67 in Coos Bay, 154 in Florida Inland Water in Chespeake Bay about 120, in Hawaii 4,466 species are found and are expected to produce about 15 % serious harm to the environmental conservation

Percentage of Damage

According to the OTA Report the harmful introductions rate looked stable and from 1980 to 1993 it was 200 and the expected harmful introduction was about 59. However, it is mainly on the non-indigenous species and they are unrecognized and bring stress to the ecosystem.

Zebra Mussels

They were introduced in Lake St Clair in the year 1986 in water discharges which now fill water from Vermont till Oklahoma as well as Ontario till Gulf of Mexico.

Zebra mussels are monitored and controlled by Great Lake water users spending 30 million dollars of Conservation of environment had impact on the fishery resources and effort to restore fisheries.

Spreading of Mitten Crabs

During 1992 mitten crabs have been originated in the Southern Bay of San Francisco.

Levees and banks are being threatened by burrowing thus giving protection to urban and agriculture environmental conservation areas.

Commercially significant species like craw fish were to be competed and damage caused to catch and fishing nets. It was a nuisance to fisherman who catch fish for recreation.

Brown Tree Snake

During World War II it was found in military equipment returning from war.

At present it is found in Guam, Saipan, Hawaii, the US Mainland and further pacific Islands.

1200 electric current outages were caused on an average of only one in 5 days ever since 1980 and it has spread island wide and lasted for many days.

The population of brown tree snake is increasing and it is likely that the population of trout declines ten to twenty percent.

The Yellow Stone Lake is being threatened by world’s renowned fishery and trout fishery may become less important economically and socially. Depending upon the accessibility of yellow stone cut throat trout many species are found in great quantity in the environment but lake trout does not fulfil the environmental conservation niche.


In 1980 Ruffe was introduced in Duluth, MN/Superios WI harbor and through the years it has spread all along the eastern coast along Lake Superior as well as Lake Huron for about 150 miles, causing the decline of native fishes.

The decline of fisheries within US Great Lakes is estimated to be around $119 million due to ruffle intervention.

Sea Lamprey

In 1929 when Welland Canal was opened, Sea Lamprey invaded the Great Lakes.

In 1940 and 1950 it became the main cause for the decline of fisheries and lake trout population.

US environmental conservation spent $12 million every year to control them and the population was reduced by 90%. Lake trout has been restored due to this environmental conservation effort.


Almost 100 millions of acres of the environmental area have been affected by weeds and it keeps increasing by ten million acres each year.

The pace of invasion of lands through weeds is 4600 acres every day. According to Baltimore Dumpster Rental Whiz, the environmental conservation federal agencies spent $ 11 million to eliminate weeds. 1.4 millions Of acres of FWS land in the outskirts of Alaska was affected.

U.S Economy

Money spent to conserve environment is billions every year.

From 1906 till 1991 money spent to conserve environment from 79 plant and animal species was $79 billion. It is estimated that by 2050 $134 billion will be the cost of the15 latest introductions.

The sea lamprey management of environmental conservation will cost $12 million per year. $45 million per year is spent for purple loose strife control.

The money spent by the six federal environmental conservation agencies regarding weeds is $11 million per year. $119 million is spent on the decrease of commercialized fisheries in US due to ruffle population. $30 million is spent every year on zebra mussel control in Great Lakes.

Productivity loss of range lands because of weeds is $ 3.6 – $4.5 billion and 64 crops productivity loss because of weeds in 1984 is $ 7.8 billion.

Ecosystem Restoration

Historic circumstances are not a valid guide to the rate of restoration received.

Before effective restoration is done new objectives and goals have to be developed and delay for additional investment and study is required.

Florida Everglades

Water level is lowered due to Malaleuca. Native vegetation is assorted by Brazillian pepper tree and Melaleuca and has been replaced with single, sterile species stands.

San Francisco Bay

Many invaders have changed the ecosystem component and food web. The data collected in 1970 for Salmon restoration objectives and goal depending upon the population is no longer valid.

Optimal Waste Management Systems

The recovery objective as provided for in recent laws is not subject to any quantified obligation, just as it does not establish any hierarchy between on the one hand the material recovery, which consists in the production of new raw materials from the recycling of materials or the composting of organic materials, and on the other hand energy recovery, that is to say the production of electricity or district heating from thermal processes including more common is incineration.

Faced with the increase in incineration capacities, quantified recovery targets will be introduced (targets quantified by type of material (packaging), etc.) and attempts to establish a hierarchy between the recovery methods. The recovery effort that became widespread in the 1990s focused mainly on packaging. For several years now, there has been a trend towards recovery based on an approach of end-of-life products (tires, end-of-life vehicles, waste electrical and electronic equipment). This development which stems in particular from European regulations, gives rise to the production of specific regulations by sector, in a logic of producer responsibility.

In addition to the constraints of a regulatory nature, the lever of financial aid is used to impose valuation objectives, or even to establish a hierarchy between the valuation methods. Incineration is only subsidized on condition that it includes energy recovery. Then from 1996 the incineration aid paid to communities was based on the results obtained in terms of recycling and composting.

Thus there is a differentiation between the recovery methods: energy recovery must be preceded by one or more forms of material recovery. It was in 1998 that an ambitious 50% material recovery target was set, thereby establishing a hierarchy between material recovery and energy recovery. That said, this new objective, set at the national level, gave rise to confusion as to its translation into departmental plans.

Despite these inflections the insufficiency of aid intended for the financing of separate collections and composting, coupled with a lack of legal incentive in recovery, will not allow a commitment of the communities towards advanced recovery systems, to the benefit of a shift towards incineration and energy recovery, which appear to be easy solutions combining high technical reliability and social acceptability assumed to be greater than landfilling. Incineration plant projects carried out by local authorities, supplying district heating networks and or the electricity distribution network, become energy recovery units.

The issues of valuation and prioritization will be renewed at the turn of the year 2000 with the rise of concerns about climate change. The waste sector, mainly producing methane and CO2, estimated to be responsible for 3% of global greenhouse gas emissions is invited to take part in the national effort to reduce emissions.

The climatic challenge thus updates the link between waste management and energy production born with the oil shock of the 1970s. Taking into account the atmospheric and energy impacts of waste takes on a double meaning: the waste sector, called upon to helping to reduce atmospheric emissions (especially methane through the recovery of biogas from landfills), also appears to be an alternative energy supplier sometimes qualified as renewable.

With the fight against climate change, the recovery and recovery of energy from waste treatment (incineration with production of heat and electricity, anaerobic digestion, landfill biogas) see their interest increase. The waste is indeed part of the biomass and therefore participates in the production of renewable energy.

The abandonment of the idea of ​​hierarchy between types of recovery then prevails within the institutional and professional spheres, reinforced by the development of methods for assessing environmental pressure which promote a global understanding of impacts such as the analysis of life cycles.

The concern for a global environmental assessment integrating the question of atmospheric impacts is included in the regulations relating to waste management planning: from 2005, departmental and regional plans for the elimination of household and industrial waste are subject to an environmental report.

This redesign of the impact assessment, marked by the attention paid to greenhouse gas emissions, however comes up against difficulties in circumscribing the scope of the measure: should we, for example, take transport into account? impact assessment of waste management systems?

What Type of Waste is Found at Sea

With the frenzied advance of progress and consumption, human beings produce more and more waste. Whether they come from countries with recycling systems or not, a lot of this waste ends up at sea.

Garbage at sea in figures

This news made the headlines: there would exist in the Pacific a continent of waste consisting of 334,000 waste per km2 on average. In the European ocean depths alone, the number of litter is estimated to be over 540 million.

Origin of waste at sea

Among the waste found at sea, the proportion of land-based waste would be 80% against 20% of maritime origin. This terrestrial waste is that which one can imagine on a tourist beach: plastic packaging, shoes, butts and cigarette packs, empty bottles, etc. All this without counting the wastewater discharges during sewer overflows, for example. Marine litter comes from fishing activities: lost nets, ropes, traps and other used equipment, etc.

Environmental problems

Obviously, all this waste has a heavy impact on marine flora and fauna. Thousands of marine animals die each year due to the discharge of toxic fluids or gases, the ingestion of materials that are impossible to digest (plastics or rubbers) or victims of fishing nets thrown into the sea.

Each year, in France and elsewhere, coastal municipalities organize days of waste collection on the beaches. Do not hesitate to inquire to participate.

Ultimate waste

According to the Environment Code, an ultimate waste is defined as any waste resulting or not from the treatment of a waste, which is no longer likely to be treated under technical and economic conditions of the moment, in particular by extracting the recoverable part or by reducing its polluting or dangerous nature.

In other words, a waste is said to be ultimate if there is no way to reuse it in any way whatsoever, through composting, recycling, energy recovery, etc.

Ultimate waste is, on paper and since 2002, the only one that can be stored or buried in a waste storage center. On paper, because their definition which incorporates a notion of technical and economic conditions of the moment can give free rein to various interpretations.

Some examples of ultimate waste

The example of organic waste is one of the most striking. There are indeed techniques for composting organic waste and the operation can be done under entirely acceptable economic conditions. However, in the absence of separate collection and treatment of organic waste on a regional scale, the community can accept the landfill of this type of waste.

As for the real ultimate waste, it still constitutes a large volume to be stored or buried. These include, for example, medical waste, paints, rubble (tiles, concrete, ceramics, etc.) or cleaning products, etc.

Vermicomposting means recycling its waste with earthworms. To easily recycle organic waste, nothing better than vermicomposting. This technique based on the natural activity of earthworms is developing more and more because of its ecological and economic advantages.

Hello world!

The Toronto Japanese Short Film Festival had its first successful year in 2003. We expanded our programme the following year in response to a large number of qualifying entries and a strong audience reception. We are pleased to announce the third annual Toronto Japanese Short Film Festival will be held in November 2005. We hope you will join us for a new series of interesting and innovative Japanese films.

TJSFF is produced by the award-winning Belltower Theatre. The Festival was founded in June 2003 to expose a side of contemporary Japanese culture that has not previously been seen at other Toronto festivals and events.

Toronto has many wonderful film festivals year round that allow people to be exposed to other cultures. We feel that this is a great city for learning, accepting and respecting diverse cultures so we decided to introduce Japanese culture to the community by holding this festival.

We present various short films created both by Japanese filmmakers and international filmmakers whose work relates to Japan. We believe that this event is a fine opportunity to give them a voice and the recognition they so richly deserve.
