International Biodiversity Conference
2010 VCAA EXAM

With increasing prevalence of environmental issues on a global scale, controversy has risen from whether ‘we’ as humanitarians are taking responsibility for our actions. A transcript of Professor Chris Lee’s speech at the 2010 International Biodiversity Conference asserts that, ‘the time to talk is over,’ and that now “is the time for serious action” to be taken towards making amends for the environmental damage and economical imbalance in society today. Lee contends that we must re-establish fundamental goals for the future, and to ultimately “safeguard the variety of life on earth: biodiversity.” Accompanying images, a ‘2010’ header and an image of the earth in a human’s palms highlight the importance and vulnerability of earth’s future, supporting Lee’s overarching message. The issue of ignoring biodiversity is complicated primarily by the broader implications of disparate power, which is reflected by the “continuing pattern of inequitable and untenable growth on a global scale.”

Through Chris Lee’s informative yet sincere tone, his opening paragraphs are characterised by use of time as a reference to reflect progress. The diminishing landscapes of the “past 100 years”, commitments made from “eight years ago” and the level of education “to date” positions the reader to question whether alongside our educational intellect, our knowledge and awareness of the earth has followed. Moreover, facts and statistics are continually listed including the “lost 35% of mangroves and 40% of forests” to increase Chris Lee’s credibility and reliability, which in turn, predisposes the listeners to adopt his latter assertions. Veracity and sincerity is maintained throughout his speech to ensure that his audience, “leaders in the area of biodiversity” are willing to listen and advocate Chris Lee’s perspective as they are essentially the most apt to educate secondary audiences that consist of “the politicians, the corporate

    In Robin Wall Kimmerer’s book Braiding Sweetgrass, she makes a compelling argument for the planet’s sustainability. Through several chapters, she illustrates how, despite how the Earth provides for all of our needs, we do not repay the favour and instead destroy the life it has left. We are not realizing the value of preserving the environment; instead, we are adapting to the thought that the extended use of fossil fuels is typical, climate change is irreversible, environmental pollution is an unfixable problem, endangered species are beyond salvation, and society has become increasingly disconnected to the planet as it once was. Kimmerer articulates this throughout multiple chapters.…

    Gore vs. Suzuki

    David Suzuki’s A Sacred Balance and Al Gore’s A Climate Emergency both outline the detrimental ways in which technology, population growth, and our way of living have begun to and will continue to destroy our diverse ecosystem. However, the outlooks that these two environmental giants have on man’s role in the world are perfectly opposite. “There is no environment ‘out there,’” urges Suzuki, “we are born of the earth and constructed from the four sacred elements of earth, air, fire, and water” (432). Gore, contrastingly, doesn’t look at humans as part of the interconnected “web,” but as rather just “[having an] impact on [the earth]” (456).…

    After an 8 year old global commitment to reduce biodiversity loss, Professor Chris Lee speaks at the 2010 International Biodiversity Conference. On the 25th to the 27th of October, Lee makes a speech entitled 'Taking Stock ' to an audience of leading environmental experts and leaders of respective countries. In a formal and direct style Lee contends that not enough has been achieved in the way of reducing biodiversity loss and more needs to be done to prevent further diminishment. Lee 's opening slide has the year '2010 ' with shadows of various animals, a tree and happy people holding hands as holes in the numbers. This sets the opening tone of the piece as a congratulatory speech of achievements and encourages the viewers to listen on.…

    Duty and responsibility to the living and non living aspects of Earth seems reasonably obvious to the common person. Humanity has been gifted with awe-inspiring and picturesque scenery and worthy resources that have allowed us to evolve past the belittled ape or animal. Yet, even through our actions in past and present, humanity has shown an aptitude for non-committal towards their obligation to the very thing that provides them with life. The over-industrialised world, monopolistic commercialism and disreputable capitalism have led to the metaphorical hell on earth represented in Scott’s panorama of…

    In recent times, it has become increasing clear that economic development and population growth are resulting in expeditious changes in natural ecosystems, globally, and particularly on the self-sufficient ecosystems of Hastings Point. In acknowledgment of this, the United Nations’ Kofi Annan presented a report: “We the Peoples: The Role of the United Nations in the 21st Century.” (2000) Annan called for Millennium Ecosystem Assessment in order to establish the consequences of change in ecosystems for the well-being of humans, and to specify the importance of conservation actions needed to enhance the sustainable use of services supporting various aspects of human life (2000) (Alberti, 2005). Findings from the report and recent studies situated…

    Severn Cullis-Suzuki was only 12 years old when she spoke before the UN earth Summit in Rio De Janeiro, Brazil, in 1992. A child speaking before adults representing all the countries in the world, yet her speech was anything but childish. It was an astonishing advice and an appeal to everyone to help stop the destruction of the earth’s resources. She spoke of deforestation, chemicals in the air, the waste and greed in our society, and the wanton destruction of animal and plant species that can never be brought back to life again.…

    The Endangered Species Act

    citizen that saving Earth's endangered species from extinction should be a national concern. Thanks to the press, over the years, a lot of people seem to have gained a general ethical and scientific understanding of the value of biological diversity. This biological diversity, or biodiversity, is a concept that emphasizes the fragile nature of the genetic and social interrelationships of the many varieties of plant and animal life that can be found in any given ecosystem (DiSilvestro, 1993). If one species vanishes, the entire ecosystem may be affected by the loss, in a possibly devastating chain reaction that current science does not presently have the ability to fully predict the outcome…
