TED Talk: Garbage Island


Did you know....that there is a floating island of garbage in the middle of the Pacific Ocean TWICE the size of Texas??

“Researchers believe this enormous trash zone accumulated over many years from trash being dumped off boats and ocean-going ships, and from trash accumulated on beaches, where it eventually washed in the Pacific Ocean and into the huge zone.” - CNN.com

The accumulation of rubbish stretching from California, Pacific Islands to Eastern Asia is brought to this isolated ocean patch in the Pacific through the wave currents. 80% percent of the trash originates on land from all areas of the world! So what are the facts?
  • 90% of all trash floating in the world's oceans is plastic
  • About 10% of more than 200 billion pounds of plastic the world produces each day ends up in ocean
  • In fact every square mile of ocean contains 46,000 pieces of floating plastic

The main problem with plastic - it does NOT biodegrade! which means that no natural process can break it down! [watch the video "Story of the bottled water" on my previous post to see how we are currently consuming and producing more plastic bottles every day].

What are the implications of all these plastics floating in the ocean?
  • Albatrosses - constantly mistaken all kind of plastic as food. Resulting in 200 out of the 500,000 chicks died every year by consuming plastic given by their parents
  • Large chunks of plastic found inside hundreds and thousands of dead birds!
  • Small fish in the ocean (like the dead Nemo seen in the video below) are eating these plastics - which raises the question - Are we also eating these little plastics inside the fish that we consume?
  • In total, more than a million birds and marine mammals die each year by consuming or becoming caught in plastic and other debris in the ocean that we all produced.


So what can we do? - cleaning up the Garbage Patch that expands the area of a continent and extends 100 feet below ocean surface is simply IMPOSSIBLE. 


Changing our behaviour and lifestyle is our only hope.
  • Paying attention to how much packaging involved in your purchase and don't forget to recycle!
  • Support companies that support environmental protection and decisions to be green
  • Lobbying large companies to find alternatives to plastic to a more environmentally-safe, reusable packaging 
  • Educate others about the importance of recycling plastic and be more conscious in what you are dumping.
For us planners?
  • Provide incentives to companies that are more environmentally-friendly
  • Educate the public through green campaigns and eco-events [like in my "University of Auckland Eco-Fest 2011" previous blog post]
  • Hold community volunteer days such as beach clean-up days
  • Ensure effective recycling programs available to all cities and towns

These are just a few small, simple things that we could do. Planners and politicians hold a relatively high power in decision-making processes affecting our regions - therefore it is our responsibility to ensure that environment protection and sustainability are on top of our list!


"The food we eat, the air we breathe and the water we drink is all impacted by the environment and what we dump in it."

Auckland University Ecofest 2011 & Shark Finning in NZ

On the week starting Monday 16th May - Friday 20th May, AUSA at the University of Auckland celebrated EcoFest Week with various stalls, events and lectures held around campus. I went to have a look at the Ecofest week to see what they have to offer and I ended up learning quite a few things! So here is what I learnt from Ecofest:
  • Vegan food isn't all  that bad! Free vegan lunches were available throughout the week and it was delicious
  • It is possible to make your smoothie in a more sustainable way through a bicycle-powered smoothie maker. So yes. you can burn calories before you even drink your smoothie!
  • Ways to save money at the flat! I learnt there are so many simple ways to maximise energy efficiency and water minimisation such as through wrapping  your hot water tank in blanket or installing rain water tanks at your house
  • It is possible to go rubbish free for one whole year at your house! A couple in Christchurch has successfully done this - I will further discussed this in my next blog.
  • I even signed up for a petition and emailing list on an issue that I never knew about - Shark finning in New Zealand. This will be the main issue in this post:
Did you know..that humans kill 100 MILLION sharks per year? and for what?


  • shark fins for a tasteless bowl of soup
  • shark teeth for jewelry
  • shark jaws for tourist souvenirs
  • shark skin for leather wallets/belts
  • shark cartilage capsules and powders for phony medicinal cures
  • shark liver oil for cosmetics/skin care products
With the movie Jaws and other Hollywood blockbusters,sharks are one of the world's most misrepresented creatures. With 90% of the world's large shark populations already wiped out - they're in trouble of being lost from our oceans forever.

So why is finning still allowed in NZ?
NZ has 112 species of shark recorded in our waters but according to World Conservation Union (IUCN) - only one threatened shark species - The Great White Shark is protected. On average 24,000 tonnes of shark are caught each year in NZ according to Ministry of Fisheries - the equivalent of 300,000 people. 

What can you do?
  • Join 7000 other New Zealanders and make the shark fin pledge here: https://secure.forestandbird.org.nz/pledge/sharkspledge.asp
  • Never eat and vocally oppose to shark fin soups selling in restaurants - a local example is the Grand Harbour Chinese Restaurant in Auckland's Viaduct! Demand that they stop.
  • Educate others the importance of sharks to the ecosystem
  • Watch the award-winning documentary Sharkwater and encourage others
  • Develop new perspective of sharks!
Myth : Sharks are bloodthirsty man-eaters and ruthless killing  machines (as seen in Hollywood movies)
Reality: More people are killed each year by falling vending machines than by sharks
