Channel Deepening

Hey everyone,
no doubt everyone in or around Melbourne has heard about the channel deepening in Port Phillip Bay starting in Feb,here are some facts,
1/There are over 100 sponge species at the heads that can be found no where else on earth,there is a serious chance they could be lost(sediment covered)

2/Nitrogen balance is maintained by Benthic (seafloor)organisms,extensive areas would be covered,increasing the risk of toxic algal blooms.

3/Almost 4 million cubic meters of Yarra sediments containing heavy metels such as Cadmium,Mercury,Zinc,Lead,Arsenic & Ammonia will be dumped in the bay ,contaminants likely to re-enter the food chain,not to mention human risks to exposure.

4/An independant study of some mussels that were sampled & taken from the south end of the bay to the north end (Yarra) found over only a 6 week period that a significant increase in Mercury levels was recorded.The risks to Benthic fauna & potential for leaching of toxins has been grossly underestimated.

5/Bay related tourism provides around 1 billion dollars in benefits per annum & thats just the Mornington Peninsula,thats 10 times what the government hopes the channel deepening will produce annually.Channel deepening will have a negative effect on the economy threatening diving,fishing & bay tourism

6/The Port of Melbournes best estimate is that channel deepening would provide 1.9 billion to the economy by 2035 thats around 70 million per annum,similar to the annual value of the dive industry alone in Melbourne.

These are just some of the facts more info here if you feel compelled send Mr Garrett a message voicing your disapproval

Cheers everyone have gr8 long weekend
