Scientists demand urgent action on reef mine plans

Scientists demand urgent action on reef mine plans | Australian Geographical Issues | Scoop.it
Australia's leading marine scientists demand governments take better care of the Great Barrier Reef just weeks from key UN meeting considering impacts of proposed coal and gas development at the world heritage site.
Clodagh Byrne's insight:

I agress with Australia's leading marine scientists, believing that governments need to take better care of the Great Barrier Reef. It is important that they consider the impacts of coal and gas developments at this world heritage site.

Spatial dimension: Great Barrier Reef, Australia.

Currently, tourism in the Great Barrier Reef generates $4.228 billion in Australia- a major money source to the Australian economy. With this however, over the past few years, tourism has also led to the damage of the reefs. 

"The Australian government adopted a water quality target which revolved around 'reducing human-cause imputs into the world Heritage Area of silt, nutrients, toxic pesticides, herbicides, and other toxic pollutants to as close to zero as possible.."

Scientists are demanding action with an increase to damage in the reefs. Being home to many unique biophysical processes, it is vital that action takes place to preserve these endangered and precious species.

Air quality in Sydney breaches safe levels 19 times

Air quality in Sydney breaches safe levels 19 times | Australian Geographical Issues | Scoop.it
Sydneysiders endured 37 days of high air pollution last year, with air quality breaching national standards on 19 days, says the NSW opposition.
Clodagh Byrne's insight:

I was very interested to find Sydney's record as the city with the dirtiest air in Australia, increased last year. I belive this record will continue to expand on a yearly basis.

Sydney's air quality has breached national standards has boosted our state's status as having one of the dirtiest air in our Country. (Far more dirtier than Western Australia) The Ecological Dimension for this case is the continual pollution of fossil fuels and the spatial dimension is occurring in Sydney Australia
Emma Khoury's curator insight, July 28, 2013 6:49 PM

Spatial dimension: Sydney Australia.

Last year, the Sydney air quality breached the national standards, with over 30 days of high air pollution. 

"Air quality was a major environmental and health issue in the Sydney Basin, with experts putting the cost to human health at more than $4.7 billion each year."

Many biophysical processes have been disturbed by this increase in air pollution in sydney, including that of crane flies (etc) , as well as contributing to global warning. Not only have wildlife been impacted by this air pollution, but human health is put at risk by an estimated $4.7 billion a year.

There needs to be some governmnent action to make sure that air quality levels are maintained under the National Air Quality Standards.

Five pieces of rubbish per person on our beaches

CSIRO survey highlights the proliferation of debris.
Clodagh Byrne's insight:

I found it very suprising that there are approximately five peices of rubbish per person on our Australian beaches, this is definitely a figuire we need to change!
