Plastic not fantastic for birds

By 2050 it will be tough to find a seabird that hasn’t eaten plastic, predicts a new Australian study.

The research, published in the journal PNAS, assessed how widespread the threat of plastic is for the world’s seabirds, including albatrosses, shearwaters and penguins.
Researchers from CSIRO in Australia and Imperial College London combined data from studies going back to the 1960s, building an estimate of how many individual seabirds and seabird species were currently eating plastic.
The scientists estimate that 90% of all seabirds alive today have eaten plastic of some kind. This includes bags, bottle caps, and plastic fibres from synthetic clothes. Birds mistake the brightly coloured items for food, or swallow them by accident, and this causes gut impaction, weight loss and sometimes even death.
Based on current trends, the researchers predict that plastic ingestion will affect 99% of the world’s seabird species by 2050,
The worst affected area was the Southern Ocean boundary in the Tasman Sea between Australia and New Zealand, due to its abundance of seabirds.

Dr Matt Rayner, Curator of Land Vertebrates at Auckland War Memorial Museum, says the finding is not unexpected.

“The high concentration of affected seabird species around New Zealand may be surprising to the general public but not to those working in seabird conservation and research," he told the SMC.
"New Zealand is the global centre of seabird diversity with more endemic seabirds than any other country."
What can we do?  Dr Rayner did have some advice:
"First we should be concerned, as top predators seabirds are indicators of the health of our oceans and many of our seabird populations are not doing well meaning our oceans are not doing well. 
"On a local small scale level the public should become more concerned with the massive use of plastics in our everyday lives, on a global scale we need to be concerned that our politicians are engaged and concerned about such environmental issues as part of a global pollution mitigation strategy."

MBIE funding for NZ science

The Government has announced the recipients of the 2015 Ministry of Business, Innovation and Employment funding round, injecting $96.5 million into innovative and exciting research projects over the next four years.

Of a total 157 initial proposals, 48 research programmes were selected to be funded in the biological industries, energy and minerals, environment, hazards and infrastructure, health and society, and high-value manufacturing and services.

Funded projects include research investigating medical implants, insecticides, 3D printing, dairy goat infant formula, dental diagnostics, sensors, self-cleaning ceramic coatings, waterproof roads, family violence prevention and aquifer management.

“Research-led science is a key driver of economic growth," Science and Innovation Minister Steven Joyce said in a media release announcing the recipients.
"The Government’s science investment aims to produce excellent science that has the greatest capacity to benefit New Zealand."

You can read more about the funding and a list of successful applications on the MBIE website.

"It can affect your children and their future decisions that they have to make, it can affect the wider community...and I think when you choose to immunise your children, it's not just yourself you're protecting, but everyone else,"

How many trees on earth?

Three trillion, reckons a new study involving Kiwi researchers.

The new tree count is based on 400,000 measured tree density estimates from every continent except Antarctica, producing the most comprehensive global map of forest tree density to date.
The study also found that humans generally are not good for trees. While the total number of trees is higher than expected, it is only half as many as there were at the dawn of human civilisation, according to the new research published yesterday in Nature.
"Tree densities usually plummet as the human population increases," said Thomas Crowther, a postdoctoral fellow at the Yale School of Forestry & Environmental Studies and lead author of the study.
"Deforestation, land-use change, and forest management are responsible for a gross loss of over 15 billion trees each year."

Dr Susan Wiser, who manages Landcare Research’s National Vegetation Survey Databank, provided valuable data about New Zealand forests for the study.

She said the findings would be invaluable in managing climate change and guiding local, national and international reforestation efforts. 

Landcare Research general manager science Dr Peter Millard said it was important to have accurate numbers of trees across the globe in order to protect the precious resource.

“Trees are very important to us. They’re a major sink for carbon dioxide and source of oxygen. If we go on losing forests we’re in effect losing the lungs of the planet," he said.
