We tend to think of the overuse of natural resources, climatic instability, and large-scale human land use as quintessentially modern day problems. Yet a group of researchers led by archaeologists and calling themselves historical ecologists have recently come together to determine what we need to know about past human-environmental relationships to build a more sustainable future. These historical ecologists crowd-sourced hundreds of research questions from scholars around the world that, when answered, will reveal key information about how people have hade impact on and responded to changing environments over the course of thousands of years. Workshops were held at Uppsala University (Sweden) and Simon Fraser University (Canada) to discuss submissions from scholars and identify the 50 questions that are most in need of answering. The list of 50 priority issues for historical ecology will be published Friday in the open access journal PLOS ONE.

New use for paper industry's sludge and fly ash in plastics
VTT Technical Research Centre of Finland examined, as part of the EU's Reffibre project, whether new industrial applications could be developed for various types of sludge and fly ash generated by the paper and board industry. Laboratory tests showed that these side streams can replace up to 50% of oil-based polypropylene. They can be used as a raw material in plastic composites made using injection moulding and extrusion.
Forests to play major role in meeting Paris climate targets
Forests are set to play a major role in meeting the objectives of the Paris Climate Agreement - however, accurately monitoring progress toward the 'below 2°C' target requires a consistent approach to measuring the impact of forests on greenhouse gas (GHG) emissions.
In a paper published in the journal, Nature Climate Change: Key role of forests in meeting climate targets but science needed for credible mitigation, scientists are calling for robust, transparent and credible data to track the real mitigation potential of forests.
Coming soon: Oil spill-mapping swarms of flying drones
Inspired by bird and insect behavior, engineers create software to enable teams of common UAVs to work together
Thousands of ants converge to follow the most direct path from their colony to their food and back. A swarm of inexpensive, unmanned drones quickly map an offshore oil spill.
New polymer additive could revolutionize plastics recycling
When Geoffrey Coates, a professor of chemistry and chemical biology at Cornell University, gives a talk about plastics and recycling, he usually opens with this question: What percentage of the 78 million tons of plastic used for packaging – for example, a 2-liter bottle or a take-out food container – actually gets recycled and re-used in a similar way?
The answer, just 2 percent. Sadly, nearly a third is leaked into the environment, around 14 percent is used in incineration and/or energy recovery, and a whopping 40 percent winds up in landfills.
What's The Leading Cause Of Wildfires In The U.S.? Humans
Wildfires can start when lightning strikes or when someone fails to put out a campfire. New research shows that people start a lot more fires than lightning does — so much so that people are drastically altering wildfire in America.
