A Trillion Trees

Plant For The Planet, a global tree-planting movement sparked by a nine-year-old’s school project, has joined forces with the UN’s Billion Trees Campaign. They aim to encourage the planting of at least one billion native trees each year worldwide. In the first five years of the campaign 12,585,293,312 were planted and they are still going strong.

Felix Finkbeiner set the challenge to plant a million trees in his home country of Germany when he was nine years old, inspired by founder of the Greenbelt Movement Wangari Maathai, who he learnt about during a school project. Felix planted his first tree outside the gates of his school in 2007 and by the time he was 13 his message had spread and he was speaking at international conferences. That year, in 2011, the one millionth tree was planted in Germany.

The charismatic Finkbeiner, who is now studying at university in London, has inspired a generation of young activists to believe in their ability to influence change.


ā€œI knew he was this legendary kid,ā€ says Aji Piper, a 15-year-old tree ā€œambassadorā€ in Seattle who met Finkbeiner in 2015. Piper, an activist and plaintiff in a childrenā€™sā€™ lawsuit against the United States government over climate change, regards Finkbeiner as a role model.

ā€œWe saw he was doing speeches. He was so young. Very impressive. Thatā€™s the skill level I want to get to.ā€


The campaign also prompted the first global tree count, carried out by NASA, which showed that there are around three trillion trees on the planet, over seven times more than was previously estimated. However, with deforestation occurring at a rate of 10 billion trees per year, the coalitionĀ realised that they needed to up their goal from a billion to a trillion trees planted… and they took on the challenge, adding their weight to other tree-planting initiatives around the world.

Sustainable food production for 9.6bn people in 2050 is possible (if we eat less meat)

A study in Nature has shown that it could beĀ possible to meet the Ā nutritional needs of the predicted 9.6 billion people who will live on Earth in 2050, even without further deforestation.


A Western meat-rich diet provided the least number of viable future scenarios


The study modelled 500 different food production scenarios using regional forecasts supplied by the UN Food and Agriculture Organisation. It aimed to determine which scenarios would potentially provide sufficient food for the predicted global population.

Lead researcher Associate Professor Karl-Heinz Erb said:


“All the scenarios we have considered come with completely different ecological costs. Some of them have a high environmental pressure, and some of them have a lower environmental pressure, and we found that this is strongly determined by the diet.”


In the unlikely event of a completely vegan future, 100% of the scenarios modeled would provide sufficient food without expanding existing croplands and allowing for low-intensity farming methods such as organic farming. Vegetarianism also allowed for success in the majority of scenarios whereas the current Western meat-rich diet required high-intensity farming methods and a great deal of farmland expansion.


Feasability of various diets for sustainable global food production


Sustainable agriculture expert Professor Richard Eckard of the University of MelbourneĀ reviewed the study cautiously and pointed to several potential practical limitations of some of the scenarios. He pointed to the factĀ that naturalĀ grasslands such as the African Savannah are unsuitable for cropping and that livestock provide much of the energy for farming in the developing world. According to Professor Eckard, these are important considerations that were not accounted for in the study.
The authors of the study point out that it is only intended as a starting point for further debate.

Change your diet ~ Change the world!

Dietary changes in High IncomeĀ Countries could significantly contribute to more sustainableĀ global water usage, land use and greenhouse gasĀ emissions, as well as being healthier, according to a scientific review in PLOS ONE.



The review looked at 63 studies of diets which had both improved human health and reduced the impact of food production on the environment. It used agricultural land use, water use and greenhouse gas emissions as markers to assess the environmental impact of each diet.

Broadly speaking the review showed that shifting typical Western diets to more sustainable dietary patterns has the potential to produce over a 70% reduction in GHG emissions and land use and a 50% reduction in water use.

Based on all three measures, vegan diets would have the most positive impact overall, followed by vegetarian and then pescatarian diets. There was also a modest health benefit associated with all the types of sustainable diet studied.


Eating less meat is more sustainable


The authors also noted that most of the environmental impact of food is associated with the food production stage rather than the transport and delivery of food.


While local and seasonal diets have advantages such as protecting local economies and crop diversity, efforts to reduce dietary-related environmental impacts should focus on reducing animal-based foods in high-consuming societies.

Tiny homes as a solution to homelessness in NSW

TheĀ Tiny Homes Foundation (THF) has received development approval for a pilot project in Gosford, NSW. The project, which is possibly the first of it’s kind in Australia, hopes to combat homelessness with a ‘homes first’ approach, using tiny houses as an affordable, replicable solution.



The pilot project of four 16sqm homes, next to Gosford Hospital, will also include a shared living area, laundry and veggie patch. Each home uses solar efficient design, includes a full kitchen and bathroom and has a finished cost of less than $30,000.

The success of the project has been made possible by involving partners from diverse sectors. THF co-founder and CEO David Wooldridge says that whilst tiny homes themselves are ingenious, this project goes even further:


What makes the THF initiative groundbreaking is the fact that it is Council approved, low cost, replicable and features Australiaā€™s first ā€˜equity participation scheme for tenantsā€™ whereby accommodation payments not applied to the cost and maintenance of the project will be available to THF tenants as needed for future housing related expenditure creating a pathway from homelessness to self support.


Tiny Homes Foundation are offering all of their plans, documentation and processes free of charge to encourage others to replicate the project elsewhere across Australia.

Show me the honey: communication between birds and humans

A remarkable interaction between humans and birds in Mozambique is a win-win for both species, reports Karl Gruber in anĀ article summarising the recently published research of Dr Claire Spottiswoode on the ABC News Science website.

The study draws on earlier research by the Kenyan ecologist Hussein Isack in the 1980s. Isack showed that honey hunters were able to increase their harvests using information from small birds called honeyguides to help them find bees’ nests. The honeyguides have a vested interest in helping humans to find the hives because, once the hive is cracked open, they are able to feast on the eggs, larvae and beeswax within.

Dr Spottiswood’s research goes one step further by proving that the birds actively seek out honey hunters. The birds listen out for a specific call the hunters make whilst on the hunt.

It’s a startlingly odd noise, but our experiments showed that it works ā€” giving this sound doubled the chance of being guided by a honeyguide, and tripled the overall chance of actually finding a bees’ nest, so honeyguides really are paying attention to signals that humans communicate back to them.



There are relatively few documented instances of this type of mutual collaboration between humans and wild animals. Other cases in Australia include fishermen collaborating with dolphins and killer whales to catch fish.

Net Green: A more accurate measure of corporate environmental sustainability?

Using traditional life cycle assessments (LCAs) to measure the environmental impact of products and services is not an accurate enough measure and has become outmoded, according to Roland Geyer and Trevor Zink in a recent SSIR article describing a new measurement concept that they are calling ‘net green’.

Many current measurements, such as LCAs, assume that each ‘green’ product will replace a standard product one-for-one and that all other variables remain fixed, therefore reducing environmental impact.

The authors argue that a more efficient or ‘greener’ product may actually increase demand for, or usage of, a product. The net effect would therefore be an increase in consumption. They also point out that ultimately all products will have an impact on the environment. They challenge the very concept of a ‘green’ product or service.


Any corporate environmental communication strategy based on selling green products will always be plagued by the fact that all products have environmental impacts, and the greenest option will always be no product at all.


A more useful measure, according to Geyer and Zink, is to calculate the ‘net green’ impact of a product. This measure takes into account a whole gamut of possible impacts. These might include how consumers behaviour has changed because of the new product, which other products it is out-competing and whether the new product increases total market demand or product use.

This is clearly no mean feat. However, the authors believe that calculating ‘net green’ will be worth the effort for companies truly wishing to take responsibility for their environmental impact.


Embracing net green will make corporate environmental sustainability efforts more complex, but also more meaningful, rewarding, and defensible. It will also help companies enhance the credibility of their environmental communication efforts and avoid the hot water of greenwashing.

Putting people first in impact investment

Genuinely involving local peopleĀ inĀ impact investment can open up new investment pipelines and make for better outcomes for investors and communities, says Kelly Ryan from the US-based Incourage Community Foundation, in a recent article in the Stanford Social Innovation Review.

Incourage is a ā€œplace-based philanthropy, community developer, and impact investorā€ which has been working in a rural area of Central Wisconsin for over a decade. They are regeneratingĀ a local economy that was severely impacted by the sale of paper manufacturer Consolidated Papers in 2000. ThisĀ led to a 40% loss of area jobs within three years.


Involving community in impact investment


We are forging a new operating model as true community steward; advancing a long-term vision of inclusive community where residents and institutions are equipped with the skills, tools, and agency to shape the communities they want.


Impact investment can be much more than a top-down injection of cash into a community. Focusing on community involvement can diversify the benefits, creating a bigger bang for each invested buck.

Ways of working

Kelly mentions three ways that Incourage applyĀ this model within the community:

  1. StrengtheningĀ residents’ sense of ownership over the future of their region. Building community capacity by involving them directly in investment projects.
  2. Redefining people’s understanding of what has value in communities. Moving away from a purely financial capital mindset. Recognising and building on the social and intellectual capital of residents.
  3. Modelling values-aligned behaviour in their organisation. Discussions are then initiatedĀ on how this can be carried through in impact investments.



We have learned that an infusion of financial capital by itself does not yield behavior change and inclusive, sustainable economic growth. Change requires that we connect and leverage different kinds of capital ~ including moral, human, social, intellectual, reputational, and natural capital.


Local and Global

In order to have greater control over the way the wider economy impacts the community, Incourage also invest in and engage with companies who operate in their area to encourage business practices which have local benefits.Ā They also take careĀ to ensure that success is measured in terms of outcomes defined by the community itself as well as by global financial measures.

Doomsday Clock worsens to 2&1/2 minutes to midnight…

Itā€™s been 64 years since the world has been this close to Doomsday.

The Bulletin of the Atomic Scientists has been updating the Doomsday Clock regularly for 70 years. On Thursday, they turned the hands to two-and-a-half minutes to midnight.

Thatā€™s a bit closer than last year, when the clock was three minutes to midnight and the closest the clock has been to midnight since 1953 when it was two minutes to midnight. That move came following the U.S. detonating its first thermonuclear bomb and Russia detonating a hydrogen bomb.

Doomsday Clock

In the early days, the threat of nuclear war was the primary gear turning the clockā€™s arms. Climate change became a cog in 2007, moving the clock closer to midnight that year. Scientists invoked it in 2015 again, pushing the clock closer still to midnight.Ā And in 2017, another cog was added: a rising tide of political leaders around the world making statements unhinged from facts.

Climate change facts are clear: that Ā the world had its hottest year ever recorded in 2016, the third year in a row that mark has been set. Arctic sea ice has been decimated by repeated heat waves, seas continue to rise and researchers have warned of instability driven by climate shocks.

The cause is humanā€™s pouring carbon pollution into the atmosphere.

Carbon temperatures

ā€œFacts are stubborn things and they must be taken into account if the future of humanity is preserved,ā€ said Lawrence Krauss, one of the clockmakers and a professor at Arizona State University.

Yet despite knowing all of that, scientists have stressed that the world is not doing enough to put humanity on course to avoid catastrophic climate change.Ā David Titley, a professor at Penn State and one of the authors of the new doomsday clock report, said that while the Paris AgreementĀ represents a positive step, the climate talks in Morocco late last year didnā€™t move the ball forward enough.

While these actions weighed on the decision to move the clockā€™s hands closer to midnight, scientists also considered another disturbing trend of world leaders espousing policies and making statements not tied to evidence.

Thereā€™s no more stark example than the rise of Donald Trump in the U.S. He hasĀ espoused climate science denialismĀ as have many of hisĀ cabinet nominees and advisors. Heā€™s also made false statements onĀ dozens of topics, from voter fraud to the size of his inauguration crowd.

This is hugely problematic when it comes to climate change, where the U.S. stands as an outlier with the onlyĀ head of state to deny the scienceĀ behind it.

This is the exact moment when the world needs to be doing more to address climate change. Yet the current administration of the worldā€™s largest historical emitter is poised to ignore this fact, putting the future of humanity at risk.

ā€œNuclear weapons and climate change are precisely the sort of complex existential threats that cannot be properly managed without access to and reliance on expert knowledge,ā€ the scientists wrote in their report.

Scientists said they only moved it forward 30 seconds because Donald Trump has held office a few days. Thereā€™s still a slight hope his actions could be different from his words. If theyā€™re not, the hands of the clock may move even closer to midnight.
