Fungi eats plastics and benefits environment

Fungi that eats plastic seems like a plot-twist right out of a sci-fi book or movie; however, this particular species of fungus which was found at a landfill site in Pakistan could be the real life solution to the ever growing plastic waste problem.

The Aspergillus tubingensis, is the species of fungus that researchers have found to feed off of plastic, breaking it down in weeks rather than years.

This is the not the first time finding organisms that feed off of plastic waste, as there were discoveries of bacteria that could break down plastic as well as the wax worm which can naturally degrade plastic due to its similar structure to that of its natural food, beeswax.

One of the reasons plastic had ballooned into the human substance of choice was because it was inert and therefore sterile. This meant that it could be used as ubiquitous as needed around the planet from food packaging to pacemakers to aviation.

However, the problem with plastics was the fact that they did not degrade easily , leading to  billions of tons of plastic still hanging around in landfills, and in the oceans , with more being added massive amounts of plastics in continue to be in production globally.

The fact that there are organisms ‘evolving‘ to exploit this new plastic –filled environment, has caused some researchers both a sense of excitement to study how they are doing so, but also some alarm  as well.

Scientists at London’s Kew Botanical Gardens reported that these organisms are an important advance in a world where momentum is building to reverse the toxic tide of plastic that is killing marine life and polluting the ocean.

Senior Kew Gardens Scientist Ilia Leitch, said that they are exploring these organisms for their potential to degenerate different types of plastic, explaining that “by understanding how the fungi break down these bonds and what the optimal conditions are, you can then increase the speed at which they do it.”

There are also other uses of fungi, including using it to feed on pollutants such as oil spills, toxic chemicals like sarin nerve gas, TNT and even radioactive waste.

The first-ever State of the World’s Fungi report, also spells out that advances in the agricultural applications of the various species of fungi could translate into improved food security, environmental sustainability and increased production revenues.

Climate change however, are affecting the the ranges of species of fungi and biodiversity in ways that the UN Environment (UNEP) revealed were still not fully comprehensible.

The fungi themselves are also under threat in high latitudes areas, especially where average temperatures continue to rise, such as the Arctic. These changes are already affecting fungi reproduction, geographic distributions and activity, with possible knock-on effects for our ecosystems.

“Species react differently to climate change, which disrupts the delicate interaction between them,” says Niklas Hagelberg, a UNEP climate change and ecosystems expert.

“This further complicates conservation; we need to quickly add climate change to our ecosystem management effort.”

 

 

Ontario needs to make conservation a priority

Have you ever been hiking on Manitoulin Island or in the Niagara Escarpment and paused for a moment to appreciate the ethereal beauty of the natural land?

Conservation is the only way to ensure that certain areas remain protected  in Ontario. The problem is that it is no easy feat to keep land from the greedy hands of major developers, and every single day more of these natural habitats disappears. Escarpment Biosphere Conservancy is a land trust that is dedicated to ensuring natural landmarks are conserved in the province. Unfortunately, the province of Ontario has removed their funding and this leaves the charity in a difficult position to continue protecting natural regions.

As a land trust, Escarpment Biosphere Conservancy accepts donations of land for conservation and also helps property owners to protect their own land from buyers. The conservancy is spearheaded by Robert Barnett, a passionate conservation advocate and architect by trade. The charity has 151 nature reserves making up 47 km altogether in the province. Biosphere focuses operations in the escarpment, but has several reserves across the province and is the second largest conservation charity in Ontario.

However, the charity has been facing roadblocks since their funding was removed in 2012. In that same year, the provincial government released a new plan called biodiversity: it’s in our nature to compliment Canada’s decision to sign a mandate towards conserving 17 per cent of Ontario land by 2020. The plan indicated that by 2020, “17 per cent of terrestrial and aquatic systems are conserved through well-connected networks of protected areas and other effective area-based conservation measures”. Four years later, conservation areas stand at 4.4 per cent.

“The minister announced this plan in 2012 and now of course nothing is happening. They aren’t increasing the land protected area at all,” Barnett says. “The premier has given the minister a mandate to protect our biodiversity and once again, nothing is being done. The environmental commissioner at the time, Diane Sax, recommended that they put funding into protected areas. This means the environmental commissioner, the premier, and the biodiversity initiative are being ignored.”

More than that, the province removed the charity’s funding the same year they introduced the new plan to increase biodiversity conservation. Previously, Biosphere received $30,000 to $40,000 in provincial funding to support operations at the charity. Now, Barnett can only rely on cash donations and limited federal funding for the projects.

“We spend $100,000 a year to protect the land, for legal fees and getting inventories done. It costs $5000 to receive a land donation because of appraisals and paperwork,” Barnett says. “That is a lot of money for a charity and we just don’t have it.”

Barnett believes that the funding cuts are in part due to the budget cuts the Ontario ministry of natural resources has experienced in the last five years. That being said, natural areas bring $84 billion to the economy and the conservation funding only costs $135,000. The Ontario government could easily fund such a low budget to complete such an important task.

One MPP is trying to make a difference for property owners interested in conservation. Eglinton-Lawrence MPP Mike Colle has introduced a private member’s bill to lower the property tax on private properties that place covenants protecting the land on their property. If a person owns a piece of land, they have the option to contact a land trust such as Biosphere to create a list of restrictions — known as covenants — to prevent future land owners from ever building a gravel pit on the land for example. In exchange for placing covenants on the land, homeowners receive a $100,000 tax receipt from Biosphere as a part of the land trust.

Placing covenants on the land lowers the property value, but the province continues to charge them the same property tax anyways. Colle has presented a bill to lower the property tax for conservation covenants to zero. The bill has had its first reading in 2012 and has since been stalled.  It is yet another example of the province not putting conservation of the land as a priority.

It is apparent that the province needs to pull up its britches and take conservation seriously. The fact that only four per cent of land in Ontario is protected when there is a mandate in place to have 17 per cent is unacceptable. The funding for Biosphere and other conservation charities needs to be reinstated and hopefully Colle’s bill will pass second reading and become law. Conservation doesn’t appear to be a priority — let’s make it one!
