Oh Christmas Tree, Oh Christmas Tree: Fake vs Real?

by Paul Davies

What's Going On Here?

Investing in a re-usable Christmas tree may seem more sensible than cutting down a real tree every year, but you would have to re-use the fake tree up to 12 times to make up for its carbon footprint.

What Does This Mean?

According to the British Carbon Trust, if a natural tree ends up as splinters for woodwork or burnt as firewood, it has a 3.5 kg CO2 carbon footprint. But, if a tree ends up decomposing in a waste dump, then its footprint significantly increases to 16 kg.

The carbon footprint of an artificial tree (often metal and PVC) is a whole lot bigger, reaching 40 kg of CO2, so it would be more sustainable to re-use it for at least 12 years, compared to a natural one which ends up as splinters.

Why Should We Care? 

Christmas trees are a big business, with over 80m used around the world each year!

The most popular type of Christmas tree in the UK is the Nordman fir. It takes about 10 years for one to grow up to 6ft absorbing CO2 as it grows, helping to keep its footprint down vs plastic. But if you bought an imported tree, such as a a Norwegian Ridgeback Spruce, then its carbon footprint shoots up because of shipping.

Be Curious!

So... when it comes to buying that tree:

1. Buy local & FSC certified
2. Buy with roots / potted
3. Plant in the garden and re-use next year. If you don't have a garden try a neighbour or the local wood!

(There are plenty of YouTube vids on re-planting Xmas trees, this one is fairly useless.. but we did find it funny)

Farming: Going Underground 

by Imogen Berryman

What's Going On Here?

Researchers at the University of Nottingham have patented a new system to tackle food supply security. Deep Farming, turning abandoned coal mines and tunnels into farms, has the potential to allow us to provide food in non-traditional ways.


What Does This Mean?

The name of the game is ‘hydroponics’ which simply means growing stuff without soil. 

Crops are grown in nutrient-rich water or suspended in the air and sprayed with water and nutrients. Artificial light in the form of LEDs is used to mimic photosynthesis. The method is expected to be used for crops such as leafy greens, herbs, strawberries, mushrooms, carrots, aubergines and others.
 
Here’s a curious.graphic to show what it can look like:

Why Should We Care? 

The global population expected to hit 9 billion by 2050 with most strain being on urban areas that lack space to farm.  One small deep farm can produce ten times more than on the same area above ground.  

These spaces also provide a controlled environment unaffected by climate and seasons, allowing year-round growing yielding up to eight more crop cycles. This means the technology could also be used in harsh climates.

And more, what a great use of those 150,000 abandoned UK coal mines. 

How’d ya like them apples? 

Be Curious!

Not only do local & seasonal veggies taste banging... but they don't have the air miles that Peruvian asparagus has!  

Trouble is the kids these days, unlike our elders, don't know their seasonal veggies

December:
Apples, Beetroot, Brussels Sprouts, Carrots, Celeriac, Celery, Chestnuts, Chicory, Cranberries, Jerusalem Artichokes, Kale, Leeks, Mushrooms, Onions, Parsnips, Pears, Potatoes, Pumpkin, Red Cabbage, Swede, Swiss Chard, Turnips, Watercress, Winter Squash.


p.s. check out our Instagram later this week for a seasonal recipe! @curious.earth.hq
