Nanofoods

This week I want to put two of my little pets together. Nanotechnology and food might sound like two very different topics, like a cat and a gerbil to use the pet metaphor, but you would be surprised. Many products in fact have manufactured nanoparticles in them, and we eat them.

Now we might ask if this is safe, and some would say of course it is. Some have great reservations about it, and some point to the fact that there has been little research done into the matter and that it might be better not to eat them anyway.

Friends of the Earth US have recently published a report entitled Tiny Ingredients, Big Risks, and it is free to download here.

To give you a flavour of what is on offer, I just take a few lines from the report:

A ten fold increase in unregulated and unlabeled nanofoods over the last 6 years

Nanomaterials are found in a broad aray of everyday food (cheese, chocolate, breakfast cereals etc)

Major food companies are investing billions in nanofood and packaging

An increasingly large body of peer reviewed evidence indicates that nanomaterials may harm human health and the environment

Nano agrochemicals are now being used on farms so entering the environment

US regulation is wholly inadequate

Public involvement in decision-making regarding these problems is necessary

The products containing unlabeled nano-ingredients range from Kraft American Singles to Hershey’s chocolate. They are made by major companies including Kraft (KRFT), General Mills (GIS), Hershey (HSY), Nestle (NSRGY), Mars, Unilever (UL), Smucker’s (SJM) and Albertsons. But due to a lack of labeling and disclosure, a far greater  number of food products with undisclosed nanomaterials are likely currently on the market.

To give you an idea we are talking about silver, titanium dioxide, zink and zink oxide, silicon and copper, as well as the traditional carbon nano tubes that are found in food packaging and freshness labelling technologies.

The report documents 85 food and beverage products on the market known to contain nanomaterials — including brand name products, and points out that the nanofood industry will soon be worth $20 billion.

This is a detailed report, it lists the products that have been found to contain these materials, the health problems associated with ingestion of such materials in animals and calls for action. It does not make for light reading, but it appears to me to be a technology that is being sneaked in through the back door, and soon like genetic modification will be difficult to avoid.

Take a look back at my food series for more tasty stuff.

Deep Sea Mining Agreement

Time moves like molasses as they say here, but it moves.

Almost exactly a year ago I wrote a post called Mining the Seabed. Almost exactly a year before that I wrote a post about the possibility of sending robots to mine asteroids. All science fiction I heard you say, but oh wait.

A couple of weeks ago Nautilus Minerals, a Canadian mining corporation, signed a deal with the Papua New Guinea government to start digging (mining) the seabed just off their coast.

The mining will be done from the surface. A series of large machines (310 tonnes), one of which we see in the photo above, will be operated from ships, placed on the seabed and will effectively break up the top layer so that the ore can be pumped up as slurry (muddy stuff).

Now this doesn’t sound too good to me, but the operators claim that “It’s a resilient system and studies show that life will recover in 5-10 years. An active venting site 1km to the south East has the same bugs and snails and the current will carry the bugs and snails to the mine site. We expect it to recover quite quickly.”

Greenpeace don’t agree. The truth is we don’t really know who is right. What we do know though is that there is big money involved. The bed is rich in gold and copper, and we need this stuff for far more than wedding rings and rheumatism charms.

Now as some of you will know, my mission in life is to promote responsible innovation through my work at the Bassetti Foundation, and we can take a look at the developments above from this perspective. We all use gold and copper, and it is in great demand. My computer won’t work without electricity, copper cables, solder, silicon etc, so we can be as forthright as we like but we are the ones creating the demand.

Companies are looking to supply us and make a profit, there now seems to be a viable mining approach that will involve getting it from under the oceans. Nobody will be able to stop them doing it, so we need to think about how they are going to do it, and where.

There is probably no real way of knowing how quickly the seabed will reform or how much damage is going to be caused, there are no qualified experts in mining to conduct the operations (it’s a first time gig) and international regulation still needs to be drawn.

There does not seem to have been much public debate, we won’t be able to monitor proceedings ourselves and at the best of times, mining is a dirty affair.

So this could be a disaster waiting to happen, or it could be a fantastic opportunity to create a framework that could address all of the problems above and be applicable in other fields.

Last year some academics published an article about their experiences working in a geoengineering project. Similar set of problems as described above, but social scientists were involved in the project and participated in the decision-making process. The outcome was extremely interesting, the project scientists decided to suspend their research and rethink their positions. The article is free to download here, where there is also a more precise description. It’s easy to read and very interesting.

Earth Day

earth

Today is Earth Day. It is the 44th time that we celebrate this planet that we call home. The celebration started in 1970, and is the brain child of US Senator Gaylord Nelson.

Nelson asked Denis Hayes to organize a day of awareness, on April 22nd, and by the end of 1970, the U.S. Environmental Protection Agency had been established, and efforts to improve air and water quality were gaining political traction.

Today is a time of celebration, of love for our little speck in space. And it is a lovely speck, there are some quite beautiful places to see and experience dotted across the surface.

This year’s Earth Day boasts an organization that includes more than 22 000 organizations and hopes to conduct 2 billion acts of awareness and improvement. It is an education day, that has green schools and a Leadership Center.

Why not have a look at the organization’s website, and look around your little piece of the speck to see what you can do to raise awareness of the problems faced by our world and maybe plant a tree, collect some plastic for recycling, weed an invasive species or get into a debate with your kids?

There are plenty of opportunities!
