On the 16th of September it was World Ozone day. Greenhouse Malta held an online campaign spreading over 5 days to commemorate this day. The campaign will stay open throughout the year as we feel that we should work throughout the year for important issues.

We thought to use something fun to spread the message that although it seems that the ozone hole is not increasing anymore and the layer is becoming ticker the problem is still there.

We wanted to raise awareness on the fact that what we do does not affect only us but it has affected agriculture, other creatures and organisms and of course us and our health.

We also wanted to raise awareness on the fact that because it happened once it could happen again and on any issue that whatever we do is not just out problem anymore because it affects the whole ecosystem.

The increase in the UV has affected mainly marine organisms and so we wanted to have this campaign where we do origami, that’s right, origami of four different marine creatures that were affected by UV.

We created videos which we put up on youtube on how to make origami of frogs, shrimps and fish; with the first two having versions in both Maltese and English. Originally we also wanted to include crabs, but we saw that participation was low possible due to the difficulty of some of the origami. The fish, which was the last origami, was only filmed in English because we realized that most people were watching that. We included the Maltese versions of the first two tutorials because we feel that Maltese is being forgotten and we also wanted to target people in Malta that do not know English. We included subtitles for people that have visual difficulties, however, we realized how difficult it is to give instructions that are coherent without showing what you mean. Overall, it was also difficult to film two videos, transcribe and then set subtitles- especially the Maltese ones which had to be done manually.

We are happy that for our introductory video we also had someone that volunteered to translate the text into Spanish for the campaign. Big thanks go to María Martínez Ruiz and the Spanish network Red Equo Joven.

The idea was to make tutorials on how to do some origami of marine creatures, then invite people to upcycle some paper (to be green) to make these origami and then share them on social media along with a fact on ozone.

Although participation was low, we now have materials for a longer campaign, so please share with your friends, watch our videos or other tutorials and participate using the hashtag #GreenhouseforOzone

Here under are some photos that were shared with us along with the fact.

A diminished ozone layer allows more radiation to reach the Earth’s surface. The consequence is overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems. Increased UV can also lead to disruptions in the marine food chain.

Noelene Scerri (Malta)

If the ozone layer was brought down to the Earth’s surface, air pressure and temperature conditions would compress the ozone into a layer 2 to 5 mm thick.

Extra ultraviolet B radiation reaching Earth also inhibits the reproductive cycle of phytoplankton, single-celled organisms such as algae that make up the bottom rung of the food chain. Biologists fear that reductions in phytoplankton populations will in turn lower the populations of other animals. Researchers also have documented changes in the reproductive rates of young fish, shrimp, and crabs as well as frogs and salamanders exposed to excess ultraviolet B.

If ozone-layer depletion reached 15% over temperate waters, it would take less than five days in summer for half the zooplankton in the top metre of these waters to die from the increased radiation.

Because UV-B radiation is absorbed by only a few layers of cells, large organisms are more protected, whilst smaller ones, such as unicellular organisms in aquatic ecosystems, are among the most severely affected by UV radiation.

In 2009 the Montreal Protocol, the legal instrument that made possible the International response to the threat of Ozone depletion, became the first International Agreement to gain universal ratification, that is ratification by 196 Governments.

Phytoplankton which is affected by the depletion in ozone, is the basis of the marine food web and a reduction in productivity would affect dependent species such as krill, fish, penguins, seals and whales.

The increase in UV due to Ozone depletion may have lethal affects on amphibians.

If ozone-layer depletion reached 15% over temperate waters large amounts of young fish, shrimp and crabs would die before reaching their reproductive age.

Ozone (O3) is the unstable form
of oxygen. It only has three atoms. Unlike oxygen which has two (O2).

Mina Tolu (Malta)

UVB destroys small phytoplankton in the Antarctic ,contributing to global warming and a collapse in the polar and sub-polar oceanic food supply. Global warming causes a collapse of the zooplankton in the temperate and equatorial oceans, further contributing to the collapse of the oceanic food chain.

We also had a facebook event where almost all photos where uploaded.

Our videos could be watched on our playlist.

Our Green Consumerism blog posts will be up again this weekend!
