Shark of the week: Milne Bay epaulette shark — 14. May 2018

Shark of the week: Milne Bay epaulette shark

Epaulette sharks are cute, can walk and look all at first glance fairly similar. But if you take your time to look closer on those markings, you can find differences. Just like American marine biologist and author Scott W. Michael did, and he discovered that on some pictures and specimen of the common Indonesian speckled carpetshark the shark should not have those large and defined spots remarkably similar to the spots of a leopard. He informed his colleague Gerald Allen, and so, after genetic tests, in 2010 a new species of the genus Hemiscyllium off (the Milne Bay Province region of) eastern Papua New Guinea was named after him: the Milne Bay epaulette shark or Leopard epaulette shark (Hemiscyllium michaeli).

Like the majority of the other 8 species of its genus of the family Hemiscylliidae (Bamboo sharks or longtail carpet sharks), the up to 27.4 in – 69.5 cm – long Milne Bay epaulette shark is considered Near Threatened due to its small home range in shallow inshore coral reef waters with problems from overheating, overfishing and destructive fishing practices like dynamite fishing. Additionally, it suffers greatly from habitat degradation due to pollution and siltation from recent gold mining in the region (cyanide poisoning, river run-off and direct dumping of waste) and from ongoing logging and palm oil plantations. Producing and using palm oil not only endangers our air, our soil, our flora and fauna, out health and our atmosphere, but our oceans, too.

shark of the week: Broadfin shark — 19. February 2018

shark of the week: Broadfin shark

Another species of requiem sharks is the Broadfin shark (Lamiopsis temminckii). Living solely in shallow waters off India, China and Southeast Asia, it suffers greatly from habitat destruction, overfishing and water pollution. The IUCN considers this species as endangered.

Like almost all other requiem sharks, the Broadfin shark is viviparous. 4 to 8 embryos feed at first from yolk and later via a placental connection. After about 8 month they are born at 15 to 23 in -40 to 60 cm- length. Maximal length is 5.5 ft – 1.7 m.

National Geographic: study about plastic waste| Studie über Plastik-Abfall — 7. October 2017

National Geographic: study about plastic waste| Studie über Plastik-Abfall

Mass production of plastics, which began just six decades ago, has accelerated so rapidly that it has created 8.3 billion metric tons … 6.3 billion metric tons has become plastic waste. (Half of all plastic manufactured becomes trash in less than a year)… Of that, only nine percent has been recycled.

via http://news.nationalgeographic.com/2017/07/plastic-produced-recycling-waste-ocean-trash-debris-environment/

And this recycling can make matters even worse: In China fleece are made of disposable water bottles from Germany (as part of the recycling quota) and sold back to Germany, where they pollute the waste water and lastly the sea with micro fibers (microbeads) due to cleaning and still end up as waste, but already broken down in small particles (instead of after 450 years like the original water bottle).
Waste minimisation instead of recycling, I say!


Die Massenproduktion von Kunststoff, die erst vor 6 Jahrzehnten begann, hat sich so rasant beschleunigt, dass sie 8,3 Milliarden metrische Tonnen erschaffen hat… 6,3 Milliarden metrische Tonnen davon sind zu Müll geworden (Die Hälfte alles hergestellten Kunststoffs wird innerhalb von weniger als einem Jahr zu Abfall)…Davon sind nur 9 Prozent recycled worden.

via http://news.nationalgeographic.com/2017/07/plastic-produced-recycling-waste-ocean-trash-debris-environment/

Und dieses Recycling kann alles noch schlimmer machen: In China werden aus Einweg-Wasserflaschen aus Deutschland (als Teil der Recycling-Quote) Fleece hergestellt und wieder nach Deutschland zurück verkauft, wo sie das Abwasser und letztlich das Meer mit Mikro-Fasern (Mikroplastik) beim Waschen verschmutzen und doch wieder als Abfall enden, aber schon in kleine Teilchen zersetzt (anstatt nach 450 Jahren wie die originale Wasserflasche).
Müllvermeidung anstelle von Recycling, sage ich!

6 amazing plastic bans from around the world – and Germany? — 11. August 2016

6 amazing plastic bans from around the world – and Germany?

Good news! Plastics bans across the world have been hitting the headlines lately.From the US to India and Morocco, governing bodies are taking control of the plastic pollution problem, bringing in either complete bans on plastic, or bans on specific forms like polystyrene.

In Europe, we try to reduce the plastic waste, too, to protect the ocean from waste pollution. Especially the colorful plastic shopping bags the cashier throws at you for free. Every European uses 200 of them each year, most of them only once. But since the EU leaves it to their members how to do it, Germany uses its standard methods: personal commitment of the firms (freiwillige Selbstverpflichtung, that means they make a non-binding promise of their own to prevent a law) and money. Instead of banning these bags, the customer can use them further but in some markets he has to buy them first. Many markets offer canvas shopping bags, too, but they are more expensive. Guess what will happen?

I’m afraid it will end like with plastic bottles: instead of banning single-serving water bottles Germany put a deposit on them, just like on reusable PET bottles. And what happened? The quota of reusable water bottles decreased, of course. Many customers don’t differentiate between the two and use the lightweight single-serving bottle rather that the heavier reusable bottle, since it is all the same anyway.

Take the pledge and use no plastic shopping bags anymore – with time it becomes second nature to take your own bag with you (even if you have to interrupt the cashier in its routine to prevent getting another bag). And be proud about yourself for every disposible bag you don’t have used.

Every step counts.

Greenpeace about microbeads | Greenpeace über Mikroperlen — 23. July 2016

Greenpeace about microbeads | Greenpeace über Mikroperlen

Did you know that microbeads are used in cosmetics not only to exfoliate (which I can comprehend, even if they should use other, natural particles), but also simply for color and texture? Manufacturers seem to think that customers like their liquid soap, shower gel or shampoo smooth and thick (viscid), even if it has got no cleaning benefit and only environmental drawbacks. We use a special, ph-neutral liquid soap together with a reusable foam soap dispenser and it works fabulously. Sadly, my daughter likes glitter in her pink shower gel (girls 😉 ), I don’t know how to make that myself.

Greenpeace addresses the problem of microplastic in cosmetics here more detailed than I did and also describes the loopholes manufacturers use to deceive us. Unfortunately, the mentioned guide to avoid cosmetics in question seems to work only in UK and Australia.


Wusstest Du, dass Mikroperlen in Kosmetik nicht nur zum Peelen benutzt werden (was ich nachvollziehen kann, auch wenn sie andere, natürliche Partikel benutzen sollten), sondern auch einfach für die Farbgebung und Textur? Die Hersteller scheinen zu denken, dass der Kunde seine Flüssigseife, Duschgel oder Shampoo glatt und zähflüssig mag, auch wenn das keinerlei Reinigungs-Nutzen sondern nur Umwelt-Nachteile hat. Wir nutzen eine spezielle, ph-neutrale Flüssigseife zusammen mit einem nachfüllbaren Schaum-Seifenspender und es geht wunderbar. Leider mag meine Tochter Glitter in ihrem pinken Duschgel (Mädchen 😉 ), Ich weiß nicht, wie ich das selbst machen kann.

Greenpeace spricht das Problem von Mikroplastik in Kosmetikprodukten hier detaillierter an als ich es getan habe, und beschreibt auch die Hintertürchen, die die Hersteller nutzen um uns zu täuschen. Hier auch etwas dazu auf Deutsch. Bedauerlicherweise scheint der erwähnte Leitfaden zum Vermeiden von fragwürdiger Kosmetik nur in Großbritannien und Australien zu gelten.

Sources of Ocean’s Plastic Waste | Quellen der Meeres-Vermüllung — 18. December 2015

Sources of Ocean’s Plastic Waste | Quellen der Meeres-Vermüllung

Over half of the material leaked into the ocean comes from China, Indonesia, Philippines, Vietnam, and Thailand (Source). But that doesn’t mean that we others can slack off in our efforts to prevent plastic waste in the oceans – every step counts.


China, Indonesien, Vietnam, Thailand und die Philippinen sind die Quelle von mehr als der Hälfte des Plastikmülls in den Weltmeeren (Quelle). Das heißt jedoch nicht, dass wir anderen in unsere Anstrengungen, Kunststoff-Müll in den Meeren zu vermeiden, nachlässig werden dürfen – jeder Schritt zählt.
