100% unapologetic about the title. A beautiful rendition of a classic four-year-old’s joke… Masterful. What do you mean “no”?… I was proud of that one!
London Wildlife Challenge day: We all lost count weeks ago, Tooby…
I spotted these lads on my daily commute to Turnham Green tube station. I believe them to be ‘Honey Fungus’ Armillaria mellea… Although they’re rather beautiful, these guys are a real pest, attacking the roots of woody plants, often leading to the death of the innocent host plant (such as the tree pictured here)… Bloody nightmare if you ask me…
A truly powerful video by a naturalist I love and trust since he correctly identified an enormous beetle that flew into my face (a good day, made better). Now is the time to find solutions to the problems and help our precious and yet severely depleted wildlife get back on track.
Happy #InternationalBatNight !! Help these chaps out by making your garden bat friendly! Follow the link below for tips. 🙂 Smashing…
Although plastic was invented in the early 1900s, it wasn’t until the early 1950s that the world really developed an appetite for this exciting and versatile new material (Cole, et al. 2013). Back then, global demand was just 1.5 million tonnes annually. These days we’re using some 322 million tons a year of the stuff (Cole, et al. 2013) – that’s a lot of plastic. Recently, the media has been buzzing with shocking stories about the negative impact on our oceans of all this plastic and one type of plastic waste in particular; ‘microplastics’ has really caught the public’s attention. But how big a problem is it?
There are several sources of microplastics, perhaps the best known being those purposely made tiny ‘beads’ that are used in commercial products such as toothpaste, exfoliators and laundry detergents. These get washed down sinks and drains and end up in our oceans (Cole, et al. 2013). Another source of microplastic pollution is the huge amount of tiny fibrous microplastics that are shed when we wash our clothes. One average 6 kg wash can release up to 700,000 microplastic fibres alone (Napper and Thompson, 2016)!
The second source of microplastic pollution starts life as larger forms of plastic such as drinks bottles, food containers, toys and utensils. Once discarded these are broken down into smaller and smaller fragments (plastics that are 5mm or smaller in diameter are considered microplastics) (Cole, et al. 2013).
The main problem with microplastics is that they take years to biodegrade (450 years for an average plastic bottle!) making them a serious and long-term problem (Jambeck, et al. 2015). If current production and management of waste trends continue as they are, approximately 12 billion tonnes of plastic waste will be in our landfills or the natural environment by 2050, of which between 5 and 13 million tonnes being tipped into the ocean (Jambeck, et al. 2015), a staggering statistic!
The effects of microplastics on the marine environment are still largely unknown, but what is known is that microplastic pollution is found across the globe; even in the remotest places like the polar regions and the deep ocean (microplastics have been recorded at depths of more than 500 meters) (Jambeck, et al. 2015).

It has recently been discovered that microplastics are ingested by zooplankton, which form the base of the food chain and therefore are carried on up through to the larger predators such as dolphins and even blue whales (Cole, et al. 2013). Researchers have even shown that microplastics can be ingested by humans through the seafood and shellfish we eat (Cauwenberghe and Janssen, 2014). The same study showed the average European consumer to be ingesting 11,000 microplastics annually (the potential effects on humans are not yet fully understood) (Cauwenberghe and Janssen, 2014).
With all this in mind, it’s crucial that we urgently find solutions to the plastic misuse issue. Industry must do its part of course, but It’s down to all of us to clear up our act; to get better at recycling, not buy plastic bottles etc and to change our thoughtless consumption of plastics to ensure cleaner oceans for future generations.
