Plastic might look harmless but every year millions of tons of plastic waste end up in landfills, rivers and oceans, wreaking havoc on our ecosystems. Whether it's plastic bags, straws, or packaging, our addiction to convenience is taking a toll on the health of our planet. But there is still hope. This Earth Day, let's commit to reducing single-use plastics, supporting recycling initiatives, and advocating for policies that promote a cleaner, healthier planet and reduce our plastic footprint significantly.

Hey All,

I've been away for some time, as we've been working really hard on something quite exciting:

let me present to you the world's first ever global ocean drainage basin map that shows all permanent and temporary water flows on the planet.

This is quite big news, as far as I know this has never been done before. There are hundreds of hours of work in it (with the data + manual work as well) and it's quite a relief that they are all finished now.

But what is an ocean drainage basin map, I hear most of you asking? A couple of years ago I tried to find a map that shows which ocean does each of the world's rivers end up in. I was a bit surprised to see there is no map like that, so I just decided I'll make it myself - as usual :) Well, after realizing all the technical difficulties, I wasn't so surprised any more that it didn't exist. So yeah, it was quite a challenge but I am very happy with the result.

In addition to the global map I've created a set of 43 maps for different countries, states and continents, four versions for each: maps with white and black background, and a version for both with coloured oceans (aka polygons). Here's the global map with polygons:

I know from experience that maps can be great conversation starters, and I aim to make maps that are visually striking and can effectively deliver a message. With these ocean drainage basin maps the most important part was to make them easily understandable, so after you have seen one, the others all become effortless to interpret as well. Let me know how I did, I really appreciate any and all kinds of feedback.

Here are a few more from the set, I hope you too learn something new from them. I certainly did, and I am a geographer.

The greatest surprise with Europe is that its biggest river is all grey, as the Volga flows into the Caspian sea, therefore its basin counts as endorheic.

An endorheic basin is one which never reaches the ocean, mostly because it dries out in desert areas or ends up in lakes with no outflow. The biggest endorheic basin is the Caspian’s, but the area of the Great Basin in the US is also a good example of endorheic basins.

I love how the green of the Atlantic Ocean tangles together in the middle.

No, the dividing line is not at Cape Town, unfortunately.

I know these two colours weren’t the best choice for colourblind people and I sincerely apologize for that. I’ve been planning to make colourblind-friendly versions of my maps for ages now – still not sure when I get there, but I want you to know that it’s just moved up on my todo-list. A lot further up.

Minnesota is quite crazy with all that blue, right? Some other US states that are equally mind-blowing: North Dakota, New Mexico, Colorado, Wyoming. You can check them all out here.

Yes, most of the Peruvian waters drain into the Atlantic Ocean. Here are the maps of Peru, if you want to take a closer look.

Asia is amazingly colourful with lots of endorheic basins in the middle areas: deserts, the Himalayas and the Caspian sea are to blame. Also note how the Indonesian islands of Java and Sumatra are divided.

I mentioned earlier that I also made white versions of all maps. Here’s Australia with its vast deserts. If you're wondering about the weird lines in the middle: that’s the Simpson desert with its famous parallel sand dunes.

North America with white background and colourful oceans looks pretty neat, I think.

Finally, I made the drainage basin maps of the individual oceans: The Atlantic, the Arctic, the Indian and the Pacific. The Arctic is my favourite one.

I really hope you like my new maps, and that they will become as popular as my river basin maps. Those have already helped dozens of environmental NGOs to illustrate their important messages all around the world. It would be nice if these maps too could find their purpose.

The saltwater crocodile has the strongest bite force ever recorded in a lab, thanks to their massive and extremely stiff jaw muscles. These muscles are specifically designed to clamp down, but they're not as well suited for opening the jaw. A saltie's mouth can be held shut with just a few layers of duct tape! ©NatGeo

Fish of the Day

Today's fish of the day is the Alabama Cavefish!

The Alabama Cavefish, scientific name Speoplatyrhinus poulsoni, is known for being one of the rarest troglobitic fish species in North America. Discovered in 1967, by the time the alabama cavefish was scientifically described in 1974, there were only about 100 fish left. On any visit to the cave, only about 10 fish have ever been seen, but they are consistently different fish, so the estimated number is a little under 100, making them critically endangered. This also makes them a possibility for the rarest cavefish in North America!

Despite the large waterways connecting caves in Key Cave National park to several other cave systems, the Alabama cavefish has restricted itself to only one cave for reasons we don't understand. A search of over 120 caves in the surrounding area revealed no populations or signs of populations. With a range consisting only of Key cave in Lauderdale county, Alabama; these fish are constantly faced by the threat of extinction, and most of their worries are based on the limited home range, and waters entering the cave. Any water with chemicals, especially fertilizers and other agricultural runoff are a large concern. That along with competition from more aggressive cavefish, and predation from nearby crawfish. Due to their living situation and delicate population, much is unknown about these fish. But, let us go over what we do know!

The diet of the Alabama cavefish consists mostly of invertebrates found in the caves: copepods, isopods, smaller cavefish, spiders, beetles, and anything else it can find that will fit in its mouth. They grow up to a size of 2-3 inches in length. They have no eyes or pigment, and hunt solely based off of sensory protrusions that dot the head and sides, a trait evolved to handle the almost complete darkness. These fish have no breeding season, and instead breed based off of the environmental signal: when the caves flood in the winter and spring. Insufficient flooding can lead to years where no breeding or spawning occurs, and when it does females carry few eggs, and even fewer eggs hatch. Their lifespans, based off of the lifespan of Northern cavefish, are an estimated 5-10 years.
