27 New Animal Species Discovered in Tanzania

You can add this to one of the reasons why Tanzania is such a special place.

This article from Tanzania’s Daily News online paper outlines the discovery of 27 new species, most of which are reptiles and amphibians. The collaborative effort between the Tropical Biodiversity Section of the MUSE-Science Museum in Italy and the Tanzania Forest Conservation Group shows just how unique the Eastern Arc Mountains are – the Ulugurus, the Udzungwas, and the Usambaras. (They also have fantastic names!)

Not only do these tropical forests harbor a large number of endemic species, they are critically important in maintaining freshwater resources that people depend on for agriculture and domestic uses such as cooking, bathing, and drinking. This link exemplifies why the protection of habitats – and not just a focus on individual species – is so important. If we take a holistic, big-picture approach to resource conservation, many of the associated issues in development become more manageable: more people have more access to cleaner water, meaning that improved personal hygiene and sanitation lead to lower medical costs. Simultaneously, when coupled with sustainable management of soils, food security improves, leading to the economic growth of farmers’ livelihoods. Higher levels of biodiversity in protected areas often also mean an uptick in tourism and the revenue that generates for both local communities and national governments.

The conservation of biodiversity in the context of a developing country like Tanzania is a tricky, complex process involving myriad factors, all of which are changing rapidly. If the answer were simple, the problems mentioned above would have been solved decades ago. I just hope that the people making those decisions can find a way to sort it out before we’ve lost it all forever – the forests, the species, and the livelihoods.

Putting All The World’s Water Into One Big Box

I was researching something about evolution for one of my grade 9 classes the other day when I stumbled across this series of infographics about water resources. We’ve just begun our exploration of Topic 2 – Ecosystems, but these infographics do a really nice job of putting the amount of water on our planet into perspective. You can click on this link for the original post at waitbutwhy.com.

We will revisit these images when we dive into Topic 3, Subtopic 3.6 – Water Resources (‘dive in’ – get it? haha!), but they’re worth a read now. You’ll need to know some of these numbers for your IB Exam!
