President Jacob Zuma says ‘Frack You’ to Karoo

The process that will be used to extract the gas – hydraulic fracturing, or ‘fracking’ – is carried out by drilling deep into the earth and injecting hundreds of millions of litres of a high-pressure mixture of water, sand and chemicals into shale rock, which in turn releases shale gas. The flow-back liquid from this process is highly radioactive.

Make Pinnacle a heritage and eco-tourism site

The history of Rastafari in Jamaica is marred by not so sweet stories. Nevertheless, sweeping it under the rug does the country no good and clearly says “Jamaica is still ashamed of Rastafari”. While the Jamaican establishment laments Rasta’s lack of political mobilisation and the fact that they often operate on the fringes of the economy, there is no denying the deep cultural impact they have had on the island.

Environmental implication of Joburg’s mining history

The epicentre of the tremor was said to be beneath UJ’s Auckland Park campus by the Council for Geoscience but Dr van Niekerk suspects that a more accurate analysis would find the tremor started at a nearby mine shaft.

“It is very difficult to come up with an epicentre because it takes a lot of reading data, but there are no old mine shafts underneath the university itself so it is highly unlikely. UJ may just have been used as it is a recognisable landmark. Now, if you go just over Brixton hill to the southern side of Brixton Ridge, there are many abandoned open mines. If these mine shafts collapse, they will obviously cause the place to shake.”

Why we need trees

The trees in our suburbs serve many purposes. They beautify our communities and release oxygen while offsetting carbon dioxide. They also moderate the climate by regulating the effects of the sun, wind and rain. What’s more is that trees and the soil they root in help to absorb run-off water associated with stormy weather.
