I totally agree with Shola when it comes to alternative use of energy’s such as natural gases to coal but are these energy’s being misplaced. In our house at uni we recycle plastic, glass, paper, metal and have a compost in the garden, but there’s still an era of guilt when I hear the 6tonne lorry chug down the street collecting all the renewable materials.
I’m sure the recycling of tonnes of “rubbish” outweighs that of the pollution of the truck but I still can’t help but wonder how much pollution is caused through the collection of our do-gooderness. Some of the collection trucks along with London busses (RV1 to Covent Garden) are now powered by hydrogen fuel cells but not all of them are.
The notebook in Shoal’s blog looks quite tasty and is fuelled well but at what cost? Were the materials recycled such as the laptop Shola mentions after and if so were the materials sourced locally. Do we need more technology to write some notes down. The chalk and slate was abolished when paper was readily available but you could get more use out of a slate compared to that of several pieces of paper. Maybe in an instance like this we should go back and look at more rudimentary technologies such as the etch-o-sketch and save all sorts of materials without needing an energy source to operate them.
I was also intrigued at the statement that climate change also has a risk on the natural which is true don’t get me wrong, but what about the natural having effects on us. We as a species are predators and to fill this gap we have to make sure that there is enough to go around, but did you know that cows contribute more to climate change than cars do!! With a little of our help of course, the deforesting for grazing land, fertilizer being burnt off and of course cow fart, account for 18% of recent greenhouse gases. Stupid I know but if we (humans) were to vanish from the planet and all technology abandoned, C02 levels will still be contributed to at a rate the planet would still have a hard time handling.
We are the ones to blame for the situation we are in and many sacrifices will have to be made to counteract that, but I feel making new technologies such as note books powered with gas isn’t the way to go, I realise this is an example of what can be done with natural energy source’s but maybe we should step back and wonder if we really need some of the technologies we already have.
