What’s Up There, Mother Earth?

22 Aug

A fuzzy looking earth?

Nope, this picture wasn’t captured when a cosmic storm passed through the solar system and decided to envelope Earth. Wanna take a second guess?

Those bits that you see hovering over Earth are satellites, all 6000 of them. They are the things that transmitted what you are reading right now (yes these very words) across the airwaves and allowing mass loads of data to be transferred via broadband connection across the globe every day. I don’t recall the Earth looking like this. The last mental image I’ve ever had was:

Quite a contrast isn’t it.

Even though there are 6000 satellites out there, only 800 are operational. Some of the bits are actually debris from collisions and accidents. Nobody is taking them down because it’s too expensive but somebody’s got to do it before the overcrowding causes more collisions in the future.

We’re not just junking up the Universe, here on Earth there are other wastes to consider. Every year, billions of mobile phones and computers go to landfills because of their high turnover rate. How often do you change your mobile phone and computer? Probably once every 3 – 5 years, typically, and you are not fully to blame. Technology changes so quickly that before your very eyes, Windows 7 will go out of the windows very soon;  4GB RAM will be laughable in 2 years’ time and people would have forgotten what an Intel processor is. Most of these electronic wastes we create contain elements of toxic such as mercury and lead, which can get into the soil and contaminate our waters. It will also endanger the lives of those workers at landfills and extra precaution have to be taken.

Will technology slow down, come to a peak and stay there? At the rate we are going, I doubt so but I also do not have the vision to see further than that. I just hope that as technology progresses, so will efforts be made at the same pace to ensure the sustainability of the Earth, for the sake of the next generation. Extend the shelf life of your purchases by buying smartly. Dispose of your computers and mobile phones responsibility and let not the toxic e-waste situation such as that in China continue.

Here’s some practical things you can do:

  • Dispose your old computers at a recycling centre
  • Dispose your mobile phones at recycling centre
  • If your electronics can still be used, give them away to Salvos cos it gets a new lease of life
