“Bartan Walaaaaaaaaaaaa”

In a study conducted at the Massachusetts Institute of Technology (MIT), the researchers discovered a mechanism whereby plants can send out alerts.

Spinach, which was used for the research, was fitted with carbon nanotubes (tubes many times narrower than a hair). This transformed the spinach plants into a sensor that can detect chemicals in the soil and nanotubes send a signal. …

What a year it was, 2020 will be forever etched in our memories and will be passed on to the next few generations, unless something even more dramatic happens.

While the world started hearing about some disease in some corner of China, no one really bothered in the first couple of months of the year. Then suddenly even before any of us could react, the virus engulfed the world, quite literally.

The jury is still out if the virus was man-made or nature-made, but the 2020 experience is going to shape our behavior at least for the next foreseeable future…

Inevitably we have to select a product where we don’t have any control.

If you look at a laptop, there are 5 broad areas that we need to consider from an environmental conservation perspective (as such it is true for most products).

  1. Transport and Logistics — moving the raw materials to the manufacturing & assembling facilities, taking it back to storage centers & retail stores, delivery to the consumer.
  2. Manufacturing & assembling — electricity consumed while manufacturing & assembling, materials & components used for making the laptop
  3. Packaging — All the materials used to keep the laptop safe, and to get it delivered to the consumer.
