“Bartan Walaaaaaaaaaaaa”

You’ve Got a mail — If you are expecting Tom Hanks and Meg Ryan to exchange anonymous emails and fell in love again (reference American rom-com). You are mistaken.

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. …

Middle of November 2020, the spotlight was on the US president-elect Joe Biden’s announcement to re-join the Paris Climate agreement barely days after Donald Trump formally pulled out. On 17 November, an emerging Southeast Asian country caught the attention.

Vietnam’s National Assembly passed the revised Law on Environmental Protection legalizing carbon pricing and trading.

About Paris Climate agreement: It is a global pact forged in 2015 among countries of the world to avoid the worst impacts of climate change. …

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…

When someone refers to food-related videos, movies, or any food documentaries — what comes to your mind?

Most likely it will elicit memories of lip-smacking delicacies being prepared by a Gordon Ramsay’s of the world with all the finesse and sprinkling of the salt.

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.
