LIFE IN THE UNDERGROWTH - Part5: Supersocieties (2005)

Successfully completed the wonderful wonderful series Life in the Undergrowth. Although my favourite episode of the series is the 3rd one named The Silk Spinners (mostly because of my love towards spiders), this episode Supersocieties is a very very special one because of the similarity to our society and these societies of superorganisms.

After watching this episode, you really feel that at some point of time there was some connection to us. I mean, apart from intelligence there are a lot of similarities between us and these superorganisms. (It is another matter altogether that by seeing some of the actions of our species, I some times feel that we are less intelligent than some of these invertebrates.)

At the start of this episode Attenborough states that "The superorganisms such as ants, bees or termites are not the blindly mechanical robotic slaves that we once thought they were, indeed we now know every insect society is full of conflict, power struggles & mutinies".

Power struggles & mutinies! I never thought that could happen in other species apart from ours.

So in this episode we go into these super societies to see how they work. There is one superb footage showing the rise (from scratch) of a bumblebee society, its functioning and finally its end when the worker bees revolt and kill the queen bumblebee.

The wood ants squirting Formic acid when threatened is another good shot. After a flood, the mud ants quickly saving their eggs and moving them to a higher ground is another thrilling sequence in this episode.

The specialty of this particular episode is that most of the sequences in this episode are like from a thriller movie. Check this clip and see whether this reminds you of an old James Cameroon movie.

LIFE IN THE UNDERGROWTH - Part4: Intimate Relations (2005)

In this 4th episode of the wonderful series Life in the Undergrowth, we are dealing with the relationships developed by the invertebrates not only towards their own kind but also towards plants. Most of us know that generally plants and insects depend on each other. But the kind of footage that they have shot for this episode is unbelievable.

This clip shows how a Gall wasp uses an Oak tree for the development of its egg.

LIFE IN THE UNDERGROWTH - Part3: The Silk Spinners (2005)

As the title says, in this episode of the Life in the Undergrowth series, we are dealing exclusively with the invertebrates which produce silk.

If you are thinking that spiders are the only invertebrates which produce silk then you are wrong because there are a whole lot of other beings which produce silk, of course apart from silk worms.

Check this clip to see the amazing fungus gnats, from the Waitomo Caves of New Zealand, building beautiful chandeliers to trap prey. This is a truly truly beautiful clip.

LIFE IN THE UNDERGROWTH - Part2: Taking to the Air (2005)

Since I've given a minute introduction to this series in my previous post, I will straight away give a few snaps from this episode.

As the title shows, here we deal with the invertebrates in air such as butterflies, dragonflies, wasps and a lot lot more.

There are a lot of metamorphosis videos shown in this episode but the best of the lot is the following one of a dragonfly. You wouldn't believe that the initial monster looking creature has changed into such a beautiful one.


LIFE IN THE UNDERGROWTH - Part1: Invasion of the Land (2005)

I've seen many programs about various wonderful forms & variety of lives on our beautiful planet. But until Life in the Undergrowth there hasn't been a program that dealt about invertebrates in such a great depth.

Narrated by the one and only incomparable Mr. Who Else, this is a series par excellence.

More than 95% of all animal species on Earth consists of Invertebrates. For every one of us there are more than 200 million of those. As David says in the following intro clip, if we backbone creatures disappear suddenly, everything goes on normally for them but if they disappear, we are going to disappear with them.

The following clip consists of the first 200 seconds of the program. Observe that at some level we do have some similarities.

How Many People Can Live on Planet Earth? (2009)

Do you know the following facts?
  • The current world population is just under 7 billion.
  • Every year 80 million babies are born.
  • Each additional being needs water, food & energy.
  • Already more than a billion people don't have access to safe drinking clean water.
  • A can of beer uses of 150 litres of water. Production of a cotton shirt takes 3000 litres of water.
These are some of the important facts shown in this programme.
Along with the brief description of the programme, I posted a few thoughts of mine below.


How Many People Can Live on Planet Earth? is an episode of BBC Horizon series & is narrated by the one & only, ever indefatigable Sir David Attenborough. In the programme David discusses about the affect of population growth on our ability to obtain food, water & energy. Also the danger to the environment due to rapid population growth is discussed. David also talks about the duty of individuals to commit to smaller families & to change the way they live for the sake of humanity and planet Earth. He makes an interesting but true observation which is although we humans do care about our near ones, thinking about our species as a whole was never our strong point.
