Its a moral question about whether we have the right to
exterminate species.
Sir David Attenborough (Wildlife Broadcaster & Naturalist), in
BBC interview
The control of nature is a phrase conceived in arrogance,
born of the Neanderthal age of biology and philosophy, when
it was supposed that nature exists for the convenience of
man.Late Rachel Carson (Marine Biologist & Conservationist), in
her book,Silent Spring
Living wild species are like a library of books still unread.
Our heedless destruction of them is akin to burning the library
without ever having read its books.
John Dingell (American Politician), in his book,Balancing on
the Brink of Extinction: The Endangered Species Act and
Lessons for the Future
I, Aryaman Mandhana, have decided the topic Ecological
Impacts of the industrial revolution & the need for
Conservation today as it scares me to think of what the future
holds for mankind. We have crossed all limits and forgotten
that we are only a drop in the ocean. Four human activities:
overharvesting of plants & animals, introduction of alien
species, destruction of habitat, islandisation and pollution;
have brought the threat of extinction for ourselves as race.
Even if we bring a catastrophic end to all present life, life will
not cease to exist on earth. Earth is very resilient and will be
here, and maybe after a million years, it will again be beautifulas it once was before mankind started destroying it. Only we

will not be here. We are not actually bringing the end of life
closer, we are only reaching out to the restart button of the
Gods. What a beautiful system,Karma.

1.1 The Sixth mass extinction: the pressing threat.
Earth is on the verge of the sixth mass extinction. A mass extinction is an
event, naturally occurring or otherwise, resulting in extinction of almost
all species living species. Such an event has been known by geological
studies, to have taken place five times since the formation of Earth (4.5
billion years ago). Previously, each time the cause was naturally
occurring. For example, meteor crash that wiped out dinosaurs from the
face of earth and allowed us Humans to evolve, the most recent and
better known mass extinction. Ironically and unprecedentedly, the
current threat of mass extinction is due to the activity of one species:
humans. I will try to explain these activities and take the industrial
revolution as an example to illustrate these problems.
Mass extinction due to naturally occurring reasons has been known to
take place over a period of time (the 5thmass extinction which wiped out
dinosaurs took place over 66 million years). But the 6thmass extinction
could even take place in a day, due to maybe nuclear world war 3? Or
maybe due to less drastic reasons, it would take more time, maybe
thousands of years. But it is going to happen; it may even be too late to
stop it. The only thing we can do is try to bring back the sustainable
balance of nature.
1.2 Sensitive & wise use of technology.
Now that we understand the pressing need for conservation, I would also
like to shed some light on other aspects. A major question that arises, are
we supposed to stop doing business, stop becoming more technologically
advanced, stop progress? The answer is no. We must always try to

improve, technologically and otherwise. It is human nature, to control,
to conquer. Technology is not to blame for the current state of our
planet. It is the use of this technology which has created the current
situation.
1.3 Earth is not abundant in resources & land.
But we can only take so much from nature. When man first went to
space, we realized that Earth, is not abundant in resources and land as it
seems to be. There will be a time when we will have no more land to
build houses, to cultivate food. We need to keep a balance, take only as
much as we need from nature. This does not mean stopping progress. If
we constraint ourselves to a limit where it is viable for nature to
replenish and sustain itself and simultaneously provide for us, we can
innovate more. Therein lays the challenge to todays innovators, to
innovate within these constraints.
1.4 Intrinsic value of nature.
Man only sees nature as a resource. What about the intrinsic value that
nature holds? It is the mother, of all life forms. The attitude that most
humans carry towards nature is disrespectful and will eventually be
taken care of by nature. We must be scared; we must thank and respect
our land for what it gives us. Once beautiful and biologically diverse
Earth is witnessing destruction of its bio-diversity at an alarming rate,
and will be converted to a barren cyber land as illustrated in science-
fiction movies like The Matrix.
1.5 What is the need for bio-diversity?
Earth is a system. If there are no other species but humans, we will
ultimately die as we cannot survive without food, shelter, clothing all of
which comes from either plants or animals. Natural processes dependent
on bio-diversity keep the planet healthy and full of life, thus making it a
better place for us to live.

H. sapiens(the adjectivesapiens is Latin for "wise" or "intelligent")arrived on the face of the earth around 200,000 years ago as non-
efficient hunters, yet to conquer the wild and flourish as a race. Since
then, we have never stopped evolving ourselves as not only better
hunters, but better scientists, better farmers, and so on. Today we have
the efficiency of killing species at a higher rate than they can reproduce
at, and hence we are, one by one, making species extinct.
Four major human activities are responsible for bringing us closer to the
sixth mass extinction event in Earths history. These are briefly
explained in the following sections.
2.1 Destruction of Habitat in Europe.
Agriculture first started around 10,000 BC, enabling man to become
independent of the ecosystem by growing food for itself. Now, it was
possible to sustain large populations. Since then, human population
never stopped growing, till date. Ever since the Industrial Revolution in
Europe, which took place between 1760 and 1840, humans have
becoming extremely efficient and capable of sustaining very huge
populations. This can be easily verified by looking at the human world
population growth curve:
Advent of agriculture theIndustrial Revolution, and more
recently, scientific and medical
advances have led to significant
rise in population growth.
Human population is growing
exponentially higher with
scientific and medical advances.

2.1.1 Agricultural Revolution.
One of the important events that led to the agricultural revolution, was
the invention of mechanical seed drill by Jethro Tull in 1708,
permitting large scale planting in rows, for easier cultivation between the
rows. At the time, seeds were distributed into furrows ('drilling') by
hand. Tull had noticed that traditional heavy sowing densities were not
very efficient, so he instructed his staff to drill at very precise, low
densities. By 1701, his frustration with their lack of cooperation
prompted him to invent a machine to do the work for him. He designed
his drill with a rotating cylinder. Grooves were cut into the cylinder to
allow seed to pass from the hopper above to a funnel below. They werethen directed into a channel dug by a plough at the front of the machine,
then immediately covered by a harrow attached to the rear. This limited
the wastage of seeding and made the crop easier to weed.
Crop yield increased, which meant that enough food was available for
people living in the cities. In Britain, wheat yields increased by about
25% between 1700 and 1800. Food prices fell, thus further fuelling the
Industrial Revolution as people had more money to spend on consumer
goods. Healthier Population meant decline in death rate, thus increase in
population rate. In the 18th century, the world human population
doubled from 5 million to 10 million.
Such a spurt in population led to increased need for food, housing and
other consumer goods. Thus, forests were cleared, to make land
available for agriculture, and for timber to build houses. Clearing of
forests is nothing but destruction of habitat of thousands of species that
make up a bio-diverse forest.
Agriculture not only directly effects the plant species that were cleared
to make land available for cultivation, but also animal species that were
directly dependent on the plants for their survival. Numerous examples
can be cited.

2.1.2 Advent of charcoal as fuel.
Pre 1709, wood had been the main source of energy in Britain, used forfuel in homes and small industries. But as the demand for energy
increased, coal, which has 3 times more power than wood, started being
used as fuel. Britain fortunately had plenty of coal mines to extract coal
from. In 1700, five-sixths of the world's coal was mined in Britain.
Digging of coals from mines requires clearing of all the forest cover
above the deposits.
2 .1.3 Deforestation: Destruction of Habitat.
Increased agriculture & usage of coal as fuel were the primary causes of
deforestation in 18th century England. Deforestation is destruction of
habitat and has adverse effects on bio-diversity. Such large-scale, long-
term ecological destruction has totally transformed the Scottish
Highlands, and now only around 1% of British native pinewoods remain,
while many other habitats have been degraded or lost. All of Europes
woodlands have been influenced by humans in some way and the
ecological effects have been complex and varied.
Some ways in which deforestation does this have been summarized in
the following paragraphs.
Even if an entire forest is not cleared, but only a part of it is to use for
cultivation, it creates a boundary in between the natural habitat i.e. the
forest. This effect is called islandisation and can have many adverse
effects on the biodiversity of that ecosystem. Now, it could be treated as
two different islands or patches, rather than one ecosystem. This is a
threat to many species in many different ways. One example is the silver
spotted skipper (butterfly) found in England. Due to islandisation, this
species becomes isolated to the land it is residing in. It cannot move to
another land as there would be a human induced barrier between its
natural habitat, thus making it very difficult for the butterfly to go into

another region. This makes mating difficult, and if there is a disease in
that area, those species cannot escape to a new region. Another example
is the Ant Bird, which depends on military ants for food. It follows
military ants wherever they go, but if the military ants run out of insects
to eat in a particular island of habitat, they shall simply cross over to a
new land, but unfortunately these birds cannot do the same as they are
psychologically used to dark shadowy areas of the forest. Thus are forced
to stay back and eventually die of starvation.
Not only has woodland cover been lost, but overgrazing in the remnants
has also selected out the most palatable species, especially aspen, holly,
rowan and juniper, which in turn affects the specialist species that
depend on them. Native woodland remnants are therefore less diverse
than they would otherwise be.
2.2 Ecological impacts of colonization.
As the Industrial Revolution increased yields by making industries in
Europe more efficient, there arose a need to find newer, bigger markets
to supply. Hence, Britain and many other European nations like Spain,
Portugal, Netherlands, all started colonizing markets and eventually
entire countries across the world. Many people like traders, managers,
government officials from these European countries were stationed life-
long at the colonies to conduct and control trade. For example, The
British East India Company in India.
2.2.1 Introduction of Foreign Species to colonies & vice-versa.
With foreigners, came foreign species too. Their domestic pets, for
example. Even vice-versa, taking exotic species from the colonies back to
Europe happened.
If an exotic species is introduced into a land of native species, it could
possibly have many advantages over the native species, as it has notundergone the ecological process of co-evolution with the rest of the

ecosystem like the native species has. This means that it could maybe not
have a predator to keep its population under control. Or maybe it is
simply faster than the native species and hence is able to thrive better on
the same land. It is directly or indirectly competing with the native
species for resources and land. Disease brought by exotic species, against
which the native species may not have immunity is another reason for
loss in bio diversity of native species.
2.2.2 Excessive hunting.
Colonization was more than just international business. It carried with
it a perverted attitude of superiority and racism. This can be clearly seen
by the activities of the British in India like the hunting of tigers for sick
pleasure and human slavery. During the British rule in India, animals
like cheetah, lion and tiger reached the threshold of extinction due to
excessive hunting, either for pleasure or for their skins/leather.
2.2.3 Examples.
Many examples can be cited where due to introduction of exotic species,
native species have ceased to exist and there has been great loss in bio-
diversity in those areas. The best example is the island of Hawaii. As
mentioned previously, the environmental impacts of human activities
can be best observed on islands. More than 90% of the native species of
plants and animals have been replaced by exotic species brought from
Europe by the British and Spanish in the 18thcentury. Another famous
example is of the Dodo bird, which was found only on the island of
Mauritius, became extinct due to excessive hunting and introduction of
pigs, which were brought to Mauritius by Europeans to eat. Pigs ate
Dodo eggs, thus these two reasons together drove the Dodo to
extinction.
Let us take up the example of extinction of Cheetah due to hunting by
the British in India into more detail. Due to the decrease in Cheetah
population, the deer population increases. This leads to overgrazing of
grasslands, which otherwise could have been used for grazing cattle.

Less area for cattle to graze directly effects agricultural yield. Sure,
cheetah may eat livestock and cause loss, but cheetah has equal right to
search for prey as we humans do. If livestock is managed and
maintained properly, this loss too can be easily minimized, as is being
done in Botswana. We cannot take everything for ourselves and leave
nothing for others. Eco-tourism can also be a potential reason to save
Cheetah.
2.3 Pollution.
Pollution is a major human activity contributing to the sixth mass
extinction event. Pollution refers to air pollution, by any gas that is not
present in the air at its natural amount. We will specifically discuss
carbon dioxide as it is the leading air pollutant, especially by industries.
2.3.1 Global Warming.
Global warming refers to an increase in average temperature of the
Earth due to increase in the carbon dioxide gas levels in the atmosphere.
Carbon dioxide, or CO2 traps the sunlight and thus warms Earth. It is
essential to maintain the temperature suitable for life on Earth. In the
past, due to naturally occurring events, the level of CO2 has fluctuated to
both extremes, thus causing mass extinctions.
Global warming poses a threat as many species will not be able to
survive in an elevated temperature. Also, it could result in melting of
caps and thus loss of land, floods in the polar regions. Remains of large
mammals have been found deep in the North Sea above Europe, thusindicating that this sea was once land.
2.3.2 London: The Big Smoke.
London was infamous for its combinations of smoke and fog, combined
in the word smog, and therefore earned the nickname the Big Smoke.
All major cities suffered from smoke pollution and Edinburghs
nickname, Auld Reekie refers partly to the sanitary situation of the
town as well as to smoke pollution. The effects of air pollution brought
-

cities to a halt, disrupting traffic but more dangerously also causing
death rates to rise. During a week of smog in 1873 killed over 700 people
in London. However, the largest air pollution disaster in Britain was the
Great London Smog of December 1952 which killed approximately
4,000 people.
Due to increasing industrialization in the 18thcentury & 19thcentury
England, there was a string of Parliamentary Acts in the mid-19thcentury
designed to do something about the polluting effects of industries and
domestic smoke.
Following the Great London Smog legislation was introduced and the
first Clean Air Act was passed in 1956 which moved power stations and
heavy industry to more rural sites. The reduction of domestic and
industrial coal burning and the use of smokeless coals has led to a
reduction in the levels of emission of sulphur dioxide, one of the main
contributors to acid rain, the emissions falling between 1970 and 1994 by
60 % in British cities. Similar developments can be observed in many
industrialised countries.
2.3.3 The impact of the Steam Engine.
The industrial use of steam power started with Thomas Savery in 1698.
He constructed and patented in London the first engine. It was not a
success as it could lift water up from very limited height and was prone
to boiler explosions thus rendering it unsafe for use.
The first successful and safe steam engine was made by ThomasNewcomen in 1712. A total of 1,454 engines had been made by 1800,
spread across Europe.
In 1775, James Watt made his steam engine which was very successful
commercially as it could be used to directly drive the rotary machinery of
a factory or a mill, a feature missing in Newcomens steam engines.

As you can see, the development of steam engines greatly boosted the
Industrial Revolution, especially in transportation: railway & ships.
Steam engines used coal to make iron, which was further used in making
machines, build bridges, railroads and ships.

As can be clearly understood from looking at the statistics on
environment depletion from the Industrial Revolution, industrialization
has majorly impacted bio-diversity and poses us with a threat of
extinction. The following are the conclusions and respective analysis I
have drawn from this research:
3.1 Technology needs to shake hands with Conservation
Only if every piece of technology built by mankind could be refined
keeping in mind conservation and the environment, the balance of
nature could be sustained. Using technology is not what is causing these
problems, it is the excessive use and unaware use of technology.
-
8/12/2019 Ecological impacts of Industrial Revolution
15/15
3.2 Technology must not be used without knowledge of use
Many farmers for example, would argue that they know very well how to
cultivate, if some conservationist tried to tell them the correct way of
using some equipment. This is not an ego battle that the conservationist
is trying to play. The conservationist may not know how to cultivate as
well as the farmers do, and the conservationist never hints at that. But
fact is that technology has been misused by humans out of greed or lack
of knowledge and this has in fact as we have seen from our study of the
Industrial Revolution, brought about many complex and varied impacts
on the environment.
3.3 Harmonious standardizing
I strongly believe that the farmer, the technologist, the conservationist
and the government should harmoniously come together to form a
platform that ensures standardized practices across the world. Just as
the farmer probably knows farming better than the conservationist so
does the conservationist know the environment better than the farmer.
It is not a matter of who knows more or who is important. That is theessence of conservation: nature is more important.
This not only applies to the field of agriculture, for every field of human
activity, most importantly industries. New innovations need to come up
under ecological constraints. This is missing today. When technology is
made, the environment is rarely thought about. Only later, does it come
into the picture if something wrong happens. If ecological constraints
are known to technologists, they shall from the beginning open
themselves to a different line of thought. This can only be achieved via
harmonious standardizing and coming together of conservationists,
technologists, users, and the government.
