Transcripts
today we are going to discuss about the
fascinating World beneath our feet that
is soil and mineral resources like Fel
spass quarts micas olivines and amphib
bolts Fastpass are the group of alumino
silicate minerals that contain calcium
sodium or potassium quartz is a very
good combination of oxygen and silicon
micas that contain aluminium potassium
magnesium Etc then olivin are magnesium
ion silicate and amphiboles are
inosilicate minerals as the introductory
part of course we can start with the
soil and different types of minerals
there so soil and minerals might not be
the first thing that comes to mind when
we think about trash but they are
actually vital for our existence and
prosperity why we are concerned about
soil and soil minerals what are the
importance of soil and soil minerals how
are they treating us in various ways all
these questions can be answered in our
session so we can start with the first
question that is what is soil so it is
an interesting question it's very common
so many stories and informations are
available about it right soil is not
just dust it's a complex mixture of
minerals if people just see around your
world or around your feet then
immediately you can find the same thing
so it contains organic matter water air
and normal components of soil and it is
the foundation of life on Earth am I
right or not they are supporting plants
animals even humans and so so to some
extent we can refer an interesting
factor that is actually the origin of
humans Earth so that much importance can
be given to the soil again if we are
discussing the importance of soil the
soil cannot be
overstated it's the medium in which
plants grow providing them with
nutrients water and support so all these
contents are actually there in the soil
so they are the reservoir for all these
kinds of materials healthy soil they
also play a crucial role in regulating
water flow then filtering pollutants and
storing carbon however you know that
they are very interesting factors what
are the different kinds of functions
normally performed by the oil how do you
think that it is a comprising here so it
is under threat under threat you know
that is under threat it is everything
that we are saying that human population
or as any kind of animal population
plant population everywhere that we are
using the word threat threat here it is
the soil is also under threat from
various factors like erosion very common
there in nowadays pollution and over
usage if we don't take care of our soil
we risk losing its fertility and ability
to sustain life yeah it's all about soil
and then let's turn our attention to
Mineral Resources so that is our topic
let's discuss about mineral resources so
minerals they are building blocks of our
modern society used in everything from
constructions to electronics so normally
we are categorizing the minerals there
are two main types of mineral resources
the first one is metallic second one is
non- metallic normally we are discussing
about the factors abiotic and biotic
factors in the ecosystem so we are just
considering the same kind of idea here
also but not exactly and we are talking
about importance of the mineral Souls
here metallic minerals include gold
silver iron Etc actually there are so
many types of metallic minerals while
non- metallic minerals that include
Limestone gypsum salt and so on so it is
actually various chemical elements that
is the major problem here you know if
soil doesn't contain these kinds of
minerals or it contain something that we
are not going to be used then there is
no demand for soil unfortunately it is
comprised with these kinds of contents
and the problem is it's offer usage
everywhere everywhere that is happening
and it is actually very strong
economically these elements are very
strong giving more economic power to the
particular region or the nation so what
are the importance of mineral resources
mineral resources Es are essential for
economic development and technological
advancement we cannot refuse that they
are used in infrastructure projects
manufacturing processes energy
production so many so many applications
are there for these minerals so these
are not simple mechanisms either
infrastructure projects manufacturing
process energy production these are the
indicators of economy of the country may
be controlled by the mineral resources
so many examples are they since we are
clear about the potentiality of soil and
minerals we have the facility to extract
purify and use the soil and minerals but
there are certain kinds of serious
problems associated with it so-called
challenges challenges right however
mining for these resources can have
negative environmental impacts such as
habitat destruction air and water
pollution and greenhouse gas emissions
so everything is happening as a result
of this so-called
development we all are very wored with
these words environmental pollution
isn't it day by day we are hearing we
are discussing and we are writing about
environmental pollution everywhere then
again that we are are using another word
Environmental Protection Environmental
Protection but so far we did not realize
the real phase of environmental
pollution just imagine if you're working
kilometers for drinking water suffering
with polluted air fog appearance like
our Capital City these are just a step
door distance approaching us and it will
reach in our place very soon yes this is
reality where will we go then how can we
hide or escape from these crucial
effects of environmental pollution to
mitigate these impacts it's crucial to
adopt sustainable mining practices such
as reducing waste reclaiming land and
using renewable energy resources these
are several suggestions were made to
minimize the impact but practically it
is difficult to follow you know why
money we are utilizing all these
minerals for money we lost our thinking
capacity to take a wise decision to
whole system the policy makers the
supporters everyone but the real fact is
is we know we are in danger and waiting
for someone to help us so I concluding
here with the statement of soil and
mineral
resources they are invaluable assets
that sustain life and drive progress
it's our responsibility to protect and
manage these resources wisely for the
benefit of current and future
Generations thank you for listening
let's work together to ensure Ure a
sustainable future for our planet thank
you
