Environmental problems
endanger people's lives
The word environment means simply what
is around
What
doesus.
the word environment
mean?
The air we breathe,the soil on which we
stand and walk, the water we drink are
What
are of
parts
of our environment?
all parts
the environment.
The most serious
environmental problems are:
1. Pollution and its many forms
(water pollution, air pollution,
nuclear pollution).
2. Global warming .
3. Shortage of natural resources
(metal, different kinds of fuel).
4.
Destruction of wild life and
countryside beauty.
5.
The growth of population.
Water pollution
Nowadays pollution of water is a
very important problem.
Many rivers, seas, oceans are used
as dump for different industrial
and nuclear waste.
Many fish and sea animals are
poisoned. Some of them die, but
some can be eaten by people, who
can die or have different terrible
diseases or problems with their
health, too.
Global warming
The climate on the Earth
becomes warmer now. It is so,
because of the greenhouse
effect, which prevents heat
to go from the Earth into
space.
Some scientists say that
if the temperature rises
3-4°, life on the Earth
will be impossible.
Ozone layers
The atmosphere prevents
ultraviolet radiation to go to the
earth.
But today, as a result of air
pollution, there are some holes in
it. Through these holes
ultraviolet radiation can get to
the Earth and can cause
different skin diseases.
That's why we shouldn't stay for
a long time in the direct sunlight
Disappearing animals
The other problem is a problem of
disappearing of animals because of
bad ecology.
Many animals and birds are extinct
nowadays: dodo, passenger pigeon,
different reptiles, fish, and insects.
The main reason of their death is a man,
who kills them, destroys their habitats.
People hunted different animals for their
skin, meat. Many animals are endangered:
Indian tigers, African elephants, and
different kind of birds, fish, insects and
others.
The growing population
The Earth is 4,600 millions years old.
Modern man has lived on the Earth for only
35,000 years BUT, in that time, we have
changed our planet in many ways.
In the last 40 years, the population
of the world has doubled.
By the year 2200, it will probably be
10,000 million.
If we don’t change the way we use
energy and natural resources, we ‘ll
destroy our planet.
REDUCE IT!
A lot of the rubbish that we
throw away is not biodegradable.
We also produce a lot of
unnecessary things, such as
packaging.
We should avoid using nonbiodegradable material.
We should also reduce the amount of
unnecessary things that we produce
and consume.
International green
organizations
Nowadays people are worried about the
environment and try to solve environmental
problems.
They create different organizations such as
«Green Peace», «World Wild life Fond» etc.
The governments also makes different laws to
protect our nature.
We should develop international cooperation.
to be able to solve ecological problems together.
RECYCLE IT!
Every day we throw away millions of
tonnes of rubbish. A lot of this is
paper, cardboard, glass and metal
that we can use again. We should
find ways to recycle the things we
can.
Resist packaging!
Avoid heavily packaged products
Buy products sold in refill packs or concentrated
products
Reuse plastic bags or use robust shopping bags.
Resist consumerism!
Buy less - do you really need it? Can you use something
else?
Ask around - does someone have one they don't want?
Reuse things - adapt them for a new purpose!
Pass them on - to family and friends or to second hand
shops.
SAVE IT!
Many natural resources are not
renewable.
Coal, gas, metals and minerals, for example,
will finish one day. Other resources take a
long time to grow, such as trees, or are
not always available, such as water.
People should find ways to reduce
the amount of resources and energy
that we use.
We also have to find alternative
ways to make energy. We can use
the sun, the wind, the sea and the
heat of the earth.
This is our Mother Earth….
This is what it should look like!
