Transcripts

The spread of consumer society is increasing demands and the quickening pace of life have

changed the relationship with nature.

The uncontrolled and rapid exploitation of natural resources has led to a downturn, in

long established global systems.

This has disrupted the once harmonious relationship between nature and human society.

This processes has led to local anomalies and regional differences.

The complex entirety of this local problems adds up to a global environmental crisis.

One of the greatest problems is the hunger for raw materials.

The rapid growth of the population and the emergence of new industries and services multiply

the demand.

However, our raw material and energy resources are limited, we will simply run out of them

one day.

The renewal of natural resources is a very slow process which can only be measured on

a geological time scale.

Today, we even mine minerals which were not considered worthy effort in the past.

Most of these can be accessed by opencast mining and these mines and their slag heaps

scar the landscape.

Apart from economising and recycling the widespread of renewable resources could represent a solution

to the problem.

The damage caused to the environment extracting and using fossil fuels makes renewable resources

even more important.

The atmosphere is worst affected by the pollution which results in the intensification of the

greenhouse effect and acid rain.

This type of pollution could be successfully reduced by the more efficient use of the energy,

and up-to-date technologies.

Another problem is the storing and recycling of waste materials.

If we collect certain materials selectively, we can save energy and raw materials as well.

Besides, discarded waste material is a huge burden on the environment.The manufacture

of the aluminium uses up to 3% of the total electricity produced.

Replacing the huge amount of aluminium cans requires a great deal of energies and raw

materials.

If selectively recycling were more widespread we would need to mine less bauxite for aluminium

production and fewer harmful gases would pollute our atmosphere.

Forests are among the Earth's invaluable Natural Resources.

Modern societies are destroying forests for a number of reasons such as: crop cultivation,

infrastructure development, road construction and the manufacture of paper.

Droughts and human negligence increasingly cause forest fires.

Agriculture is also badly affected by global warming.

Spreading desertification reduces the area of arable land.

The volume of water in rivers, and thus the water available for cultivating the land is

decreasing.

Furthermore, the over exploitation of the shrinking areas of arable land results in

a smaller yield and poorer quality of agricultural produce.

One of the greatest challenges today, and in the coming decades is the pollution of

the Earth's fresh water reserves.

Dangerous waste materials stored near river banks and lake shores are damaging their wildlife,

and surface waters pollute the seas and oceans.

Industrial pollution, fertilizers, pesticides, and heavy metals are endangering our freshwater

supplies.

Water waste is another global problem.

If we don't change our attitude to these challenges very soon restrictions will have to be introduced

in the water supply.

Humans are tiny creatures compared to nature's gigantic forces, so our future may depend

on our attitude towards nature and the way we utilize its resources sensibly, for our

own good.
