Global environmental problems HD

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.
