Global issues

Enviromental problems

Most of us worry about different kinds of problems.

The direct consequences of environmental pollution

Global warming and the greenhouse effect

The depletion of the ozone layer

Shrinking polar ice

The risen sea levels

Acid rain

Climate changes

Why is difficult to cope them?

The indrusty don't want to stop

The pollution has already exceeded a cretain limit.

Greenhouse effect.....

This efect is blamed for global warming and climate change

Carbon dioxide in the air is increased since the indrustial revolution

International steps have been taken to fight global warming

Forests

European and North American forests are threatened by forest death

  • due to pollution,
  • acid rain,
  • various diseases
  • climatic stress

Forests have these main functions...

  • they regulate the water cycle,
  • produce and protect soil,
  • provide habitat for animals and plants,
  • provide most of our oxigen,
  • the sources of half the medicine used wordlwide.

Deforestation causes the carbon in the trees to go into the air again

Animals

Future

Sustainable development

The concept of sustainable development basically pretains to city planning in such a way that is more energy efficient and less polluting for the enviroment.

The future of our planet

The technological developments will enable us to easily solve problems that may arise. With the help of advanced technology we will be capable of building energy saving homes.

Food problems can also be overcome by biotechnology or synthetic pills.

Enviromental pollution is steadily damaging our planet.

Day by day animal and plant species are dying out .

Much of Europe has been hit by a terrible heat wave.

Oil will run out in about 40 years.

Nature seems to be fighting a losing battle againts humanity
