POLLUTION
Modern-day man enjoys many different kinds of comforts, such as machines and faster and more efficient means of transport. In certain aspects, we can say that he has managed to dominate nature. Waste products. Radioactive left-overs, Dwindling natural resources. Biological cycles. Mankind has altered nature’s delicate balance. Industry – our greatest producer of residues. Acid rain. Recycling techniques. Cities. Biodegradable products. The countryside. Summary.

INTRODUCTION
- We are filling the ground, atmosphere and water with unnatural products. Some of these products can be dangerous and even lethal.
- Danger of the radioactive waste. Nuclear power plants.
- Destruction of our environment. Smoke from factories and many transport systems which dump their waste into seas and rivers.
- The health of mankind and also the life of animals and plants are jeopardised.
- Depletion of the available quantities of natural resources.
BIOLOGICAL CYCLES
- All living-beings produce waste products which may damage other living-beings or the environment itself.
- There are animals which live exclusively on manure of other animals.
- Other animals eat dead animals, thereby eliminating possible residues of organic material which could otherwise be the cause of possible illnesses.
- Man has altered this natural, biological balance. Human civilisation produces so much waste nowadays, that nature simply cannot absorb all of it
- Consequences
INDUSTRY
- Waste products generated by industry and power-plants.
- There are many substances which suffer chemical changes when they are freed into the atmosphere.
- The sulphur-dioxide.
- The acid rain
- The use of the rivers: industry refrigeration and cleaning
- Re-cycling sewage waters
CITIES
- Pollution in the atmosphere
- Solid waste in the shape of rubbish
- Recycling
THE COUNTRYSIDE
- Nature suffers the effects of human pollution in a very direct way
- Forests and the acid rain
- Forest fires and indiscriminate felling
- Insecticides, DDT and the food chain
