Some hundreds of years ago people lived in harmony with nature, because industry was not much developed. Today, however, the contradictions between man and nature are dramatic.
The twenty first century is a century of the scientific and technological progress. The achievements of the mankind in mechanization and automation of industrial processes, in chemical industry and conquering outer space, in the creation of atomic power stations and ships are amazing. But at the same time, this progress gave birth to a very serious problem – the problem of environment.
Ecology and the contamination of environment, is concerned with climate, over-population in certain areas, deaths of plant and animals, chemical contamination of seas, lakes and rivers as well as atomic experiments and dumping of atomic waste from power stations. Floods, unexpected draughts, and the greenhouse effect are the next reasons.
There are many consequences of damaging the environment. One of them is acid rain. Another one is water shortage resulting from abuse of arable lands in agriculture. The third one is destroying the ozone layer of the Earth through pollution from factories and plants. The fourth problem is damage o water and soils.
The fifth one is damage to wildlife: numerous species of animals and plants can disappear. At last, the most serious danger arising from damaging the environment is the result of the abovementioned consequences. This is the danger for the life and health of the man.
The protection of natural resources and wildlife is becoming a political programme in every country. Numerous anti-pollution acts passed in different countries led to considerable improvements in environment. In many countries purifying systems for treatment of industrial waters have been installed, measures have been taken to protect rivers and seas from oil waters.
But the environmental problems have grown beyond the concern of a single country. Their solution requires the co-operation of all nations. If we are unable to learn to use the environment carefully and protect it from damage caused by man’s activities, very soon we’ll have no world to live in.
Environmental protection is a practice of protecting the environment, on individual, organizational or governmental level, for the benefit of the natural environment and (or) humans. Due to the pressures of population and our technology the biophysical environment is being degraded, sometimes permanently.
This has been recognized and governments began placing restraints on activities that caused environmental degradation. Since the 1960s activism by the environmental movement has created awareness of the various environmental issues. There is not a full agreement on the extent of the environmental impact of human activity and protection measures are occasionally criticized.
Academic institutions now offer courses such as environmental studies, environmental management and environmental engineering that study the history and methods of environmental protection. Protection of the environment is needed from various human activities. Waste, pollution, loss of biodiversity, and the introduction of invasive species are some of the issues relating to environmental protection.
Some people believe that having a hero is useful. Others stat that it is childish.
Children are genius creations in my opinion. I am one of those weird people who admires them more than adults. I like the way they are able to think freely, to express themselves in the way they want and to follow examples they think are better for them. Every child has a hero, an example he admires and follows in everything he does. Usually it is his mother or father, with rare exceptions including thei grandparents, friends or random acquintances. Nevertheless, boys use to set as their hero a mystical character they've encountered in books or seen on TV, like Superman, Batman, Spiderman and so on. These fictional heros are good as well in my opinion, as children will learn to be brave and help others. It is a much bigger problem if they find a hero in a negative character as it will develop some negative parts of a children's behaviour. Having a hero will motivate a child to become someone and acquire the features that will soon form his behaviour. From this point of view, I think that adults should set an example for themselves as well. I believe this will encourage them to do things better, to compete in order to achieve their goals and to change their nature in a better way. So, I don't think that having a hero is childish and we totally shouldn't avoid it, thinking that we are too mature for this. That being said I think we as adults have a lot to learn from children. Not only that they are free to do whatever they want, they are also following great examples that will help them become one day an example as well.
