Problems of ecology

We live in toxic times. Never before in recorded history have human beings been packed so closely together, under such toxic and stressful conditions, as in our cities today. Never before have we exposed our planet and our bodies to so many different kinds, and increasing quantities of toxins (poisons). This includes chemicals, heavy metals, toxic fumes, radiation, and other poisons in our air, food, and water. No one knows the full consequences of all these different toxins building up and interacting inside human bodies. But we can see some of the effects in bodies around us, or by looking in a mirror.

The problem of youth subculture as a social phenomenon is a relatively new topic for philosophical analysis, although its introduction to the social and philosophical questions prepared by many factors. First, the development of such sciences as sociology, cultural studies, history, psychology, education, ethics, showing interest in this subject. Second, a serious backlog, if not absence, understanding the phenomenon of youth subculture in our philosophy. Third, the assumptions by some researchers that the phenomenon of youth subculture is a temporary historical curiosity is not justified. Whether we like it or not, the phenomenon of youth subculture came into our lives and took its place in the social system.

We live on a very beautiful planet – on the Earth. Our planet has very rich resources: the bright blue of the sky, fresh, crystal-clear mountain lake water, the rich green of the mountains slopes, wild flower, picturesque views – all these sceneries of nature fill us with admiration.
That’s why those who live in cities prefer spending their days off and their holidays far from the noise of the city, to be closer to nature. Perhaps they like to breathe fresh air or to swim in clear water because the ecology is not so poor as in the cities.
Ecology is the study of the ways in which organisms (plants and animals) depend upon each other and upon their surroundings. Each organism requires conditions in order to be able to live and breed. These conditions are its environment by changing the ecological conditions

Until recently the planet was a large world in which human activities and the nature were in balance. Acid rain, global warming, ozone reduction, widespread desertification and species loss: we have to face them now.

Ecotourism is a form of tourism, which involves travelling to tranquil and unpolluted natural areas. According to the definition and principles of ecotourism established by The International Ecotourism Society (TIES) in 1990, ecotourism is “Responsible travel to natural areas that conserves the environment and improves the well-being of local people”.
There are a lot of definitions of ecotourism. They are green tourism, natural tourism, severe tourism. The last one means a type of a holiday in wild conditions without any conveniences.

Scientists now predict that by the year 2050 the population will be doubled what is today. The fact remains that the rate of food production fell behind population growth in many of developing countries. The annual fish catch already exceeds what the world ‘s oceans can successfully sustain. If we go on using our natural recourses at today’s rates, we will have used up the intire reserves of cooper, natural gas and oil by the year 2054. But the problem ahead lie not so much in what we use but in what we waste. What faces us is not so much a recourse crisis as a pollution crisis. The only solution is to try to change the areas of consumption, technology and population. Changes in technology must be baked by slower population growth. And it can be achieved by education in health and women’s rights. And there is a little hope of reducing consumption over the next half century.

Ecological problems
The Earth is the only planet in the solar system where there is life. If you look down at the Earth from a plane you will see how wonderful our planet is. You will see blue seas and oceans, rivers and lakes, high snow-capped mountains, green forests and fields. For centuries man lived in harmony with nature until industrialization brought human society into conflict with the natural environment. Today, the contradictions between man and nature have acquired a dramatic character. With the development of civilization man's interference in nature has increased. Every year the world's industry pollutes the atmosphere with millions of tons of dust and other harmful substances. The seas and rivers are poisoned with industrial waste, chemical and sewage discharge. People who live in big cities are badly affected by harmful discharge from plants and city transport and by the increasing noise level which is as bad for human health as lack of fresh air and clean water.
