Живые организмы, живущие на Земле,

Живые организмы, живущие на Земле, представлены огромным разнообразием. Это разнообразие формировалось в течение более 4 млрд. лет. Сейчас оно сокращается ускоренными темпами. Влияние человеческого общества на биосферу постоянно нарастает. (Существование же людей на планете напрямую зависит от обеспеченности их различными продовольственными ресурсами, что в свою очередь связано с видовым разнообразием в биосфере.)
Основными причинами сокращения биологического разнообразия являются:
- разрушение естественных экосистем в результате вырубки лесов, расширения пахотных и пастбищных площадей, строительства городов, прокладки дорог, каналов, других коммуникаций;
- рост населения планеты и развитие его хозяйственной деятельности; загрязнение атмосферы производственными выбросами;
- применение ядохимикатов в сельском хозяйстве, вызывающее гибель насекомых, птиц, рыб, некоторых видов животных.
Сейчас темпы исчезновения отдельных видов в 50— 100 раз превышают естественный показатель. Примерно четверти всех видов животных и растений планеты угрожает исчезновение в ближайшие 20—30 лет. В книгу внесены 14 млн. видов животных и растений,

Ежегодно гибнет более 11 млн. га леса. Значительная часть территории, на которой ранее росли леса, превращается в сельскохозяйственные земли низкого качества, которые не могут прокормить живущих на этих землях людей.
Для сохранения (биологического) разнообразия необходимо обеспечить:
- сохранение лесов;
- охрану водной и воздушной среды;
- защиту нетронутого еще человеком биологического богатства.
Для сохранения флоры и фауны создаются заповедники.

К таким центрам относятся озеро Байкал и Прибайкалье, юг Дальнего Востока, кавказский регион.
В рамках Программы защиты окружающей среды при ООН разработана Концепция о биоразнообразии. Цель данной концепции — информировать и убедить мировую общественность в том, что уничтожение биоресурсов угрожает самому существованию человека на Земле.

Organisms living on Earth, presents a huge variety. This diversity was formed for more than 4 billion. years. Now it is declining at an accelerated pace. The impact of human society on the biosphere is constantly growing. (The existence of people on the planet depends on the availability of different food resources, which in turn is associated with species diversity in the biosphere.) The main causes of loss of biological diversity are: -destruction of natural ecosystems as a result of deforestation, the expansion of arable and grazing areas, construction of cities, roads, canals, and other communications; -world population growth and the development of its business activities; industrial pollution emissions; -the use of pesticides in agriculture, causing the deaths of insects, birds, fish, some species of animals. Now the rate of extinction of species in 50-100 times the natural rate. About a quarter of all animal and plant species on the planet is threatened by extinction in the next 20-30 years. In the book made 14 million. species of plants and animals, More than 11 million are killed annually. HA of forest. A large part of territory in which the earlier forest grew, turning into agricultural land of low quality, which cannot feed the people living on these lands people. For the preservation of biological diversity must ensure: -forest conservation; -protection of water and air Wednesday; -protection of pristine still man of biological wealth. To preserve the flora and fauna creates reserves. Such centres include Lake Baikal and Baikal, South of the far East, Caucasus region. Within the framework of the programme for the protection of the environment Wednesday to the UN developed the concept of biodiversity. The aim of this concept is to inform and to convince world public opinion that the destruction of bio-resources is threatening the very existence of man on Earth.

Living organisms living on Earth, presented a huge variety. This diversity was formed for more than 4 billion. Years. It is now declining rapidly. The impact of human society on the biosphere is constantly growing. (The existence of people on the planet depends on the availability of different food resources, which in turn is connected with the diversity of species in the biosphere.)
The main causes of biodiversity loss are:
- the destruction of natural ecosystems as a result of deforestation, the expansion of arable and pasture areas, construction cities, roads, and canals, and other communications;
- The growth of world population and the development of its business activities; industrial air pollution emissions;
- The use of pesticides in agriculture, causing the death of insects, birds, fish, some species of animals.
Now the rate of extinction of certain species in 50 100 times higher than the natural rate. About a quarter of all species of animals and plants threatened with extinction of the planet in the next 20-30 years. The book included 14 million. Animal and plant species,

die every year more than 11 million. Hectares of forest. A large part of the territory where previously grown forests converted to agricultural land of low quality, which can not feed the people living in these lands people.
Necessary to provide for conservation (biological) diversity:
- preservation of forests;
- The protection of water and air pollution;
- The protection of untouched even human biological wealth.
To preserve the flora and fauna are reserves.

These centers include the Lake Baikal and the Baikal region, south of the Far East, the Caucasus region.
As part of the environmental protection program developed by the UN concept of biodiversity. The aim of this concept - to inform and convince the world community that the destruction of biological resources threatens the very existence of man on earth.

living organisms living on earth, brought the huge variety. this diversity has for more than 4 billion. years. now it is declining rapidly. the impact of human society on the biosphere is steadily increasing. (the existence of human beings on the planet is directly dependent on the availability of different food resources, which in turn is linked to the species diversity in the biosphere.the main causes of biodiversity loss are:the destruction of natural ecosystems as a result of deforestation, expansion of arable and grazing land, the construction of cities, roads, canals, and other communications;growth of population and the development of its economic activities; the pollution of atmosphere in the production of emissions;application of pesticides in agriculture, causing the death of insects, birds, fish, and some species of animals.now the rate of disappearance of individual species is 50 to 100 times the natural rate. approximately a quarter of all species of animals and plants in the world in the next 20 to 30 years. in the book made $14 million. species of animals and plantsdie a year more than 11 million. hectares of forest. a large part of the territory in which the previously grown forests into agricultural land of inferior quality, which cannot feed the people living in these areas.for the conservation of biological diversity should ensure that:- the preservation of forests;- water and atmosphere protection.- protection of pure a man of wealth.for the conservation of flora and fauna are protected areas.such centres include lake baikal and прибайкалье, south of the far east, the caucasus region.the programme for the protection of the environment in the un developed the concept of biodiversity. the purpose of this concept is to inform and convince the world public that the destruction of biodiversity threatens the very existence of man on earth.
