Genetic diversity Species diversity Ecosystem diversity

people like biodiversity human activities cause species extinction all living things including human being are involved in ecological interaction the evolution must go on each species has its own value as its own evolutionary history, unique ecological role and a fact of its existing

destruction of habitats and their fragmentation, over-exploitation of species introduction of exotic species increasing of disease spreading pollution climate changing

The environmental destruction is some kind of economical costs as well Ecological economy combines economy, environmental science, ecology and policy

to protect natural communities and populations to prevent negative consequences of introduction of alien species biodiversity must be integrated into the agriculture, fishery, and forestry sectors. To establish strong institutions at all levels limiting pollution assessing the full economic value of ecosystem services increasing the transparency of decision making processes

Biodiversity is the most important part of sustainable development. At present biodiversity is in crisis. The best way to conserve biodiversity permanently is to protect natural communities and populations. The Baltic Sea is a unique region which as other parts of the world has faced with problems of species extinction.
