The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise and update several species lists.

Areas of Biodiversity Importance

In addition, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change. The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach to preserving biodiversity. Almost all cultures have their roots in our biological diversity in some way or form. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. And so, while we dominate this planet, we still need to preserve the diversity in wildlife.

The Areas guide provides short articles about selected areas of importance for biodiversity conservation. It explains in detail a number of recognised systems to protect, prioritise and identify areas of biodiversity importance that fall into two main categories: protected areas and biodiversity designations. Area designations categorised as protected areas are those under protected area frameworks, that have legal or other effective protection at the national level. Some have additional recognition through regional or international conventions and agreements. Area designations categorised as biodiversity designations are developed by governments, academics and NGOs in order to identify areas of biodiversity importance or areas where biodiversity is threatened, as a means to focus attention and resources on their conservation.

Freshwater biodiversity: importance, threats, status and conservation challenges

The core threat to biodiversity on the planet, and therefore a threat to human welfare, is the combination of human population growth and resource exploitation. The human population requires resources to survive and grow, and those resources are being removed unsustainably from the environment. The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species. The first two of these are a direct result of human population growth and resource use. The third results from increased mobility and trade.

Biodiversity or Biological diversity is a term that describes the variety of living beings on earth. In short, it is described as a degree of variation of life. Biodiversity also refers to the number or abundance of different species living within a particular region. It represents the wealth of biological resources available to us. If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us. In biodiversity, each species, no matter how big or small, has an important role to play in the ecosystem. Various plant and animal species depend on each other for what each offer, and these diverse species ensure natural sustainability for all life forms.

Biodiversity is the biological variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level. Rapid environmental changes typically cause mass extinctions. The age of the Earth is about 4.

Threats to Biodiversity

 - Через пятнадцать минут все страны третьего мира на нашей планете будут знать, как построить межконтинентальную баллистическую ракету. Если кто-то в этой комнате считает, что ключ к шифру-убийце содержится еще где-то, помимо этого кольца, я готов его выслушать.  - Директор выдержал паузу. Никто не проронил ни слова. Он снова посмотрел на Джаббу и закрыл .

Беккер открыл конверт и увидел толстую пачку красноватых банкнот. - Что. - Местная валюта, - безучастно сказал пилот. - Я понимаю.  - Беккер запнулся.  - Но тут… тут слишком. Мне нужны только деньги на такси.

Сознание гнало ее вперед, но ноги не слушались. Коммандер. Мгновение спустя она, спотыкаясь, карабкалась вверх по ступенькам, совершенно забыв о таящейся внизу опасности. Она двигалась вслепую, скользя на гладких ступеньках, и скопившаяся влага капала на нее дождем. Ей казалось, что пар буквально выталкивает ее наверх, через аварийный люк.

Habitat Loss

 Какому соглашению? - Немец слышал рассказы о коррупции в испанской полиции. - У вас есть кое-что, что мне очень нужно, - сказал Беккер. - Да-да, конечно, - быстро проговорил немец, натужно улыбаясь. Он подошел к туалетному столику, где лежал бумажник.

What is Biodiversity?

Как правильно ответить. - Viste el anillo? - настаивал обладатель жуткого голоса. Двухцветный утвердительно кивнул, убежденный, что честность - лучшая политика.
