The Economy depends on the Nature

Human life is intrinsically linked to biodiversity. If we can change our relationship with nature, we can not change our dependence. We use the forest services and depend on them.

According to a UNEP study, 40% of the world economy is based on ecological products and processes. An American economist Guind Institute for Ecological Economics (Constanza), believed in 1997 that the value of ecosystems is 33 000 billion (against 18 000 billion to global GDP)!

More broadly, ecosystems provide four types of services that we use directly:

  • Provisioning services are the products obtained from forests such as: food, fiber, medicines, drinking water, energy …

Forests are the basis of more than 5000 commercial products. 25-50% of the $ 640 billion pharmaceutical market originate in natural compounds

  • Regulating services are the benefits obtained from ecosystem processes: climate regulation, protection against floods and storms, crop pollination, resistance to invasions, water purification and air …

One third of the world’s food needs pollinating insects.

  • Cultural services are the non-material benefits such as personal enrichment, scientific discovery, aesthetic development, entertainment, education, inspiration …
  • Support services to maintain the conditions for life on Earth: soil formation, oxygen production … They are necessary for the implementation of all other services.

All the interest of protecting the ecosystem lies in the fact of not having to pay tomorrow for services that are now provided for free.

The cost of inaction and service degradation account for up to 7% of global GDP per year in 2050 according to the studies of the European Union (TEEB Pavan Sukhdev 2008).
