Growth is a biological process that refers to the fact or action of growing or expanding, as well as to the notion of increase, development and propagation.
In economics, growth refers to an increase in the production of goods and services.
Due to the booming worldwide movement of people and goods, as well as the development of new trade routes and improved means of transport, the number of animal and plant species introduced into new regions is constantly rising.
At the same time, global warming undermines local ecosystems and favours the development of certain exotic species, which then become invasive.
Invasive Alien Species (IAS) are one of the main causes of biodiversity loss and the second most frequent cause of species extinction, disrupting ecosystems.
This phenomenon represents a major ecological, economic and public health challenge.
IAS know no borders.
As in the case of global warming, IAS mainly affect the most vulnerable populations.
They primarily settle in disturbed and depleted ecosystems.
As sea levels rise and land areas shrink, competition for resources increases.
IAS are generally highly adaptable and reproductive, enabling them to colonize new territories to the detriment of local species. They often benefit from a competitive advantage as they escape their natural predators and parasites present in their region of origin.
Plants will therefore react differently to climate change, particularly in response to rising CO2 concentrations in the atmosphere. This could accelerate their growth...
It's a long-term problem, for which we are contracting an ecological debt.
