A healthy natural environment is important for social wellbeing and for the economy. That is why the government wants to preserve and strengthen the natural environment of the Netherlands. Biodiversity is in decline all over the world. The number of species of animals, plants and microorganisms is decreasing. The government is therefore keen to preserve and sustainably exploit biodiversity at both national and international level. The aim is to enhance the biodiversity of natural systems by 2020, so that these systems will contribute to water and food security, poverty reduction and wellbeing.
