Which of the following are true?

1. Habitat fragmentation is a threat to biodiversity which arises out of urbanisation.
2. Emerald Network was set up in Europe in 1998 to conserve the wild flora and fauna.
3. Developing habitat corridors for preservation of species might put biodiversity at risk due to interbreeding of species from different locations.

Urbanisation can split up habitat areas, causing animals to lose both their natural habitat and the ability to move between regions to use all of the resources they need to survive. Habitat fragmentation due to human development is an ever-increasing threat to biodiversity, and habitat corridors are a possible solution. The Emerald network is an ecological network to conserve wild flora and fauna and their natural habitats of Europe, which was launched in 1998 by the Council of Europe as a part of its work under the Convention on the Conservation of European Wildlife and Natural Habitats or Bern Convention that came into force on 1 June, 1982. Interbreeding is one of the aims of building habitat corridors, since it promotes genetic diversity and improves the overall population.
