Scientists say that many of the world's plants in danger of dying out – of becoming extinct. Dr Paul Smith, from Botanic Gardens Conservation International, said one in five of the world's plants in danger of extinction. The world's botanic gardens about 100,000 species, including a third of all the world's endangered plants. Botanic gardens to around 40 per cent of endangered species of plants. They contain many of the rarest plants. Dr Smith said: "This is the first time that we have out a global assessment to at the wide range of plants , managed and conserved in botanic gardens. For the first time we what we have and, perhaps more importantly, what missing from botanic gardens."
Researcher Dr Samuel Brockington the world's botanic gardens were the best hope for saving the world's most endangered plants. He said: "Currently, an estimated one-fifth of plant diversity under threat, yet there no technical reason why any plant species should extinct." Dr Brockington that if we do not protect endangered plants, people could trouble finding food and fuel in the future. He said: "If we do not our plant diversity, humanity will to solve the global challenges of food and fuel security…and climate change." Most of the plants in danger because of humans down forests for farming and cities, and because of pests and climate change.
