A seed bank, also known as a "plant gene bank", is a place where plant germplasm resources are stored and protected. Their purpose is to ensure the genetic diversity of plants so that these species can be reintroduced if needed in the future. Here are some reasons why we need to set up a seed bank:
First, seed banks are an important means of conserving plant diversity. Plants are an indispensable part of the earth's ecosystem, providing humans with food, medicinal herbs, timber and other resources, while also helping to maintain ecological balance. However, many plant species are in danger of extinction due to human activities and natural disasters, among other reasons. Seed banks can store the seeds of these endangered species and provide them with safe protection to ensure that their genetic information is not lost.
Second, seed banks can provide a valuable resource for agriculture and horticulture. With climate change and environmental degradation, some traditional crops and horticultural plants may lose their adaptability. Seed banks can provide genetic material for these species to help breeders breed new varieties that adapt to new environments. In addition, seed banks can provide plant pathologists with research materials to help them understand and study issues such as plant diseases and pests.
Third, seed banks also help to protect cultural and ecotourism resources. The plant species of many regions are an important part of the region's culture and ecotourism. If these species become extinct, not only will ecotourism resources be lost, but also the livelihoods and cultural heritage of local residents will be affected. Seed banks can provide opportunities for local communities to reintroduce these species, thereby preserving cultural and ecotourism resources.
Finally, seed banks also help protect biosecurity. Some plants may carry pathogens or toxins that are harmful to humans and animals, and these species can pose a threat to human and animal health if they get out of control. Seed banks can help monitor and control the spread and impacts of these species.
In summary, the establishment of seed banks is of great significance for the conservation of plant diversity, the promotion of agriculture and horticulture, the maintenance of cultural and ecotourism resources, and the protection of biosecurity. Therefore, we should actively support and participate in the establishment and operation of seed banks to ensure that our future generations can have a healthier and more sustainable ecological environment.
