Creating a seed bank in the arctic is a very important example of global cooperation. Many species of plants are fast ( ) appearing. As a result, a ( ) national effort is needed to save them. Although it might be expensive, the cost of such an effort is ( ) material compared to the lives it could save if there is a global food crisis. The seed bank could be run as a ( ) profit organization which would help to preserve the ( ) diversity of the planet. Furthermore, if the seed bank is in the arctic, there is no danger of the refrigeration systems ( ) functioning. This will also help with the ( ) preservation of shoots and seedlings. While the global seed bank would not ( ) place seed banks in individual countries, a ( ) governmental effort would create an important backup to the local seed banks. Finally, a successful example of global cooperation like a seed bank would improve ( ) politics for years to come.
