“You are going to enter the largest wild seed bank in the world,” said Sharon Balding. She is the Seed Collections manager at the Millennium Seed Bank (MSB). This seed bank is in Sussex, UK. “Inside there are over 39,000 different kinds of seeds from more than 100 countries. That’s over 2.8 billion seeds,” Sharon said. She turned a key, and the heavy door slowly opened.
Inside the MSB, there are many glass bottles with seeds. The bottles are named with numbers, not plant names. “This is for safety,” Sharon said. “If someone takes the seeds away, he won’t know what they are!” So, is the collection worth a lot of money? “It’s invaluable,” said Sharon. “Our future life rests on these seeds. Without them, we could lose important things, like food and medicines.”
Some seeds here have already helped. For example, in early 2020, fires in Australia burned down the natural environment of a special plant. The MSB sent 250 seeds back to the country to help the plant reestablish itself in the wild again.
As the world gets warmer because of climate change, it will be harder for some plants to live in the UK. “One day it may be too warm for some of the UK’s trees to grow,” said Owen Blake. He is part of the UK Tree Seed Collecting Team. “So we are looking for and studying trees from other parts of the world. Some of these trees can grow in the warmer UK climate,” he said.
