UPDATE: Due to high demand, Cheerios is all out of wildflower seeds. According to the website, they gave away around 1.5 billion seeds.

Cheerios is sending 100 free wildflower seeds to anyone who signs up on their website to help save the bees.

According to their website, Cheerios pledged to send out 100 million wildflower seeds in partnership with Veseys Seeds as part of their #BringBacktheBees campaign.

"People need bees. And now bees need people," the website says.

The campaign asks that once you receive your wildflower seeds, you plant them in a "bee-friendly" area.

In addition, Cheerios has removed "BuzzBee," its classic spokesbee, from boxes in the United States and Canada, to raise awareness about declining populations of pollinators.

“As a General Mills cereal built around nutrition, helping pollinators get the key nutrition they need through fun, family-friendly activities like planting wildflowers is a natural fit,” said Susanne Prucha, director of marketing for Cheerios.

In a release about the campaign, Cheerios' parent company General Mills pointed to the critical need for bees to pollinate more than two-thirds of the crops used to feed people. Approximately 30 percent of all ingredients in General Mills’ products also rely on pollination, according to the release.
