May is here and, if you haven't done so already, you'll almost certainly be thinking that it's time to mow the lawn. But Sir David Attenborough is asking you not to.
What's know as No Mow May asks people to delay cutting their grass to help wildlife flourish. The idea is backed by Sir David who, in his latest BBC series, made the plea to "delay mowing", reports YorkshireLive.
This is because insects and wildflowers use lawns to breed, pollinate and otherwise maintain a healthy ecosystem at this time of year, and shredding the grass down interferes with all that, killing off lots of insects that are an essential - and increasingly threatened - part of our ecosystem. If those insects die off, we all die off eventually.
