In 2016, a group of researchers from across the globe came together to conduct the largest study on insect populations ever done. The aim? To determine whether insect numbers are declining and at what rate. The idea was inspired by something relatively simple – an almost spotless windscreen. Having trekked through the backroads of Denmark for a month, about 200 Danish researchers noticed the lack of bugs splattered across their car windows, leading them to ask the question: where have all the insects gone?
Now, just over two years later, a first-of-its kind study reveals our insects are in serious trouble. Having looked at 73 historical studies on insect numbers, scientists were able to determine that there is indeed a dramatic rate of decline among insect species, with more than 40% of the world’s insect species facing possible extinction. And with insects making up the very foundation of all ecosystems, their disappearance could have terrible consequences for all other life forms.
YOU CAN MAKE A DIFFERENCE
Fortunately, humanity still has a fair number of years to try and slow down the so-called insect apocalypse. From making simple changes in your own backyard to educating others – we can all make a difference.
- Try and plant indigenous plants that attract insects and pollinators. This not only helps keep invasive species at bay, but also ensures a healthy, ever-growing local bug population in your garden.
- Avoid planting hybrid plants that form double blooms – flowers with several petal layers. Although these flowers look pretty, they make it a lot of harder for pollinators to gain access to the nectar.
- Don’t use bug zappers as they are indiscriminate and kill off many beneficial insects including moths and butterflies which are at most risk of extinction.
- Don’t use pesticides unless absolutely necessary. Rather do an online search for eco-friendly pest control solutions before reaching for that can of insecticide.
- Try and use organic fertilisers when possible as they tend to attract more insects.
- Don’t rake up all the leaves in your garden beds. A thin layer of leaves often serves as a natural ground cover and provides shelter for many insects.
- Be more conscious of your carbon footprint and try and make eco-friendly changes where you can. Try and source locally-produced products and, if possible, grow your own.
