Dear MEL Topic Readers,
New study suggests insect populations have declined by 75% over 3 decades
Only a quarter of insects are found to live in nature reserves in Germany now compared to 30 years ago, a new study says. Some may say that’s good news as they are less bothered by bees, ants, or cockroaches. But as insects make up about 70% of all animal species, they are crucial to biodiversity. They pollinate crops and plants, reduce pests, and control waste. It’s obvious that such drastic reduction in the population of insects could have significant impacts on the environment.
Why has their population decreased that much only in three decades? Various contributing factors are suggested for this decline, such as climate change, use of pesticides, and lost habitation.
How did they count the number of such small creatures for some period? They didn’t but measured.
Enjoy reading and learn how the scientists measured the number of insects, and think what sorts of impacts will the world see in the near future.
