Insect decline could have 'catastrophic' environmental impact

A recent study shows the number of insects around the world is declining rapidly, adding such a trend could have what it calls a "catastrophic" effect on the environment.
The study published in the journal Biological Conservation, claims more than 40 percent of insect species, including bees, ants and beetles could become extinct in the next few decades.
Researchers suggest such a decline could cause the collapse of the planet's ecosystems with a devastating impact on life on Earth.
The main reason for the drop is loss of habitat caused by agricultural practices, urbanization, as well as climate change.
