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. <br />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.<br />Researchers suggest such a decline could cause the collapse of the planet's ecosystems with a devastating impact on life on Earth.<br />The main reason for the drop is loss of habitat caused by agricultural practices, urbanization, as well as climate change. <br />
