Where Have the Insects Gone

Where have all of the insects gone?  In years past I would walk around a section of our wetlands and make lots of pictures of insects.  I repeated that trip Saturday morning and found very few insects.  I think the insects and the songbirds and the butterflies are getting fewer and fewer due to loss of habitat, poisoning, and climate changes; i.e., we are killing them off.  Another way of looking at it, we are killing ourselves off slowly but surely if we don’t change course soon.
