So many wild species struggle to survive in the face of human activity. Serious population declines over the last half century should instill fear in every human heart – we need these wild animals for our own survival.
- 76% population decline in freshwater species
- 70% decline in seabird populations
- 68% loss of common birds in the United States
- 40% of terrestrial populations lost worldwide
- 40% worldwide loss in marine species
Humans, by-and-large, disdain insect and arachnid species, either fearing them or labeling them as pests. Reasons are, for the most part, based in ignorance of the value these animals provide. We call these ecosystem services and natural capital, functions rooted in Nature upon which Homo sapiens depend for our own lives. Some of these, like the water cycle, are obvious to us – although we still foolishly complain when it rains. Also trees often get lots of credit for their oxygen production, however, when allowed to form a forest, trees up the ante on the services and capital we rely upon – erosion and flood control, water purification, lumber and paper products, etc., etc.
Insects, Spiders and other such animal species, however, do not get much credit for anything other than being “pesty”. When one considers the full web of life, it does not take long to realize that these invertebrates are critical to all life on Earth. I might even risk saying that they are second only to plants in importance, which explains why they vastly outnumber all other animal species.
This 1st and 2nd place rating is no coincidence. Without plants, no animal eats – none of them. All food is based in the plant world – and many, many plants greatly depend upon insects in order to reproduce, be it through direct pollination services or the protection certain invertebrate species provide to plants. Consider that approximately 75% of flowering plants rely on animal pollinators to reproduce. Of the over 200,000 species of animals who perform pollination services, 99.5% of them are insects, such as beetles, bees, ants, wasps, butterflies, and moths, or spiders.
Clearly we must educate ourselves on these essential animals. We need them or Homo sapiens becomes extinct. The factors that threaten invertebrates are far more than just fear and disdain. While we directly target some for annihilation with chemicals, others are being threatened by our use of resources – habitat loss, pollution (air/water/ chemical) and climate change being the top factors.
And our best-loved insects, the Butterflies, are not immune to humans’ insatiable use and misuse of natural resources. A recent study states that the Monarch Butterfly, an icon of Nature’s beauty, may be only 20 years from extinction. Why? Habitat loss in both its Winter and Summering grounds (they Summer and reproduce in Western New York), pesticides, genetically modified crops and climate change are the reasons.
And let’s think about those devastating population numbers above. What is the link to the invertebrate world? Many of these animal populations feed upon invertebrates, be it the adults, larvae and/or eggs. Mosquitoes are a favorite food of both birds and freshwater animals. Is it any wonder there is a rise in Mosquito-borne disease recently? The interconnectivity of Nature is still a mystery and we need to understand these complex relationships as they relate to our own behaviors and use of the natural world.
What can you do to help reverse such trends? Here’s some suggestions:
- Become knowledgeable about insects and spiders. Learn what services they perform that eventually trickle down to our own survival. And remember, the vast majority of these species pose no harm to you.
- Put the chemicals and fly-swatters away. First, it is a losing battle – their numbers are too great and many evolve quickly to survive chemical applications. Instead, make sure your screens are tight and intact, turn off lights near windows and doors, use natural repellents (like citronella, cloves and lemon balm).
- Create wildlife habitat, especially for those native pollinators in peril. All of Nature will benefit – see http://oakmossed.com/garden.php for lots of information on environmentally sound gardening, native plants and our invertebrate friends.
The future of Planet Earth is literally in our hands now. Our actions and failure to act will not only dictate the further existence of wild animals and plants, but our own existence, as well.
