"I Wish You Bluebirds in the Spring"
I do know that many birds suffered, including the eagles, from weakened egg shells (Lundholm, 1997) and it became a national uprising to ban this egregious, hormone disrupting chemical from use in the United States (Environmental Protection Agency, 2022). It is unfortunate that many countries still use DDT (National Pesticide Information Center, 1999) and it is a solid conjecture with high likelihood that DDT may continue to ride in, impregnated in the multitude of foods we import (Center for Disease Control, 2022). The world still has a lot of catching up to do but given the efforts of certain chemical manufacturers, the ecological alarms are being muffled continually by the implementation of even more dangerous products such as glyphosate (Center for Disease Control, 2020). Not only has glyphosate been shown to be a hormone disruptor, but a recent study has shown that it does cross the blood-brain barrier and is possibly implicated in Alzheimer's disease (Winstone et al., 2022). Most if not all of you did not have to swim in DDT like I did, but you are literally swimming in a sea of herbicides like glyphosate that may cause damage yet unknown (Marino et al., 2021). Is it possible that the recent falling sperm and fertility rates across the world are due to chemicals like these (Anifandis et al., 2018; Sengupta et al., 2017; Serra et al, 2021). It is imperative that we insist that corporations, especially those with conflicts of interest like the herbicide/GMO producers, be held accountable for their ethical behavior in regard to current and future harm to our ecosystems and all life on this earth.
I do hope that the world will recognize our ecological needs soon, for all of our sakes. I would like to wish you all a safe and happy future, and to quote the late great Natalie Cole (2022), forever and ever continued, "I Wish You Bluebirds in the Spring" (NatalieColeMusic. 2022).
