Mankind is busily manufacturing its way into extinction.

Any species that devours its natural environment will eventually fall victim to the resulting silence and I call the toxicity of silence: Extinction Silence

Ionizing smoke detectors unnaturally raise the background radiation levels in the human environment.

I have never heard of an electromagnetically hypersensitive person recovering from the condition using shielding and Faraday cages, they just seem to become social lepers due to their increasing reactivity to the city environment and addicts to their shielded environment.

I have every expectation that cancer will become known as the disease of human evolution trying and failing to adapt to a significantly changed environment.

Incorrect radiation levels may be able to affect your sex drive and it may be proven in the future that human sex drive is governed more by radiation types and levels than any other factor, even more so than hormones! Generally, a feeling of contentment replaces sexual desire in natural radiation environments.
