Covid 19; Disease Spread and care for the Earth

It is yet another Earth day commemoration. But this time for a lot of communities around the world, the events are being marked sombrely.  Nearly all of earth's human citizens, over 7 billion of us are hunkered in waiting for the worst of this deadly invisible virus to pass.
Lives have been lost, the global economy decimated as the disease now officially a pandemic continues to take no prisoners. At a time such as this, once the crisis is over we need to put aside our old ways of doing things. It has brought us immense benefits but also great harm.

None is advocating communism but certainly, unregulated capitalism is equally as bad.
Some studieshave shown that deforestation pushes the spread of vectors. While epidemiologists are still working their way to understanding the novel virus; perennial hos…

5G is not the Enemy

Around and present, surrounding us, every time and all times are rays bound together in electric and magnetic fields called electromagnetic radiation. They travel at the speed of light. Nothing goes faster than their energies in a vacuum. It is as normal as the rain, our oceans, the sky, rainbows, animals, etc except, unlike these other objects we can’t see the full length and breadth of the electromagnetic spectrum. The part of it we can see called light makes a tiny part of the whole. The seven parts of the spectrum in ascending frequency are Radio wave, Microwave, Infra-red, Light, Ultraviolet, X-ray, and Gamma-ray.
The theoretical equations linking electricity and magnetism had been made in 1873 by James Clerk Maxwell. So, when Henrich Hertz first discovered radio waves in 1886, giving proof to Maxwell’s equation he thought no more of it. It was G. Marconi who in 1896, would get a patent for its use and deploy it towards wireless communication.  It transformed the world. 
Thence, rad…
