The most basic answer is that the electromagnetic spectrum is the range of all the wavelengths (frequencies) of electromagnetic radiations. It basically describes the range of light in our universe.
Visible light is the only part of the EM spectrum we can see, but there are many kinds of invisible light waves. There are seven kinds of wavelengths in the EM spectrum: radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma. Radio waves have the lowest frequency, and therefore have the largest wavelengths, which means that gamma rays have the highest frequencies and smallest wavelengths in the electromagnetic spectrum.
1) One reason why deforestation is occuring because people need wood from trees to build things, therefore, leading them to cuting countless of trees.
2) One environmental problem that results from widespread deforestation is that the carbon dioxide they would normally use remains in the atmosphere, therefore, promoting erosion.
3) One way to lessen the effects of deforestation is by re-planting the cut-down trees and by cutting down less trees.
This was my answer from the same question that you asked before
