Irrigation causes an increase in salt which will kill plants. Pesticides poison water making it undrinkable. Pesticides can contaminate the soil for long periods of time.
Cell phones emit radiofrequency radiation (radio waves), a form of non-ionizing radiation, from their antennas. Parts of the body nearest to the antenna can absorb this energy. ... Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased.
Explanation:
Ciclo del Carbono
Un 18% de la materia orgánica viva está constituida por carbono, la capacidad de dichos átomos de unirse unos con otros proporciona la base de la diversidad molecular así como el tamaño molecular. Por tanto el carbono es un elemento esencial en todos los seres vivientes.
A parte de la materia orgánica, el carbono se combina con el oxígeno para formar monóxido de carbono (CO), dióxido de carbono (CO2), también forma sales como el carbonato de sodio (Na2CO3), carbonato cálcico (en rocas carbonatadas, como calizas y estructuras de corales).
18% of living organic matter is made up of carbon, the ability of these atoms to bond with each other provides the basis for molecular diversity as well as molecular size. Therefore carbon is an essential element in all living beings.
Apart from organic matter, carbon combines with oxygen to form carbon monoxide (CO), carbon dioxide (CO2), it also forms salts such as sodium carbonate (Na2CO3), calcium carbonate (in carbonate rocks, such as limestone and coral structures).
