Explanation:
After a muscle fiber is stimulated by a nerve signal, a release of stored calcium ions leads to muscle contraction.
Common electrolytes include sodium, chloride, magnesium, calcium and potassium.
Sodium and potassium help in the generation of nerve impulses while calcium aids muscle contraction. Sodium is also actively involved in the movement across cell membranes.

According to wikipedia, <em>"Waste are unwanted or unusable materials. Waste is any substance which is discarded after primary use, or is worthless, defective and of no use. Examples include municipal solid waste, hazardous waste, wastewater, radioactive waste, and others." </em>Assuming what you are asking is how can our garbage affect our environment, you're answer is not one singular sentence.
The answer would be something along the lines of this: The waste produced by what we consume and throw away can harm people and animals alike due to factors like plastic not being biodegradable, plastic that then pollutes our water, land, and even our air if burnt. Animals can easily consume waste and become ill or be trapped in it and become injured. Overall, our waste management and consumptions of plastic need to change to prevent harm to us by the poisoning, damaging, and crowding that we currently inflict on ourselves and other creatures. Adding to this, our management of biological and hazardous waste is well under control. If there were a breach in this there would be no clean water nearby, no safe meat to eat if animals consume the waste or contaminated water/plants. And the crops would likely die.
