There is no doubt that the actions such as using too much water or throwing rubbish into the rivers can put our water supply in danger. However, we could also affect the water supply in less obvious ways, for example, paving(铺砌))a road. Some may feel confused and wonder how such actions could result in less usable fresh water. To understand it, we have to know that a main component of our daily-used water is groundwater. Despite its name, it does not come from lakes or rivers on the ground。Instead, it comes from underground. The more roads and parking lots we build, the less water there is that flows into the ground to become groundwater.
However, human activity is not responsible for all water shortages. Places with drier climates are of course more likely to have droughts than areas with more rainfall.Regardless of the cases, good management can help ensure enough water to meet our basic needs.
Meanwhile, paying more attention to the way we use water can make a difference, too. According to recent research, each American uses more than 80 gallons of water a day at home on average! This shows how much we depend on water to live, but there is a lot we can do to lower the amount.
We can take steps to save water at home. To start with, use the same glass to drink water all day and wash it only once a day. Also, run the dishwasher only when it is full and use it in water-saving mode. Meanwhile, fix any leak in the house to avoid wasting water. We can also help to keep our water supply clean by recycling batteries and other rubbish instead of throwing them away.
