Learn to Save Water
Water is very important for all living things. People, animals and plants all need water to live. But now, water pollution is becoming a serious problem in many cities.
Last spring, our school organized a popular educational activity. We visited a local water-saving base. At the base, we learned lots of professional knowledge. Workers introduced how wastewater is recycled and reused. They told us that over 70% of the earth is water, but only a small part is fresh water for people to drink.
In some dry areas, people walk far to get clean water. They can’t take a shower often and even save every drop of water for cooking and pared with them, we are much luckier, but we always waste water carelessly.
This special activity opened our eyes. It teaches us that water is precious. We must form good water-saving habits in our daily life. Small actions can make a big difference to protecting our natural resources.
