"Safe water is not necessarily pure; it may contain some impurities such as traces of salts like magnesium, calcium, carbonates, bicarbonates, and other minerals. The degree of purity and safety of water is relative and can be a topic of debate. On the other hand, pure water or distilled water has no minerals and only contains hydrogen and oxygen."

"Trees play a crucial role in reducing the greenhouse effect by removing carbon dioxide from the air and releasing oxygen. A mature tree can produce enough oxygen for ten people in a year. Trees are also effective in reducing noise pollution and act as a sound barrier. Recent studies have shown that trees help reduce stress caused by modern life."

It is essential to have proper waste segregation systems in place. The segregation of hazardous and non-hazardous waste can be achieved by installing separate bins or supervising waste disposal sites. This practice can improve the rate of recycling, reduce costs, and minimize the overall impact of waste on the environment.
