Sprint 2.5: Change In Amount

In our geography and science chapters, we often study how things change around us. For example, due to better healthcare and food availability, the human population has significantly over the last decade. On the other hand, during the harsh winters in the Himalayan region, the temperature often well below the freezing point. Changes also happen in materials around us; for instance, railway tracks can bend in summer because solid metals tend to when heated. To protect our environment from the negative effects of human activities, we must take immediate steps to pollution and greenhouse gas emissions. Understanding these natural and human-made changes helps us find better solutions for a sustainable future.
