Every year, human activities cause climate change due to a large amount of carbon dioxide released into the atmosphere. Global warming and an unbalanced ecosystem have increased the number of natural disasters around the world. However, the number of human lives lost during these disasters is declining. The main factor is technology. These days, natural disaster forecasters use advanced technology to predict future weather events. In the past, storm predictions only came 24 hours in advance. Now, people usually have three days to prepare before the storm hits. Many experts agreed that time could save many lives during natural disasters. With the increasing use of smartphones, natural disaster warning systems have also come a long way. Applications are available to send messages to people in affected areas as soon as there is news about an upcoming disaster.
