Natural selection is a universal law. We must adapt to the environment, or risk falling behind in the race. Since the beginning of life on Earth, human evolution has occurred and will continue to occur, as Charles Darwin noted, everything is based on those two principles: survival and natural selection. It happens in various ways, sometimes through pandemics, extreme temperatures, or extreme cold, floods, earthquakes. In current times, we are experiencing extreme temperature conditions in nature. During the daytime, it's really difficult to stay outside. Meteorological authorities have issued red alert heat warnings to the country. According to them, this is due to heat waves from the sun. According to the image below, all Asian countries and one-third of the world are experiencing this extreme weather condition. During the day, outside temperature is around 45-50 degrees Celsius. People over the age of 60 and children under the age of 3 are in the danger category. This is the first time I am experiencing this type of extreme hot weather. ![image.png](https://cdn.steemitimages.com/DQmYAx2DRr7nb6UQ6bPNazTDt9ffARK1qUgrFjvNBumr6Na/image.png) _Facebook Global temperatures are also rising, glaciers are melting, and sea levels are increasing. Small islands like the Maldives are on the brink of sacrificing their lands to the sea. It's time for the people of planet Earth to take this matter seriously; otherwise, human species may become extinct from the planet Earth before long. It's very challenging to spend these days. We have to drink water frequently, and extreme sweating leads to a decrease in sodium ion levels in the body, causing muscle cramps. Therefore, it's better to consume extra salt during these days. It's advisable not to stay outside for long periods during the daytime and to postpone outdoor activities. We also need to take care of children and elderly Persons. Thank You! Dilshan
