All living organisms need rest/sleep so that their bodies can function properly, but it is flabbergasting to hear that great frigate birds can travel for long distances without sleep. As mentioned in this article, these birds might be facing difficulties due to the harsh winds and other climatic conditions, which will make it difficult for them to find food and prevent them from flying. Of course, this is not to ignore the fact that the cause for these conditions are our careless actions. Not only is this affecting birds, but several other animals are suffering. But, remember that however much action is taken to save these animals from being endangered, they will diminish from our planet. That is an eternal truth, because one day, even the most intellectual beings inhabiting the Earth will disappear.
