The statement that “The number of creatures living on Earth has increased over time”is false. Over the time scientist has proved that it is a fact that organisms and animals have been decreasing over the years and different time periods. At Least more than 75% of species disappeared. But,it varies in the reasons why they are decreasing.
One of the main reasons they are decreasing is due to the climate change and global warming.Global warming around the world has caused a great confusion and disruption .For example, Iceland ”The Arctic sea ice has shrunk to new lows in recent years, due in part to human-caused global warming. This has had a direct effect on animals that live on the ice, such as polar bears. As the Earth gets warmer, plants and animals that need to live in cold places, like on mountaintops or in the Arctic, might not have a nice habitat to live in. If the Earth keeps getting warmer, up to one fourth of all the plants and animals on Earth could become extinct within 100 years.So becaus of global worming we have been

It took millions of years to recover. The first great mass extinction event took place at the end of the Ordovician. period.The second was the Late Devonian period. Next was the end Permian mass extinction.Then there was the Triassic mass extinction. Lastly, the 5th extinction was the end of the Cretaceous period which was 65 million years ago,it is famously associated with the lost and extinction of the dinosaurs. Most of these extinctions that happened scientist aren't really sure about but here are possibilities that they believed they could have happened. They could have died from climatic change, diseases, meteors, the lost of food and plants,volcanic eruptions,and other freak
