Ecosystem Canaries Warn Experts About The Collapse Of An Ecosystem
Coal miners used to check for poisonous gasses underground with canaries. These days, scientists use “ecosystem canaries” to see how an ecosystem is doing. The species are not actually canaries, perhaps not even birds to begin with. However, they are species that have begun dying before the collapse of the whole ecosystem. In general, they tend to reproduce slowly and do not fare well when it comes to competing for resources. Similar to the keystone species, they are not exactly the most important parts of the ecosystem. However, they can signal its current conditions.

Animal And Plant Range Shifts Indicate Climate Change
The shifting of plant and animal ranges happens to be among the first signs of climate change. A range refers to the area where the species occur naturally. It is determined by factors such as humidity, rainfall, temperature, and other natural attributes. However, climate change will impact these factors and alter the range of many animals. Grizzly bears are now heading north and stumbling into polar bear country. According to scientists, half of living species are now moving elsewhere. This is definitely concerning news that should alarm all of us.
