The heatwave that devastated North America last week consumed the lives of a billion animals. Anticipating this destruction on Canada’s Pacific coast, scientists have drawn attention to ecosystems exposed to sudden changes in temperature. In western Canada and the northwestern US, the temperature remained above 40 degrees Celsius for five days.
This broke many records, at least 500 people lost their lives in the province of British Columbia. Hundreds of forest fires also raged which are still going on. At the same time, Christopher Harley, a marine biologist at the University of British Columbia, estimates that billions of aquatic creatures may have died in this scorching heat.
It is estimated from the dead muscle shales scattered on the shores of Vancouver. Snails, sea stars and clams were rotting in the water. This will also affect the quality of the water as mussels and clams help filter the water. Mussels cannot tolerate temperatures above 30 °C.

Due to these, sunlight reaches the bottom and other organisms can flourish. Worryingly, reproduction is slow in organisms such as starfish and clams. In such a situation, it may take a long time for their population to flourish again. According to Harley, his other companions have also informed about the death of sea anemone, rock fish and oyster. Experts say that the province will have to be prepared for such a sudden change due to climate change.
According to the report of the Guardian, heatwave may come again in the coming week. Harley fears that many species will not be able to tolerate this change. It will be difficult to say what will change in the ecosystem.
