Climate change is real and is affecting our environment in alarming ways.
A new study suggests that climate change is affecting the polar bears by melting the sea ice, which is their most important food source.
A team of researchers conducted the study and found that because the ice is melting at an alarming rate, the polar bears won’t be able to find enough food on land to replace the diet they are currently on, which consists mostly of animals they hunt in the water.
The new study contradicts a previous one which suggested that even though the polar bears won’t be able to find food in the water, they will very well survive eating berries, bird eggs and other food sources found in land.
Karyn Rode, a wildlife biologist from the United States Geological Survey and one of the study’s lead authors, explained that there are polar bears that survive on land food, but their number is limited. The food sources found on land cannot replace their current marine diet, which consists of mammals like seals, says Rode.
Rode published the findings of her study in the journal Frontiers in Ecology and the Environment on Wednesday.
The main purpose of the study was to research the polar bears that are becoming more and more dependent on the food sources found on land.
The researchers wanted to see if previous studies, which suggest that polar bears can actually survive even though their natural habitat is slowly melting away, are accurate.
According to their findings, the food sources that can be found on land cannot replace the polar bears’ current diet.
However, some scientists do not agree with Rode’s new study.
One of those scientists is Robert Rockwell, an expert in ecology at City College of New York, who has been conducting studies on polar bears for more than 40 years.
According to Rockwell, he has studying polar bears for so long that he witnessed how their eating behavior is adapting according to their needs.
Rockwell said that he has seen polar bears feed on bird eggs, like goose eggs and young caribou.
