Plants and animals are declining due to warmer temperatures and water shortages, scientists said Monday, warning that could have profound implications for food production in the coming years.
"The worst case scenario ... is that the crops and animals shrinks enough to have a real impact on food security," Associate Professor David Bickford, National University of Singapore Department of Biological Sciences, said.
Bickford and his colleague Jennifer Sheridan examined all fossil records of dozens of studies have shown that many species of plants and creatures such as spiders, beetles, bees, ants and crickets decreased over time compared to climate change.
You mentioned an experiment that shows how the shoots and fruits are 3 to 17 percent less for each degree Celsius of warming in a variety of plants.
Each degree of warming is reduced by 0.5 to 4 percent of the body size of marine invertebrates and fish 6-22 percent.
"The survival of small individuals may increase with rising temperatures and drought could lead to smaller children, leading to smaller average size," they write in their article, published in the journal Nature Climate Change on Monday.
"The effects can range from food resources become more limited (less food produced by the same amount of land) to wholesale customers with the loss of biodiversity and the possible catastrophic cascade of ecosystem services," says Bickford.
"We have not seen much effect yet, but since the change of temperature even more, these changes in body size is much more pronounced -. Even have implications for food security"
