According to observations, for the ten-year data collection period, the average increase in size is within two percent. Such an increase is extremely rapid in terms of evolution. In the past, such an increase in size has also been observed, dictated by the same or similar temperature reasons, but this has been happening for hundreds or thousands of years.

Naturally, the explanation for which is global warming and the increase in average annual temperatures, which in turn affects the soil substrate for flowers and plants, ecological news sought for you by eko.com.

According to researcher David Ward, the percentage of wild geese (Branta bernicla nigricans) that do not fly south to traditional wintering grounds south of California, on the Mexican peninsula, has increased and in 30 years the number of geese is already a whole. 30% or about 40,000 wild geese, up from 4% thirty years ago. ограничители качествени за трева
