As grasslands and forested areas increase in number, many people are looking for a way to preserve their ecosystems for future generations.
Mongolians are now a part of the mix.
A recent study published in the Journal of Agricultural and Food Chemistry, for example, found that grasslands can provide a new habitat for a new species of mongrel.
The researchers from the University of California, Davis and the University in California, Irvine used satellite imagery to map the distribution of grassland and forest habitats worldwide.
They found that in the western United States, grasslands have grown from only a few dozen to nearly 4 million hectares (8.5 million acres) since 1950.
In Africa, grassland covers about half the continent’s land area, and it is growing at a rate of nearly 50 percent a year.
While the grasslands of the tropics are not expected to support any new species until the 21st century, grass is slowly replacing forest as a major food source for the global population.
Many scientists believe that the rapid spread of grasslands is a major factor in the rapid growth of the global livestock industry, as grasslands provide a good home for animals that would otherwise be lost to hunting and fishing.
