A University of Michigan ecologist found that biologically diverse streams are better at removing nitrate, a nitrogen compound pollutant, than less rich waterways. Niche partitioning, where each species occupies a unique habitat, increases the stream's absorbent sponge-like ability to clean pollutants.
A national study found that 28% of US women with two or more children have children by more than one man. This prevalence is common among minority women, those living without a partner, and those with low income and education. Multiple partner fertility is tied to marriage and divorce rather than single parenthood.
Despite 50 years of rapid population growth, the world has successfully produced enough food and reduced poverty. Factors contributing to this include the green revolution, increased investments in education, and urbanization, which have allowed cities to absorb growth without triggering mass starvation.
