Lake Erie provides drinking water to the region, habitat for
wildlife, and it’s a mecca for fishing and recreation.
However, microbial pollution in the lake threatens human and
ecosystem health, as well as local economies and future economic
The use of perovskites as light-harvesting layers has become an
important technology for low-cost solar cells that are capable of
converting more than 20 percent of sunlight into electricity. The
basis for such solar cells are the properties of lead-based hybrid
perovskite layers, including very high absorption of solar light
and great electrical properties.
Expanding urban population and climate change continue to
challenge the development of sustainable cities. The increasing
scarcity of urban land and competing demands over how land is used
make it essential that innovative planning solutions appropriately
balance the storm water management, energy production, recreation,
and other societal priorities.
Research on the adverse effects of air pollution on human health
and environment has benefited from monitoring stations that
routinely collect data on air quality. However, monitoring networks
are sparsely located and preferentially placed.
In addition to the most basic need for safe drinking water, the
availablity of good quality freshwater affects nearly every aspect
of modern life, including energy resources, food production,
transportation, manufacturing, and recreation, as well as
supporting ecological well-being and the ecosystem services on
which life depends.
Climate change is the single most pressing global issue facing
society today; one estimate suggests that a climate-induced global
sea level rise of just one meter will cost 28 trillion US dollars
to world economies.
