Tiny or large, smelly or poisonous, there are many kinds of frogs and are excellent indicators of the quality of the overall environment.

transportation to use to go to work. Likewise, by employing the use of past and present data and trends, policymakers can make predictions of the future in order to create more effective policies, as well as find better “prescriptions” to solve existing problems (Lecture, 4/1/2010). There are existing neo-Malthusian theories, such as those made by Donella Meadows, et al., that the current trends, including increased population growth, subsequently

2. Identify a broad range of current environmental health problems likely to be exacerbated by climate change. How might existing public health practices be altered to anticipate these effects of climate change? What other key sectors (beyond health) should be engaged? Current environmental health problems that will likely exacerbate due to climate change include changes in air and water quality, and increase in parasite growth and chemical pollutants. • General climate change: cardiovascular disease

which causes unsanitary conditions and accelerated erosion. Public health and environmental problems occur because Mexico does not have strong environmental policies. Projects to help with these issues have been put into place to help improve water quality. Most of the runoff that is collected in the watershed eventually makes its way into the Tijuana Estuary and along the coastline which can result in economic problems because of beach closures. These areas are also home to many endangered species
Salinity is one of the world’s most serious environmental problems in agriculture. It is estimated that about one-third of the world’s cultivated land is affected by salinity (Perez- Alfocea et al., 1996). The National Academy of Sciences of the USA includes salinization of soils and waters as one of the leading processes contributing to a possible worldwide catastrophe (Francois and Maas, 1994). The increasing world population, especially in arid and semi-arid regions, food shortages, and land scarcity
