Communities with less economic and sociopolitical power often lack the resources to get involved in environmental advocacy.

Environmental history increasingly highlights the ways in which the middle-class environmental movement has fallen short and left behind entire communities. Interdisciplinary research now understands historic inequality as a lens through which to predict future social developments in the environmental sphere, particularly with regard to climate change.

The United Nations Department of Economic and Social Affairs cautions that a warming planet will exacerbate environmental and other inequalities, particularly with regard to: " a increase in the exposure of the disadvantaged groups to the adverse effects of climate change; b increase in their susceptibility to damage caused by climate change; and c decrease in their ability to cope and recover from the damage suffered.

Declensionist narratives[ edit ] Narratives of environmental history tend to be declensionist, that is, accounts of progressive decline under human activity. In environmental debate blame can always be apportioned, but it is more constructive for the future to understand the values and imperatives of the period under discussion so that causes are determined and the context explained.

Mural in the burial chamber of artisan Sennedjem c. The claim that the path of history has been forged by environmental rather than cultural forces is referred to as environmental determinism while, at the other extreme, is what may be called cultural determinism. An example of cultural determinism would be the view that human influence is so pervasive that the idea of pristine nature has little validity - that there is no way of relating to nature without culture.

The tools are those of both history and science with a requirement for fluency in the language of natural science and especially ecology. Cambridge University Press, Hughes, J. LaFreniere, Gilbert F. An Abridgement.

Donald Hughes has also provided a global conspectus of major contributions to the environmental history literature. Journal of Historical Geography. If you change the subscripts, then you are changing what chemicals are involved, not ratios at which they react.

These endeavors involved changing the shape of a substance without changing Doing chemistry involves attempting to answer questions and explain Read chapter 5 Changes in the Chemistry of the Atmosphere: How can we understand On integrated aquaculture the persistence H5 and H7 Avian influenza virus strains are feared but the inverse relationship to temperature and salinity of water reduces this fear of risks to human health Brown et al.

Saline water intrusion: Climate change effects result to sea level rise and increase in salinity intrusion upstream that affects fresh water culture practices. Sea level rise and saline water intrusion will also impose ecological and habitat changes, including the mangroves that serve as nursery grounds for the many euryhaline species.

Changes in monsoon patterns and occurrence of extreme weather events: Effects from typhoons, hurricanes and unusual floods increased heavily resulting in large economic losses large storms damaging cage culture systems in rivers and lakes resulting to large escapes of finfishes Soto et al. Climate change also causes severe weather variability patterns and poor water quality plankton bloom resulting in water pollution and other damaging run-off due to flooding that cause structural damage, escapes and loss of livelihoods of fish farmers.

It also causes major effects on fish spawning, migration and seed availability for large farmers. It can also lead to less water retention time in non perennial water bodies Goswami et al.

Other ingredients used in aquaculture: The use of raw materials, such as soybean meals and corn meals for the production of biofuel instead of usual feed production results to more economic and social challenges, specially in the aquaculture subsector. Effects on disease: Increased temperature due to climate variability, stress the fish and facilitate diseases.

In the freshwater aquaculture, increased uptake of toxicants and heavy metals through accelerated metabolic rates from increased temperature by cultured filter feeding mollusks is suggested to be plausible Ficker et al. Consequently leading to food safety measures and certification issues. Impacts on biodiversity: The impacts of climate change on biodiversity from exotic species have resulted to competition for food and space with the indigenous species, in the alteration of habitats Collares-Pereira and Cowx, , the transmission of pathogenic organisms as well as genetic interactions through hybridization and introgression Araguas et al.

It is also stated that the genetic make-up of aquaculture stocks has been altered by selective breeding practices and genetic drift thereby resulting in some instances to severe inbreeding. Such alterations would potentially impact the gene pools of the wild species with their culture counter parts through genetic alteration, between the escapes and their wild individuals.
