The certification of banana production is an important way to help conserve the tropical rainforest ecosystem and protect the livelihood of people who live there . Prior to any tactical decisions , managers will want to assess the conditions for burning within the specific ecosystem context in order to determine if a cool burn is possible . The aim of this investigation is to allow a better description of these processes between ecosystem and atmosphere based on Relaxed Eddy Accumulation ( REA ) measurements of CO2 and 13C fluxes . This strategy could bring wholesale changes to marine ecosystems : to take one hypothesis , the southern North Sea could become dominated by jellyfish , rather than commercially exploitable fish , as the top predators . River engineering is also the main cause of destruction of the river ecosystems : changes to the physical habitat , river channels and banks , for example , are implicated in 93 per cent of freshwater fauna declines in North America . At the invitation by the Government of Botswana ( GoB ) , the International Union for the Conservation of Nature ( IUCN ) evaluated the proposed project and found it ill-conceived and detrimental to the ecosystem and communities of the Delta . Every urban centre poses a threat to the arid zone ecosystem through its pattern of urban activities , few more so than tourism , because urban dynamics are not likely to be ecologically coherent with the dynamics of an arid zone ecosystem unless there is strategic , rational intervention . The greater San Antonio area has a particularly sensitive ecosystem built upon hard limestone bedrock and thin soils.The limestone 's faults and sinkholes allow rainwater to drain directly into the aquifer without the benefit of passing through soil , which naturally filters out sediment and urban runoff pollutants . The consultants present other scenarios that would cause less damage to the ecosystem and the humans living in it .
