If you would notice, increased global temperatures, water shortages, habitat loss, sea level rise, contamination of water quality and loss of quantity has all been mentioned within each of the sub cycles above. Each cycle has to be kept within perfect balance should we want to avoid anthropogenically induces environmental impact. The trend being that these sub cycles have been impacted upon by anthropogenic activities related to modern environmental impacts. Needless to say that these cycles find balance sometimes resulting in natural disasters leading to social impacts. Since these sun cycles are inter linked, an imbalance in one cycle could throw the others into imbalance as well.
Ecosystems are already showing negative impacts under current levels of climate change. This essay will argue that climate change is a huge threat to biodiversity and will also focus on the natural cycle and the modern day cycle change. Firstly, it will define and discuss the natural climate change cycle. Then secondly, it will analyse the effects of human activities on the climate that are rapidly changing it. Finally, it will examine the effect climate change had the now extinct Golden Toad.
Introduction This paper describes the potential effects of drought and the responses of the aquatic biota to the drought situations. The focus of the paper will be principally on the response of the invertebrates and fishes to seasonal and supra-seasonal droughts. As said by Bradshaw & Holzapfel (1988), Corti, Kohler & Sparks (1988), and Webster et al. (1996) the situation remains the same for stagnant waters, floodplain ponds, and lakes respectively. The drought have impact on both human and also on the aquatic ecosystems.
Humans are impacting the world’s biodiversity in many negative ways, by the things that they do to get what they want and all at the loss of the natural environment. If humans carry on the way that are soon nothing will be left on this earth which is extremely sad to think about. Making small changes could really make a big impact. Over harvesting has possibly got the greatest effect on biodiversity and the environment. Removal of an organism from its environment can often leave irreversible impacts on the environment its self.
The necessity would serve to maintain the region richness. the ecological parameters sources to protect and maintain the biodiversity richness however due to few anthropogenic influence includes habitat fragmentation, mining, natural influence such as alien species dominance, impact of development projects e.g. wind mill and wind farms, over exploration and most vital of all is climate change, over grazing and brazing by cattles may also add to the risks or threats for the loss of biodiversity richness. The purpose of conservation of this area is because of the reason that the area is known to have important and rare indigenous species viz. Commiphora wightii (Arn.)
Recent changes in climate have already had significant impacts on biodiversity and ecosystems in certain regions. As climate change will become more severe, the harmful impacts on ecosystem services are expected to outweigh possible benefits, such as a longer growing season, in most regions of the world. Climate change is expected to exacerbate risks of extinctions, floods, droughts, population declines, and disease outbreaks. Many drivers affecting biodiversity are stronger today than they were in the past and are also occurring together. Because exposure to one threat often makes a species more susceptible to another, multiple threats may have unexpectedly dramatic impacts on biodiversity.
Abstract: Introduction: Environmental impacts and issues have attracted researchers over the past few decades. Studies related to the degradation of the environment and the possible improvements have created quite a stir among the environmentalists and the scientists, shifting their focus from inventing new technologies to curbing the environmental impacts caused by them. Increased purchasing power parity (PPP) is closely related to the energy usage and heightened levels of pollution. Constant efforts are made to increase the energy efficiency, lower the negative environmental effects caused due to increase of wealth and the flow of information and global communication. Lighting has been the cause of quite a few environmental impacts.
As a result of human activities, the environment is in many ways, degradation, and global warming will accelerate these degradation. (1) because of the high temperature melting glaciers, water thermal expansion, causing the sea level to rise. Sea level rise will be a serious threat to coastal areas, may inundate low-lying coastal areas, serious impact on human activities. (2) climate change caused by global warming will lead to great changes in water supply in many places, the availability of fresh water will be greatly changed. The temperature increase means down to the water will be evaporated, if there is more rainfall to supplement evaporation, is not What impact.
Biological diversity defines according to article two of The Convention on Biological Diversity (CBD) which entered into force on 29 December 1993 as the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems. Many studies try to estimate the number of living species in the earth starting from 15,000 describe species and 500,000 estimated species (Poinar, 1983) then from 3–5 million (Tangley 1997) and 50 million (May 1998) then last but not least 11 million with around 18000 species described each year (Chapman 2009) .but all studies gives an estimation
Although these conditions are increasingly under threat. In addition to the growing demand that freshwater supplies face for purposes like agriculture, energy, and human settlements, the effects of climate change are exacerbating changes to the hydrological cycle. Climatic changes lead to permanent shifts in freshwater conditions, depleting biodiversity and impacting the proper functioning of freshwater ecosystems, as well as manifesting themselves in more frequent and severe extreme events such as drought and
