In the future‚ global warming will cause horrible effects such as heat waves‚ droughts‚ floods and storms. Due to these events some of the world’s poorest countries will suffer terribly by disrupting food production‚ important major animal species‚ and many habitats and ecosystems will be destroyed. Even with all of this research‚ the

Australia has been minimal compared to that in other countries because: * Australia is a stable continent * Australian homes are well constructed * Australia is not a densely populated nation. 5 * Floods Few parts of Australia are immune from flooding (see pg.46). Areas where floods most commonly occur in Australia include northern Australia (associated with monsoonal depressions in summer)‚ coastal areas of eastern Australia (associated with low pressure systems and fronts).

nutrients. (ii) Harm to fisheries: As the soil is eroded‚ it accelerates siltation in dams‚ rivers‚ and the coastal zone. The increased sedimentation harms downstream fisheries. (iii) More floods and droughts: Because of deforestation‚ there is no regulation of the flow into rivers. As result‚ floods and droughts alternate in the affected areas. (iv) Habitat loss of wildlife: Butterflies‚ migratory birds‚ wild animals suffer due to the loss of their habitat. (v) Extinction of some species:

Introduction A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods‚ volcanic eruptions‚ earthquakes‚ tsunamis‚ and other geologic processes. A natural disaster can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover. An adverse event will not rise to the level of a disaster if it occurs in an area without

Thus‚ drought effects are one of the major concerns being addressed by researchers in this region. climate modellers have predicted a large increase in temperature for this region‚ which could lead to even drier conditions and enormous stresses on vegetation in the western Canadian boreal forest. This type of impact was observed following the 1988 drought it experiences‚ when there was a die-back of aspen over extensive areas of the aspen parkland in Western Canada. Associated with this drought was

Natural Disasters We have all seen the awful effects of a flood or an earthquake - if we’re lucky only on the news. About 75 percent of the world’s population live in areas affected at least once by earthquake‚ tropical cyclone‚ flood or drought between 1980 and 2000 (Reducing Disaster Risk UNDP report‚ 2005). What causes natural disasters? First we need to get a bit technical. Natural hazards and natural disasters may sound like the same thing but there is a small but vital

Deforestation Plants give us oxygen which is the most important thing for our survival. They undergo a process of photosynthesis in which they give out oxygen and take carbon dioxide. Plants consume the air‚ sunlight and the carbon dioxide we breathe out to make food and oxygen. So if trees are cut‚ plants will not produce oxygen and the concentration of carbon dioxide will increase. Increase of carbon dioxide in the air is harmful for human beings and also disturbs the water cycle and hence the
