There is also negative impact on the agricultural section and water sector are likely to be considerable. Staple food crops such as maize, sorghum and beans etc. are the crops of which are likely to decrease, thereby threatening national food security. That Global warming is affecting the water in the country of Swaziland creating a shortage of it and in some area therefor causing drought. Source 3: Life between the
Salinity is one of the most important factors that influence greatly plant growth and productivity in arid and semi arid regions (Jamil et al. 2005). Salinity stress caused losing yield in common beans (Läuchli, 1984). The results of Talaat (2015) showed that common beans plants were grown in saline conditions showed a decline in productivity, membrane stability index. Salt stress in common beans caused a several growth limitation so that bean can tolerate below 50 Mm NaCl but higher concentrations caused dramatic reduction in growth and yield (Gama et al., 2007).
Environmental health is crucial to the future of Earth therefore humans need to be aware of daily actions that may have a much larger effect than expected. If humans continue to consume animal products, including eggs and dairy products, the overall health of our environment will continue to diminish due to the detrimental effects of the multistep process required for the production of these products. Such effects include the massive amount of resources used, the decline of natural habitats, and an increased production of greenhouse gases--which causes global warming. Though the extreme importance of environmental health, humans tend to focus on issues such as unequal rights, racism, starvation, wars, however, none of these issues will matter if there isn’t actually a healthy planet to live on. Equal rights won’t be needed if there are no people to need them.
Introduction: Today it is thought that global warming is a serious problem in our society. Scientist say that global warming has caused an abundance of serious matter like polar bear population decreased and extreme weather conditions. In this essay, global warming will be discussed and the cause and effects of it, as well as to what we can do to help prevent it. Ultimately, a conclusion will be raised answering the focus question, “Will global warming be the end of the human race?” First Section: Global Warming and its Causes Global warming is an unnatural warmer of the earth. Global warming is when the average temperature of earth's atmosphere and oceans rise.
Global warming, also referred to as climate change which means a current increase in temperature of the earth’s surface as well as it’s atmosphere due to rising levels of greenhouse gases. It is a big issue of the atmosphere on the earth. It is caused by the human as well as by natural events. Human is the causes for emission of greenhouse gases such as methane, nitrous oxide, and carbon dioxide. Over the past 100 years, the earth has warmed by about 1°F.
Environmental Health challenges is a varies problems that face health in developed and undeveloped countries like: air pollution, contamination of water and soil, acid rain, chemical hazards, disease vectors (dengue fever, malaria, zika), radiation etc. there is collection of studies have been conducted about numbers of mortality and morbidity around the world and the main cause of it is environmental health challenges. world health organization reported 7 million deaths around the world every year because of air pollution. The biggest load falls on (low-income country) and (middle-income country) like: south east Asia and western pacific region. (WHO,
The current warming trend is of particular significance because most of it is very likely human-induced and it is proceeding at a uncontrollable rate. It causes Rise in Sea level which Global sea level rise unprecedentedly in the 10 years. The rate currently in this few years, however, is nearly double that of the last century. It leaves low lying countries like the Netherlands, Micronesia and small pacific islands at risk of being completely swallowed by the sea. As of now certain countries are vanishing in a twinkle of an
The glaciers are melting and shrinking and the ice on the rivers and the lakes is melting faster and earlier than the actual season. The melting of glaciers and ice on the sea is resulting in rise of the global sea level. Since 1880, the level of sea has increased about 8 inches, and at this rate it is expected that it will rise another 4 feet by the end of the 22nd century (Lindsey). In the coming years, storm heaves and the tidal waves can combine with the rise in sea level and subsidence of land that can lead to increase of flooding in many areas of the world, and due to deforestation and lack of other precautionary measures in many areas of the world, we will not be able to stop these floods. The water in the oceans take a huge amount to time to respond to the warm conditions at earth’s surface.
Climate change and global warming have always been an issue, but in recent years, the global temperature has increased significantly. The main cause of climate change is the expansion of greenhouse gases in the atmosphere, which are omitted by humans. Due to humans clearing land for agriculture and factories, this has increased the concentration of carbon dioxide in earth’s atmosphere. The large amount of greenhouse gases in earth’s atmosphere, cause for heat to be trapped in the atmosphere more easily, which eventually leads to sea level rise, more evaporation, less precipitation, and overall, warmer weather conditions. Some regions will become dryer, due to less precipitation, while others become more wet, due to more than average rainfall.
Characteristic of global warming and its cause Global warming is an issue defined as increased ocean temperature. In the strict sense, it is applied for a climate changes between 20. and 21. century. In a fact global warming affects ferocious fire, drought, rising seas and decreasing glaciers, storms, floods and economy. An issue is a velocity of the concentration of the carbon dioxide in the atmosphere. This initiates rise of the temperature.
