The main cause of food insecurity in Africa is the inability to of citizens to gain access to food due to poverty. Many factors have contributed to this problem which leads to an increase in the prevalence of food insecurity (Mwaniki, 2015, p. 1). Factors contributing to food insecurity include: • Drought and other extreme weather events. In recent times it has been seen that major food crisis has been a result of “drought or extreme weather conditions’’, this impacted negatively on crop harvests which in turn caused a food shortage and an increase in food prices (Harvesthelp, 2012). • Pests, livestock diseases and other agricultural problems.
Global warming, the ozone layers being damaged, deforesting, rivers drying up, unbalancing ecosystem and different kinds of pollution lead to certain climate change. Although all the causes of climate change are made by humans, it is hard to restore the original global balance situation. Climate change becomes a serious ailment of our mother earth. The earth, our home,
Water shortages will impact both health and agriculture directly” (Gilman). With the expanding effect of climate change throughout the world, water shortages have been an ongoing issue in many countries. As the author mentions, these numbers drastically
Homero Castro Ms. Cabaj English IV, 3rd period 12 February 2018 Global Warming Global Warming is affecting the entire world. The issue of global warming is important because it’s affecting everyone. This problem is controversial because some people believe that that global warming isn 't real and others believe it is. There is evidence that global warming is real because some scientist agree that the earth 's rising temperatures is due to all of the pollution. My opinion on it is that it is clearly real and we need to do something to stop it.
The water cycle’s process depends on the weather and since it is constantly changing dramatically there is a risk of radical droughts and drastic rain. When water evaporates from the land and sea, it usually enters back into Earth as rain or snow however, due to temperatures increasing there is additional evaporation occurring which means we are receiving less water from the atmosphere. Droughts can not only cause drinking water to be scarce but it can also kill crops and farm animals as well as turn fertile land to desert (Woodward, 2008). In addition, rising temperatures has allowed air to store more water vapor which can lead to intense rain storms. An excess amount of water can create the risk of flooding and unfortunately, most of the water ends up drifting into rivers and streams doing little to dampen soil (“climaterealityproject.org”).
The excess carbon dioxide in the atmosphere is related to climate change; this affects the environment through increased temperatures, extreme events such as droughts and floods as well as a rise in sea levels (Lebon, 2009). When volcanic gas enters the atmosphere, the water droplets formed become contaminated with that substance and when it rains, the rain that falls is acidic. Acid rain causes negative effects to surrounding plant life as it is corrosive making it useless to animal species that rely on it as a food source (Lebon, 2009). Other environmental impacts associated with tectonic movements are earthquakes. This kind of deformation is classified as natural disasters and causes destruction through flooding, rifts and collapsing of large buildings in cities.
The air isn’t safe to breathe in certain areas. Global warming is responsible for all this. B. Thesis: The causes of global warming and climate change are because of increased emissions of greenhouse gases, and the effects of this are rising temperatures and more severe natural disasters. II. Body A.
Although some skeptics around the world believe that climate change is a hoax and unscientific, many respected scientists have concluded that environmental changes brought around by humans have altered the patterns of rainfall around the world, resulting in serious consequences. Narration Climate change itself is a manmade alteration to the earth’s natural homeostasis. By instigating climate change, humans have made it so a wide variety of problems have become apparent. One of many complications is the change in precipitation patterns, which can lead to flooding via extreme storms and can even cause extreme droughts. This problem is a serious one as every year, billions of
Climate change is the whole picture, not just one part. It includes global warming, but also the aftermath of global warming. Examples are change in weather, increase of natural disasters, melting glaciers, and more frequent droughts (“The World Is Getting Warmer.”). The world is overlooking climate change and this will inevitably lead to the extinction of mankind. Humans are by far the biggest cause of climate change right now.
However, there is a very harmful system known as fracking. These companies are not noticing that this technique does the complete opposite. There is a big fear that changing to cheap fracked natural gas to replace coal could backfire and could worsen the situation even further. Environmental groups are afraid that if hydraulic fracturing were to happen, they believe that contaminating underground water supplies could affect global warming 20 times more (Davenport 1). Fracking contaminates the underground soil which has its consequences.
The increase of population cannot keep up with the amount of water distributed. Some causes of water poverty are deaths from diseases caused by dirty water which are preventable. Although, lack of access to clean water continues to complicate life for people in poverty. At least 1.8 billion people use a drinking-water source contaminated with fesses. Water is a basic human right.
temporary impact, since plants and animals depend on water just like us, we may lose a lot of food supply. However, drought can impact our environment in the most serious way, and it will last very long even when the drought is over. The permanent impact that created by drought may include such as, loss of wetlands (moisture), wind and water erosion of soils, poor soil quality, migration of wildlife, and more wildfire (Drought in California). Even some of the effects are short-term damages, and the conditions will return to normal when the drought is completely over. However, the migrant of wildlife will become permanent environmental damages because our soil will lose its moisture and quality that includes the loss of wetlands that can lead to a permanent loss of biological productivity.
Climate change is more serious than we take it. If it continues, everyone will parish. Climate change affects us in many different ways. It causes animal population numbers to decrease, slows down transportation to the north, and causes flooding and the rise of the sea level. Global warming exists, and it is not only affecting the environment.
