It brought an increase in food supply, changes in lifestyle, and changes of the treatment of the planet. The Green Revolution was caused by a need for improvement an it had both negative and positive consequences, such as an in food supplies, new lifestyle changes, and treatment of the planet. The green revolution was caused by a need for improvements. Documents 3 and 4 both illustrate that prior to the revolution, there were too many diseases
There are many things that happen during climate change. The oceans are warming leaving the glaciers to melt, and overall the world’s natural state is disappearing. If that wasn’t enough, the population is constantly growing. ‘Human activity is causing irreversible harm to the climate system and environment’ so it should be up to each human to help to combat it and adapt to it. (Cao, 2008).
During the Cold War era from 1945-1980, the environment took priority in American society. Awareness about the need to preserve the planet culminated in a nationwide Earth Day which proved the growing worry about the lack of sustainability found on Earth. Other environmental factors required immediate action to be taken before the detrimental effects of humans and their role in society would be too much for this world to handle. Although there are a variety of factors that raised awareness about the dangerous environment on earth, it was ultimately the implementation of the first Earth Day, tempting climate in the Sun Belt, and the environmental movement by Rachel Carson that brought the awareness to harsh environmental factors in the late
The ice from glaciers, the ice sheets and permafrost are already melting and will probably continue to melt at a higher rate in the future leading to rises in ocean levels (IPCC, 2014). Furthermore, it causes the emission of methane (also a GHG), stored mostly in the Arctic regions (Shakhova et al., 2007) which in turn leads to increased heat in the atmosphere, further aggravating climate change. GHGs cause the oceans to contain increasingly more acids, which damages coral reefs and negatively influences the amount of CO2 the ocean can absorb (IPCC, 2014). Weather conditions are becoming progressively extreme and a rise in floods, hurricanes and temperatures can already be measured and will further increase in the future (USGCRP, 2014). Weather incidents could destroy forests and swamps, which causes less CO2 to be absorbed naturally.
However, one of the lesser understood and studied effects of climate change, is the re-emergence of deadly diseases that pose an enormous threat to the well being of our economy. As climate change continues to intensify, polar ice caps and frozen landscapes continue to melt. However what many people overlook, is the fact that there lies a large number of diseases and bacteria frozen within that ice. As the climate intensifies, the risk of these diseases reemerging increases significantly. This means deadly ancient diseases such as the black plague or smallpox may reemerge similarly to the 18th and 19th centuries.
After the Green Revolution, however, food supply surpassed world population significantly (doc#2). This means that a clear cause for the Green Revolution was the need to increase food supply. The world population did not have enough surpluses, leading to hunger and poverty. The Green Revolution was created to sustain the world population. A useful additional document would be data from a graph about food supply and human population specifically from developing countries, in order to see if the Green Revolution truly helped these areas.
Global warming plays a large part in the cause of drought. A. Global warming causes many deadly effects that people often ignore, as they don’t believe the reason of effects is global warming, but global warming truly causes many problems. 1. Global warming is causing rising seas which dramatically effect all sorts of different things.
In the US alone, the Office of Response and Restoration of the National Oceanic and Atmospheric Administration (NOAA) responds to over a hundred oil spills each year (NOAA). While spills happen on both land and water, ocean spills are much more difficult to contain and recover from. They happen easily, almost too easily, either caused by carelessness, accidents, or natural disasters, and their negative environmental impacts could take decades to recover from. It seems like as long as humans are still depending on oil, spills will continue to wreck havoc on marine life. Oil harms marine animals both physically and chemically.
World wildlife stated that Humans and animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. (Source 5) . Meaning that the longer we let it climate change affect our planet the higher the chance of the increase in tides, hotter heat storms, and drought.In the next several decades, storm surges and high tides could combine with sea level rise and land subsidence to further increase flooding in many regions. According to Nasa, Sea levels continue to rise after 2100 because the oceans take a very long time to respond to warmer conditions at the Earth’s surface.
One of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.
Climate change will affect communities in the north by destroying the best way to transport things. Finally, the sea level rise and flooding is a big problem people-wise. Flooding causes millions in damage that sometimes cannot be reversed. Flooding is encouraged by climate change because of the increase in moisture trapped in the air, and rain happening earlier in the year and falling on still frozen ground. Houses being destroyed by increased water also leave people homeless and cost a lot to fix.
