"Danger to human populations from environmental events is both increasing and decreasing." Human populations all over the world are in danger from environmental events

Extracts from this document...

Introduction

"Danger to human populations from environmental events is both increasing and decreasing." Human populations all over the world are in danger from environmental events. These events have the potential to harm humans, possessions and income. Environmental events or hazards are extreme conditions that can cause injury, loss of life, loss of agriculture and the environment, damage to property and housing. There are a number of variables that influence the level of danger the community is faced with. These factors include; the magnitude and frequency of the event, the vulnerability of the community and the resources available. These factors can both increase and decrease the danger to human populations. On a global scale the frequency and magnitude of environmental hazards is both increasing and decreasing, depending on the particular hazard. ...read more.

How well the community can prepare for, and cope with the hazard determines their danger level. In general, communities living in 3rd world countries are at a greater risk of danger than people living in 1st world countries due to their dense populations, low level of education and poor economy. Many 3rd world communities have poor housing arrangements that do not protect the people and can be completely destroyed by environmental events. They also do not have insurance to protect their assets. This means that they take much longer to recover from an event, as they cannot afford to rebuild their community. In developing countries survival of people relies heavily on crop production, but often they do not have the knowledge or technology to protect these crops from environmental hazards. ...read more.

Conclusion

The engineering developments in developed countries, can greatly lessen the impact of environmental hazards and protect the community. This is evident in London, where barriers were built in the Thames River to protect the surrounding community from floodwaters. Also, In Japan buildings have been built which have large springs underneath them, which absorb the impact of earthquakes. Overall, communities living in 3rd world countries are far more able to cope with environmental events, and so the people are at less risk of danger. As the economy of developed countries increases, they become more technologically advanced and can prepare for and recover more quickly from hazards, decreasing danger to human populations. However, as underdeveloped countries get further into dept and population growth increases, they become more vulnerable to hazards and therefore the danger to humans increases. Therefore, I agree that danger to human populations is both increasing and decreasing. ...read more.

As the amount of effected plants increases, as does the insect count, they can spread the disease to other plants, which are not yet infected. This outbreak in plant disease, can also affect trees and shrubbery, in which some animals may rely on to eat as food.
