The Brazilian government has to develop it's natural resources in order for it to be able to develop. This will mean a continuation of the rainforest destruction that has seen 18% of the Amazon disappear already. The Brazilian government has to put the needs of the Brazilian people before global environmental concerns.
The destruction and devestation caused by a natural disaster varies according to which country it hits. Countries that have a higher GNP are less likely to have a high mortality rate from the disaster and less likely to suffer a large economic impact.
