Which are the different areas that are posing threats due to various natural and man made disasters?

Natural and man-made disasters can contribute to the threats posed to the environment. Firstly, earthquakes, hurricanes, tsunamis and many more natural disasters will cause significant damage to the ecosystem. For example, an earthquake or a hurricane can cause animals and plants to die out. Man-made disasters such as those caused by nuclear bombs can caused effects like radiation which will also wipe out the wildlife in the area.

Global warming is another aspect. Natural disasters such as volcanic eruptions can cause volcanic ash, gases and sediments to be ejected out. These will, in the long term, cause global warming. It may react with the ozone layer, resulting in big holes in them and letting UV rays from the sun pass through it onto Earth's surface. The gases produced, such as carbon dioxide and sulfur dioxide will act as greenhouse gases and trap heat on Earth.

Man-made 'disasters' are more usually referred to as our daily lives. What humans are doing now mostly contribute to global warming. For example, driving a car to work, switching on the air-conditioners at home when you are out, or even throwing recyclable materials into your rubbish chute that leads to the incineration plant contribute to global warming.

Social impacts can be caused by natural and man-made disasters. Natural disasters can cause houses to be damaged, resulting in many casualties and homeless people.

Not forgetting, global warming is posing the largest threat seen so far in the social environment. Global warming causes a rise in the Earth's temperature. This small rise may result in more frequent and stronger natural disasters such as hurricanes. The sea levels will rise due to the polar caps that are melting at the poles. Island nations in the Pacific Ocean and many coastal cities are threatened by this rise of sea levels and they will have to find other places further inland or even in other countries to stay. Crops will be destroyed by the more frequent and stronger natural disasters, resulting in a famine. Summers will get longer while winters will get shorter. Countries or cities than depend on winter sports or such to maintain their economy will suffer a huge blow.

Economically, natural disasters will cost the government a lot of money in rebuilding costs. This will result in a poorer economy as investors may run away from these countries due to either dangers or financial losses.

Again, due to global warming and rising sea levels, low-lying countries such as the Netherlands will have to build more dams to prevent frequent floodings, costing the government a lot. Diseases which spread due to higher temperatures will have to be controlled by the government pumping more money into healthcare research. There are also many other effects that will heavily impact a country's economy.
