The economy is a fundamental axis of a country. Without it, you can't buy anything, neither sell. Also you won't have food to eat. So the economy, at international scale, is more important. Countries need to do commerce to sell and buy things that they not have. But... What would happen if the global economy is affected? Maybe the fist affected countries would be the poorest ones. They generally need money from other countries to survive and to pay to the factory employees. If something would be able to "destroy" the global economy that would be the climate change.
Global growth top
Yes, another concept with "the global" word, but is very important. The global growth indicates if the world is economically good, bad. In order to measure it (there is no only one form to measure it) stock-market of values of different places from the world can be studied, like Wall Street , Tokyo , London and Taiwan . If all of them are growing, it assumes that we are well. When all the stock markets fall of a day for another one, is called "black day". Let's imagine the case of an increase in the level of the sea in three meters. One of the first places in flooding is the coastal cities, that is, the ports. On them great part of the world-wide commerce depends, like the transport of electronic and food. Diverse islands of the Caribbean and the zone of Indonesia would get flood, as it happened to the Tsunami of the year 2004 (although this did not have any relation with the climatic change). The president of the World Bank said in an interview that the world-wide growth would be affected in one fifth (1/5) if a drastic action against the climatic change were not taken.
At the moment, the main source of foods at world-wide level is agriculture. The flour, an essential product for any kitchen, is obtained there. For that reason if the production of the countries affect to the agriculturists, the provision of food at world-wide level could fall, elevating the prices and directly affecting the poor people. Indeed, the climatic change and, specifically, the global warming, affects negatively to agriculture, because the temperatures are more extreme, and in some cases there is less rain. But in other cases, like in Chile , a rain in the summer can affect all the wine production, since it tends to generate fungi. The climate now is more unpredictable than 40 years ago. That causes that an agriculturist does not know if they must fumigate its plants. If they have to, the prices of its product increase.
One of the more affected industries is the one of the insurances. Following the data of a study, between the 35 and 40% of the losses by climatic causes they are related to the climatic change. According to a report of the Association of British Insurers, if somebody limits the CO2 emissions would be possible to be gotten to reduce in an 80% the hurricanes that arrive at the coast in the year 2080 to the tropic.
Throughout history the cities located in the coast always are affected by the floods and other natural disasters. For that reason the climatic change can have great relevance at the time of investing in coastal infrastructures, like docks, to stop to the floods that more and more will be followed. These docks generally are very expensive, to which there is to add a cost to him of repairing, among others. It would be very difficult to put in each coastal city that is possible a catastrophe, in addition to the enormous price. For example Vienna needs docks now, and the studies indicate that to surround a city of that size it is a multimillionaire cost. However all the countries do not have to construct docks to contain to the water, only those that have their cities are under the sea level, like Netherlands or Bangladesh . The IPCC notices that in 2050 there will be than 150 million people sheltered in other countries because of floods. For Tuvalu , an archipelago of islands in the Pacific is nonviable to construct to defenses against the floods, reason why it has a deal with New Zealand in case of this disaster to evacuate its population.
Water shortage top
In Peru the glacier melting has caused that its potable water reserve has diminished in a 25%. The illegal sweepings garbage dumps can contaminate the underground water that exist under them. As the poorest people live near these rubbish dumps, they drink this water, which increases their percentage of diseases.
The high temperatures will also demand more water, for the cooling of buildings of all type and also for the human consumption and in the cases of agriculture, for the animals. In some places, like Sahel , rain to gotten to diminish in a 25%.
The countries that depend on mountains to obtain their water, like Chile, will have to look for ways to get it, since the climates will also change in the mountains, warming up them or cooling them. Both with different consequences but with he himself effect: smaller amount of water for the population.
Costs of reducing the CO2 Emission top
If the CO2 is one of the main causes of the climatic change, then. why not to reduce its emissions? This sounds easy to say but actually it has highest costs for the industry. First which is need to do is to reduce the fossil fuel consumption, like Petroleum. For this we needed machines that consume less and than they render more, that is, than they are energetic efficient. It is needed to repair hundreds of machines that emit CO2, or simply to replace them by some hybrid ones. This finally will pay its high cost, spending less energy.
If to low the climatic change is expensive, more expensive is to do anything, and to wait for their effects come, which would be disastrous for the economy. Floods, bankruptcies, lack of food and so many other things that will happen. And some effects can be seen today. The effects in the world-wide economy would be enormous, but more important they are the human lives, the most affected, without leaving of side to the animals and the plants, which are only victims of the climatic change. The human being will be victim if he does not do something soon.
