Well some political systems are really well set up so that's why people would want to trade
Rubber bands are different than many other materials because their molecules are actually very long chains, kind of like a tangled pile of spaghetti. These long chains are called polymers, which can behave in surprising ways when you heat or cool them. In this activity you will change the temperature of a rubber band using hot water and ice water, The rubber band actually expands when it gets colder! This seems counterintuitive because most materials expand when they are heated and contract when they get cold. This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.

The farmers from the Midwest in the United States are located in the drainage area of the Mississippi River system. The Mississippi River gets all the water from the region into the Gulf of Mexico where it ends its flow. Because for the farming the farmers are using lot of synthetic fertilizers, pesticides, herbicides, and fungicides, they are managing to pollute the water, be it the surface one, or the ground one. All of that polluted water ends up in the Gulf of Mexico.
The pollution affects the marine life very badly, including the fishes, so their numbers drop significantly because they are dying out from the pollution. That will lead to a situation where the fishermen from the Gulf of Mexico will be left without fish for fishing, thus without profit and without an important food source.
