Answer:
During eruption, volcanoes emit a mixture of gases and particles in the air. Ash particles and gases such as sulfur dioxide have a cooling effect because they reflect the sunlight far away from the earth. A gas like carbon dioxide has a greenhouse effect and heats the earth. Volcanic eruptions also throw out melt walls that form new walls on the surface of the earth and change its configuration, and together with the ash particles change the mineral composition of the soil. Particles of volcanic eruption affect the composition and quality of water, which, through evaporation, deliver this chemical composition with it and affect the atmosphere, which again through the precipitation affects the soil. But also those influences affecting the atmosphere also affect climate change. The changed mineral structure of the soil, together with such altered chemical composition of water and precipitation affects the plants. Animals feeding such plants inhale such air, they also feel these effects, and this reflects on the quality of milk, meat, food in general, which naturally affects people. The composition of the soil changes over time, which affects the amount of yield, maybe even the change in cultivated crops may occur.

Answer:
The nation faced serious economic and political problems. The country needed to build a new system of roads. They wanted to overthrow the president of the confederacy.
Richard went gallently off to war, leaving his brother, an incompetent ruler, in his stead. John was so bad that the Magna Carter was signed on his watch. That was helpful because it took some of the monarch's power away. It didn't help everyone since it only gave rights to some of the nobility, but it was a start.
That was one effect of the crusades in England. Richard the Lionhearted likely would have had the same difficulties that John had to cope with. Richard was not a great politician (he put rebellions down with force), but he was a very gifted military technician. John faced the problem of having not much of an army to resist those wanting him to sign the Magna Carta. That should get you started.
