The pesticides, herbicides, and fungicides have all helped in the protection of the pants and destruction of pests, which further led to an increase in production, but their usage has also led to pollution of the soil and water. Unfortunately, the usage of chamicals has led to increased health risks, and significantly lowering the organic production which was dominating before.

Shifts in the Earth's crust cause tectonic plates to shift along the fault lines. This causes extreme friction & energy which is released in waves, causing an earthquake.
Answer:
Because the high pressure areas are associated with cold air masses which push away out of polar regions during the winter when there is less sun to warm neighbouring regions.
