Local weather modify and agriculture are interrelated on a world scale. Weather alter has an effect on agriculture by changes in regular temperatures, rainfall, and climate extremes (like storms and warmth waves); variations in pests and health conditions; alterations in atmospheric carbon dioxide and ground-level ozone concentrations; adjustments from the nutritional good quality of some foods;[174] and alterations in sea level.
For most of our existence, humans were hunter-gatherers. Because of this people today lived a nomadic Way of life, relocating While using the seasons to Stick to the food items source.
