  In the era of hunters and gatherers, people always hunted to store food. Not long after this era, neolithic appeared, it's the time that people started to farm and raised animals that make themselves alive. There're good effects of agriculture but there's also bad effects in nowadays, not only affected the environment but also affected the food's quality.

(Agrarian era, people farming and keeping animals, those are the resources of their food production)

What good things did agriculture bring for us in the agrarian era?

—People started to have more choices of food, not only meat but also crops and other different

kinds of food.

—It kinda developed the civilization 

—People started to have the ideas that create new techniques

—People had more free time 

—They  were able to support many people and they didn't have to worry about the food supply.

One example is Egypt, it was a really successful civilization.

But besides those good things, with the development of civilization and cities,  however, nowadays  things started to change,  agriculture no longer only brings good aspects but also negative things,  for example Genetically modified food, they are not natural, and they have bad effects to the environment, bad for some kinds of insects. One specific example about agriculture brings bad effects is in China, the farmers have less devotion to farming and lands, they  feel like is hard to do farming and don't want to take this kind of  difficult job. And agriculture can't take the nature disasters.

Last but not least, for thousand of years , agriculture does bring us a lot of beneficial things that make our lives more comfortable and easy, and it's also the basic of our life, but on the other hand, it has negative effects, through the second article I can kinda learn that agriculture has the effect on Carbon Dioxide Emissions which increases the CO2 in the atmosphere. And brings some waterborne Zoonotic Diseases.

For the conclusion, through the information that I've read , I learnt about how agriculture brings both positive and negative effects to human beings and how they develop in human history.
