Question 1

The development of agriculture has had a positive effect on humans as it helped us increase our population size and develop complex societies. Has the development of agriculture had an equally positive effect on other species in our environment?

Accepted Answer

A)  Yes, because they were also able to increase in population size and in complexity of society. 
B)  Yes, because all other species eat the same foods we do and benefited from its presence in mass quantities. 
C)  No, because any species that live near humans suffer a decrease in population size. 
D)  No, because as humans devoted large areas to a single crop, environmental complexity was reduced.
