What is human trafficking about? need this asap!

Human Trafficking is the act of recruiting or abducting people (usually children and teens) and doing...let's just say bad things to them. Some things could involve sexual acts, forcing them into labor, and even torturing them (like removing their organs or just doing it for fun). 

People usually do this to gain money from it, which gets them a lot. In easier words, Human Trafficking is illegal and slavery. 

Humans have survived and thrived in mexico city by using technology to create greater access to land. when the spanish conquered the aztec capital, tenochtitlan, in the 16th century, they built mexico city by draining the lakes and filling in the lake water to create more arable land for agriculture. this technique of land reclamation has continued to be fundamental to human civilization in mexico city.
