Dictators usually suppress human rights. Gross abuses occurred in Nazi Germany when Adolf Hitler ordered the mass extermination of millions including the disabled, homosexuals, and Jews. In 1975, thirty-five countries met in Helsinki and pledged to honor human rights. This is known as the Helsinki Agreement. Humans have transformed the environment and adjusted to it, creating many different places on Earth.
Humans affect the environment and the environment affects humans.
In order to understand our world it is vital to understand not only its people but also the environments which sustain them. Most contemporary human-induced environmental changes have not been planned or intended. Many of the effects humans have on the environment are not anticipated. Some are not even felt in the places in which they originate. Rather, they appear in other locations, often places that are environmentally vulnerable.
