Answer to Question 1
Although most humans in the developed world believe that living a sustainable life will require great sacrifice, simple lifestyle changes that do not lead to major decreases in our standard of living can lead to more sustainable living. When humans examine their over-use of such things as water, energy, land, and mineral resources, and keep the future in mind rather than looking to short-term gains in living standard and profits, then the negative impact of humans on the Earth will be greatly reduced. Sustainable options for living are possible with planning and when given precedence over profit. If and when our people and particularly our leaders begin to refocus our priorities and become more sustainable, then we will be able to live more in balance with the Earth while maintaining a modern civilization. The sooner this shift in attitude happens, the more likely that goal will be possible.
Answer to Question 2
Hazard is anything that can cause (1) injury, disease, or death to humans, (2) damage to personal or public property, or (3) deterioration or destruction of the environmental components. The existence of a hazard does not mean that undesirable consequences inevitably follow. Instead, we speak of the connection between a hazard and something happening because of that hazard as a risk, defined here as the probability of suffering injury, disease, death, or some other loss as a result of exposure to the hazard. Some people are more prone to being exposed to hazards because of the environment and cultural situation that they find themselves in. This is vulnerability. Risk = Hazard x Vulnerability.
