How have the availability of natural resources, occurrence of natural hazards, and changes in climate influenced human activity over time?

Natural resources have been greatly depleted over the years. Although we still have plenty of resources left, they are decreasing at a very high rate. This is due to the need for factories to produce our modern world goods, more humans, more need for production. With this increase in production, hazardous bi-products are harder to clean up. As you can see, this all ties in with climate change as well. With the increase of population growth, more factories are being created that produce toxic gas blocking the exit for heat, trapping it on earth. Global warming plays a huge part in how the weather is affected.
