Kudzu is a climbing, woody, perennial vine that originates from Japan. From 1935 to 1950, farmers in the southeastern United States were encouraged to plant kudzu to help reduce soil erosion. Without natural enemies, this vine began to grow out of control. In 1953, it was identified as a pest weed, and efforts to eradicate this invader continue to this day. Today, kudzu inhabits about 30,000 km2 of the southeastern United States. From 1935 to the present, what is the spread of this pest in square kilometers per year?
The spread of the pest in square kilometers per year from 1935 to the present.
The weed kudzu started growing in 1935 and spread about 30,000 kilometers by current year, 2019. Hence, from 2019 to 1935, it is about 84 years...
