Echinopsis pachanoi
The San Pedro cactus is very easy to grow in most areas. Because it grows naturally in the Peruvian Andes Mountains at high altitude and with high rainfall, it can withstand temperatures far below that of many other cacti. It requires fertile, free-draining soil. They average half a meter per year of new growth. They are susceptible to fungal diseases if over-watered, but are not nearly as sensitive as many other cacti, especially in warm weather. They can be sunburned and display a yellowing chlorotic reaction to overexposure to sunlight.
Decriminalization of non-medical cannabis in the United States
Ecosystem: A single mature marijuana plant can consume 23 liters of water a day, compared to 13 liters for a grape plant. Historically, many outdoor cultivators have used illegal river and lake diversions to irrigate crops. These diversions have led to dewatering of streams and rivers which is well documented in areas of Northern California. As with any other agricultural crop, increase in demand leads to increased clear cutting of forests which can increase erosion, habitat destruction, and river diversion. Legalization and subsequent regulation could mitigate such issues.
