From the Vedic scriptures we learn that there are different cosmic seasons. The present one is called the age of Kali, or the age of quarrel and hypocrisy. In the age of Kali the sinful activities in human society increase. According to His Divine Grace A. C. Bhaktivedanta Swami Prabhupada, the founder-achayra of The International Society for Krishna Consciousness, the two gravest of these sins are abortion and animal slaughter.
