When British government decided to abolish Corn Laws, cheap agricultural products were imported to England. It became difficult for the local producers to compete with imports. Many left agricultural activities and migrated to cities and even overseas. This resulted in the growth of global agriculture. Countries like Russia, Eastern Europe, America, Australia increased their food productivity to satisfy British needs and became industrialised.The self sufficient economy abolished and a new global agricultural economy emerged. So, Britain's decision to import food grains served as a boon to global agriculture.
