Don’t know the long term effects of GM crops on human health.

Detailed explanation-1: -These GM plants have increased efficiency of mineral usage hence prevents early exhaustion of fertility of soil. They have enhanced nutritional content. For example, golden rice which has been engineered to contain the gene encoding precursor of vitamin A.
Detailed explanation-2: -Disease-and drought-resistant plants that require fewer environmental resources (such as water and fertilizer) Less use of pesticides. Increased supply of food with reduced cost and longer shelf life. Faster growing plants and animals.
Detailed explanation-3: -They concluded that GM crops allowed an increase in yield of 6 percent to 25 percent, depending on the country, with the additional benefit of reducing mycotoxin levels by one-third. These toxins contributed to major economic losses and cause serious health problems.
Detailed explanation-4: -Benefits include economic and environmental growth, crop durability, food security, and improved nutritional value. The genetic engineering executed in the modified organisms causes the organism to ripen faster allowing crops to grow and multiply faster.
Detailed explanation-5: -GMO crops are more resistant to pests, weeds, and other threats. That means farmers have less of a need to apply pesticides or herbicides to their crops, which saves them money and potentially increases the health benefits of the food being grown.
