Solution

BT corn and BT eggplants are genetically modified to produce a toxin (Bacillus thuringiensis) that is harmful to certain insects but harmless to humans. This toxin effectively kills many of the pests that would otherwise damage these crops.

Here's how it works:

  1. Reduction in Insecticide Use: Since BT corn and BT eggplants have their own built-in defense mechanism against pests, farmers don't need to use as much chemical insecticides on their crops. This not only reduces the cost of farming but also lessens the environmental impact of agriculture.

  2. Improvement in Farmer Health: By reducing the need for chemical insecticides, BT crops also help improve farmer health. Farmers who use chemical insecticides are often exposed to these potentially harmful substances. With BT crops, this exposure is significantly reduced.

  3. Increase in Crop Yield: BT crops are more resistant to pests, which means fewer crops are lost to insect damage. This leads to higher crop yields. Additionally, because the plants are healthier and less stressed by insect damage, they may also produce more robust produce.

So, the correct answer to your question is: "It produces a plant that kills insects but is harmless to humans".
