2. What are Bt Crops?
• Bt crops are transgenic crops that are genetically
engineered from the DNA of bacterium Bacillus
thuringiensis.”
• Bt Crops are transgenic crops that produce the
same toxin as the bacterium Bacillus
thuringiensis in the plant cell, thereby, protecting
the crops from pests. The bacterium secretes
specific proteins known as “cry proteins” that are
toxic to insects. A few of the Bt crops include
cotton, brinjal, corn, etc.
3. Bacillus thuringiensis
• Bacillus thuringiensis is a gram-positive, spore-forming bacteria
which is mainly found in the soil. As stated above, it produces
proteins that are toxic to insects. Organic farmers use this bacterium
in a solution and spray it on the plants to protect them from pests.
• The practice of using Bacillus thuringiensis began in the year 1996
with small quantities of genes from the bacterium. This facilitated the
production of cry proteins in plant cells that helped to kill pests. Pests
like European and southwestern corn borer, tobacco and cotton
budworm, pink bollworm and Colorado potato beetle largely
destroyed the crop yields. Bacillus thuringiensis protected the crops
against such pests.Give a brief overview of what you’ll cover in your
presentation.
4. Advantages of Bt Crops
Following are the major advantages of Bt crops:
• It helps in improving the crop yield, thereby, raising the
farmer’s income. This results in increased farm production.
• They help in controlling soil pollution as the use of synthetic
pesticides is reduced.
• Bt crops help in protecting beneficial insects.
• It can easily feed an increasing population due to increased
yields in a short time.
• It leads to the production of disease-free crops owing to the
reduction of pesticides.
• It leads to more productivity in a small area of land.p of

5. Disadvantages of Bt Crops
Bt crops have a few disadvantages as well:
• Bt crops are costlier than naturally grown crops.
• It can disrupt the natural process of gene flow.
• The pests might become resistant to the toxins produced
by these crops and the crop production might decline.ke

6. Interesting facts
List some interesting facts about Asian Pacific Heritage Month.
Here are a few examples:
• In 1978, President Jimmy Carter signed a resolution designating
May as Asian/Pacific Heritage Week.
• May was chosen to commemorate the immigration of the first
Japanese to the United States on May 7, 1843, and to mark the
anniversary of the completion of the transcontinental railroad on
May 10, 1869.
• In 1992, the official designation of May as Asian-Pacific American
Heritage Month was signed into law.
