BP3: Wider variety of food

Thesis

farmers in different ways, even financially,
increases the amount of food and creates a wider
variety of food.

Food supply


Most grown foods are
genetically altered in
some way


Climate tolerance


Pets repellants


Physical changes

GM and Farmers


Saves them money.


Gain profit


Higher yield=greater profit



Larger amounts of produce are surviving.


GM seeds



Natural pesticides.



GM seeds


Toleration to
environment


Produce natural
pesticides


Inherit and pass on
modified genes


Physical traits

No need for sprays


Farmers no longer need to spray crops.


Can be toxic


Harmful to environment


Consumers do not want to eat food that has been
treated with pesticides because of potential
health hazards.

Replenishes food supply


Greater yield


Larger produce


More surviving


GM solves spoiling issue

Greater selection


GM foods increased the variety and preference


Seedless watermelon


Consumer convenience


Consumer preference

Consumer convenience


Japanese farmers have forced
their watermelons to grow in a
square shape by inserting the
melons in a square, tempered
