：

bi otechnology

a word

that

’

s been around for about 30 hnology was coined in the shadow of new techniques

that allowed scientists to modify the genetic material in living y

，

that means imitating

biological processes to produce substances that

，

argu ably

，

benefit things like agriculture

，

medicine

and the environment.

benefits

up

the

process

of

breeding

plants

and

animals

with

desired

characteristics;can

be

used

to

introduce

traits

that

a

product

wouldn

t

traditionally

have;can

improve

the

nutritional

value

of

products;and

can

produce

cheaper

and

more

environmentally-friendly

the

supporters

s already being sold in grocery

s called the

principle of substantial there

s no doubt in Bilmer

s a system

that

s working and working well.

Advocacy groups

like the Council of Canadians and Greenpeace

G-M foods could have disastrous consequences to our health.1)To the groups on this side of the

they

argue

the

notion

of

substantial equivalence is not a standard they want a new testing system independent

G-M critics say enough time hasn

argues

Jennifer
