Prehistoric farmers have been selecting the most productive plants and seeds from their domesticated crops for up to 10,000 years." [1]
GMOs are used to create more plentiful crop harvests, more desirable color/texture/taste, and to resist viruses, pests, or pesticides.]]> 2019-03-07 19:07:11 UTC https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339040946 20birchlera https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339044555 2019-03-07 19:14:10 UTC https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339044555 20birchlera https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339044687 GMOs are created by selective breeding, or special methods of inserting desirable genes.
"The art of gene splicing dates from 1972. In that year, Stanley Cohen and Herbert Boyer developed techniques that made it possible to chemically cut and splice strands of DNA at specific places in the sequence. Boyer used an enzyme to cut the code for a specific protein and attach it to other DNA." [1]
"CRISPR-Cas9 was adapted from a naturally occurring genome editing system in bacteria. The bacteria capture snippets of DNA from invading viruses and use them to create DNA segments known as CRISPR arrays. The CRISPR arrays allow the bacteria to "remember" the viruses (or closely related ones). If the viruses attack again, the bacteria produce RNA segments from the CRISPR arrays to target the viruses' DNA. The bacteria then use Cas9 or a similar enzyme to cut the DNA apart, which disables the virus."

GMOs benefit the economy by being more plentiful and resisting harmful effects. They benefit the environment by allowing farmers to use potentially pest invested environments and conserve space better. They do not benefit the social aspect of sustainability as people are uneducated and there is a general belief they are harmful.]]> 2019-03-07 19:23:23 UTC https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339049541 20birchlera https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339051254 My hypothesis is that general population believes it has no positive affects on the economy.]]> 2019-03-07 19:26:41 UTC https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339051254 20birchlera https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339054970 ‘Where farmers have been given the choice of growing GM crops, the economic benefits realized are clear and amounted to an average of over $100/hectare in 2014’ said Graham Brookes, director of PG Economics, co-author of the report. ‘Two-thirds of these benefits derive from higher yields and extra production, with farmers in developing countries seeing the highest gains. The environment is also benefiting as farmers increasingly adopt conservation tillage practices, build their weed management practices around more benign herbicides and replace insecticide use with insect resistant GM crops" [2]
The use of GMO crops allows for economic growth through plentiful harvests. It was benefiting the environment from less use of pesticides, but as viruses and weeds mutate there is use of stronger or more pesticides which causes waste run off. ]]> 2019-03-07 19:33:11 UTC https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339054970 20birchlera https://padlet.com/20birchlera/zqxu8dfx5wf3/wish/339056376 [1] Wessels: Farming 1970s to today.
