However, there is a difference between Dragons Teeth (cross genus DNA manipulation) and moving genes from one variety in a species to another (genetic hybridization). Dragons Teeth is an old farming term for plants that do not reproduce normally, because they are genetically faulty. Natural plant seeds have "Hybrid hardiness", but current commercial GMOs are monospecies and pests are adapting to that species.
The CRISPR technology discussed in the article could be a boon to agriculture. It produces different varieties of the same species and does not introduce toxins.
So far, most genetically modified seeds produce poisonous plants. Almost all of the non-organic corn produced in the US now produces the BT toxin, derived from bacteria. This toxin is actually in the corn kernels we eat, and is toxic to humans as well as bacteria. This should be identified by a USDA Black Box Warning (as with tobacco).
The other common modification is Roundup resistance. This allows farmers to spray their crops and eliminate weeds which can rob the crop of water and sunshine. However, spraying Roundup onto the entire plant (instead of around the plant) increases the amount of Roundup in the food and increases toxity. New weeds are becoming common that are Roundup resistant, so Monsanto (who manufactures both Roundup and the seeds) is developing seeds that are resistant to both Roundup and another herbicide that Monsanto produces. The safe level of Roundup is still under debate, but the combination of herbicides is much more toxic.
The sad part of Roundup resistant crops is that it is only necessary because farmers are still planting crops in wasteful furrow plowed fields. Using furrow plowed fields wastes a lot of water, causes the loss of topsoil, and moves the crops further apart than necessary (thus wasting farmland). The soil should flat with a slight slope and the ground should be virtually covered. If the ground is covered, the weeds do not have enough sunlight to grow. The space between the main crop plants should be carpeted with a ground-cover plant. Using clover, alfalfa, or other limited height plants helps grow a more plentiful crop and provides fodder that can be sold to ranchers.
The article makes a passing mention of the fact that farmers are not allowed to plant seeds produced from current GMO seeds. Monsanto and other companies have sued farmers whose plants were contaminated with pollen from GMO plants, even though the farmers had not signed any contract with the company and were trying to grow organic crops. This has caused a virtual monopoly in Corn seed. It should be the other way around. Those providing the GMO seeds and those planting those seeds should be responsible for elimination of the contamination of other farmers' crops.
The reason that individual farmers (rather than agribusinesses) reject GMOs is that they lack hybrid hardiness, the farmers are required to pay for new seed every growing season, and they have good historic reasons to mistrust the chemical companies which produce GMO seed.
States currently in multi-year droughts would require multi-year heavy rains to refill the reservoirs. All of the states West of the Rockies (except Hawaii) are currently in a drought. In California, where there have been 4 drought years in a row, the probability of a drought year next year is over 75%.
Severe water rationing may become necessary. This could include restricting tap water to certain hours of the day (like the rolling electrical blackouts a few years ago), reducing the pressure in water mains, elimination of all potable water for landscaping, and closing of businesses that do not recycle their water.
In California, severe water rationing has already hit agriculture. Farmers are not allowed to use water from rivers and reservoirs, so farmers are pumping from local wells. Some of the irrigation water sinks back into the aquifer, so it will be available for wells in the future. However, another drought year would empty many of the wells and severely reduce the US production of vegetables and cotton.
Starting immediately, all penalties for over-use of water should be used to increase the amount of water available.
To solve this long term problem, one needs a plan with a time-line and objectives. This proposal was submitted to the California State Resources Board and California governor several months ago.
Summer 2015, all processed sewage should be recycled. Water not used locally should be pumped to agricultural areas or used to recharge aquifers (pumped through plants and gravel into ground water). The cost is low, requiring that gravel-bottomed ponds (with recharge wells) be placed in overflow basins, and pumps and pipes to get the water there. Using the gravel, ponds, and plants ("Bio-filters") helps to purify the water before it enters the aquifer.
Spring 2016, excess recycled water should be made available for agricultural use. Possibly by pumping recycled water from cities for aquifer recharging in the Sacramento area. Most of this water would be pumped up-stream, so a large pipeline and pumps should be installed. Because most of this pipe would be installed next to the state's aqueducts, there would be no additional land costs and an emergency waiver of environmental impact reports would probably be approved. Water could be made available for environmental improvements to Owens Lake and the San Francisco Delta.
By the 2016-2017 rain season, the state's waste water processing plants should be expanded to handle the water from storm drains (rivers and washes). San Francisco and some other cities already do this. Untreated water from storm drains is a health hazard. This water could be added to the recycled water.
A long term improvement that might require a bond measure and federal funding is desalination of salt water (ocean water and agricultural runoff). Within 30 years, California should acquire 50% of its fresh water needs by desalination. A target of 10% by 2025 is reasonable.
