Maybe use less insecticides and less pesticides when growing plants on farms. Growing more organic food. GMO's were supposed to make food producing plants more drought resistant, more disease and pest resistant while producing more fruits and vegetables than a non GMO plant.

Another way to maintain our species is to build a base on the moon and mine it for ra materials that can be used on Earth in manufacturing.

The famous Astronomer Carl Sagan said "We need to be a two planet species". We need to build a base on Mars. Humans need to colonize it and work towards terraforming it. If a catastrophic event occurs like the one which destroyed the dinosaurs, life for humans can continue. Sagan also said "The reason the dinosaurs became extinct was due to, they didn't have a space program". We not only learn about the solar system and the universe by exploring space, but e learn more about ourselves and hen we may have come from as well as the building blocks of life. I did an internship working on the Mars Phoenix Lander. It was a fun project to be a part of and an important one for exploring the North Pole region of Mars. I hope to see the first humans to land on Mars in my lifetime, just like Neil Armstrong and Buzz Aldrin who landed on the surface of the Moon watched by my parents and millions of others during the previous generation.

It appears to me that there are MORE people today with food allergies than there were in the 1970's and 1980's when I was in school. I never heard of someone being allergic to peanuts or wheat/gluten in the 1970's or 1980's. These allergic reactions could be a result of using more (Genetically modified plants) and /or Genetically Modified Organisms and pesticides in and on our food plants along with using more growth hormones/antibiotics in farm animals that are grown for humans to eat. Humans need to be more health conscious. They need to be more active. Exercise more. Eat more healthy. Eat more organic foods and less processed foods. Start growing more food in their own garden or in a neighborhood garden.

To increase the accessibility of clean, disease free, freshwater for people and animals to drink, use for cooking, use for bathing, irrigating crops, etc si to build more desalination plants along the coasts of the USA and other countries who are experiencing water shortages from either drought, reduced freshwater sources, over population or over use. These plants need to be co-located next to an electricity producing power plant. This will provide the needed power to the desalination plant to process the seawater into purified drinking water. This will also provide the country, region, city etc, with additional electricity to power their society. The average cost of electricity per year to power a desalination plant i $10 million US dollars. The Tampa Florida desalination plant can provide about 25 - 30 million gallons of freshwater per day out of seawater. This water is used by about 2.5 million residents every day plus used by a variety of businesses. This would be an excellent way to get freshwater to many desert and drought stricken areas in the middle east, africa, Australia and in the United States.

It’s increasingly crucial in a world where freshwater resources are progressively strained by population growth, development, droughts, climate change and more. That’s why researchers and companies from the United States to Australia are fine-tuning a centuries-old concept that might be the future of quenching the world’s thirst.
“When it comes to increasing water supplies, you have four options: Increase your amount of reuse, increase storage, conserve it or turn to a new source,” says Tom Pankratz, a desalination consultant and current editor of the weekly trade publication "Water Desalination Report." “And for many places around the world, the only new source is desalination.”
Costly Process
Desalination technology has been around for centuries. In the Middle East, people have long evaporated brackish groundwater or seawater, then condensed the vapor to produce salt-free water for drinking or, in some cases, for agricultural irrigation.
Over time the process has become more sophisticated. Most modern desalination facilities use reverse osmosis, in which water is pumped at high pressure through semipermeable membranes that remove salt and other minerals.
Worldwide about 300 million people get some freshwater from more than 17,000 desalination plants in 150 countries. Middle East countries have dominated that market out of necessity and energy availability, but with threats of freshwater shortages spreading around the world, others are rapidly joining their ranks. Industry capacity is growing about 8 percent per year, according to Randy Truby, comptroller and past president of the International Desalination Association, an industry group, with “bursts of activity” in places such as Australia and Singapore.
In the United States, a $1 billion plant is being built in Carlsbad, California, to provide about seven percent of the drinking water needs for the San Diego region. When it goes online in late 2015 it will be the biggest in North America, with a 50-million-gallon-per-day capacity. And California currently has about 16 desalination plant proposals in the works.
But desalination is expensive. A thousand gallons of freshwater from a desalination plant costs the average US consumer $2.50 to $5, Pankratz says, compared to $2 for conventional freshwater.
It’s also an energy hog: Desalination plants around the world consume more than 200 million kilowatt-hours each day, with energy costs an estimated 55 percent of plants’ total operation and maintenance costs. It takes most reverse osmosis plants about three to 10 kilowatt-hours of energy to produce one cubic meter of freshwater from seawater. Traditional drinking water treatment plants typically use well under 1 kWh per cubic meter.
And it can cause environmental problems, from displacing ocean-dwelling creatures to adversely altering the salt concentrations around them.
Research into a suite of seawater desalination improvements is underway to make the process cheaper and more environmentally friendly — including reducing dependence on fossil fuel–derived energy, which perpetuates the vicious cycle by contributing to climate change that contributes to freshwater shortages in the first place.
Membrane Upgrade
Most experts say that reverse osmosis is as efficient as it’s going to get. But some researchers are trying to squeeze more by improving the membranes used to separate salt from water.
Membranes currently used for desalination are mainly thin polyamide films rolled into a hollow tube through which the water wicks. One way to save energy is to increase the diameter of the membranes, which is directly correlated with how much freshwater they can make. Companies are increasingly moving from eight-inch to 16-inch diameter membranes, which have four times the active area.
“You can produce more water while reducing the footprint for the equipment,” says Harold Fravel Jr., executive director of the American Membrane Technology Association, an organization that advances the use of water purification systems.
A lot of membrane research is focused on nanomaterials — materials about 100,000 times smaller than the diameter of a human hair. MIT researchers reported in 2012 that a membrane made of a one-atom-thick sheet of carbon atoms called graphene could work just as well and requires less pressure to pump water through than polyamide, which is about a thousand times thicker. Less pressure means less energy to operate the system, and, therefore, lower energy bills.
Graphene is not only durable and incredibly thin, but, unlike polyamide, it’s not sensitive to water treatment compounds such as chlorine. In 2013, Lockheed Martin patented the Perforene membrane, which is one atom thick with holes small enough to trap salt and other minerals but that allow water to pass.
Another popular nanomaterial solution is carbon nanotubes, says Philip Davies, an Aston University researcher who specializes in energy efficient systems for water treatment. Carbon nanotubes are attractive for the same reasons as graphene — strong, durable material packed in a tiny package — and can absorb more than 400 percent of their weight in salt.
Membranes have to be swapped out, so carbon nanotubes’ durability and high absorption rate could reduce replacement frequency, saving time and money.
