Farmers believe that every day should be for the environment, because we depend on the environment to produce the food the world demands. We need good plants, good soil, and good weather. Without a good environment, we’re helpless.

That’s why we must take advantage of opportunities such as World Environment Day. Think of it as a second Earth Day. Each June 5, the United Nations sponsors WED. This year’s theme is “Think.Eat.Save.” Organizers have a specific request: “reduce your footprint.”

Here on my farm in Uruguay, that’s what we do all year round, thanks to advances in technology.

My family farms almost 6,000 hectares (roughly 15,000 acres) near the town of Mercedes, in Soriano. Our most important crops are soybeans, but we also grow corn, sorghum, wheat, barley, canola, oats, and grass seeds. The weather is variable but we never see snow, which allows us to plant for 12 months.

We started growing GM crops 16 years ago. It became obvious immediately that they’re excellent for conservation.

As the website for WED points out, agriculture accounts for 80 percent of the world’s deforestation. This is the result of pressure to convert wilderness into farmland, to keep pace with a booming global population. To protect what remains, we must produce more food on less land—and that’s exactly what biotechnology lets us do.

The first year we planted GM soybeans on our farm, in 1997, we tried it on 30 hectares. The results were amazing. Within two years, we had converted entirely to GM soybeans. When biotechnology came to corn in 2004, we quickly switched to it as well. Genetic enhancement drove our yields upward because these excellent crops are so good at fighting weeds and pests.

Our experience shows that science can help us produce more with less—the very definition of sustainable agriculture.

There are other benefits as well. We’re now able to do a much better job of maintaining natural pastures for a combined crop-cattle operation. This helps us preserve biodiversity.

Best of all, however, is our no-till farming system. Soil erosion is a huge challenge for farmers around the planet, but our soil is actually improving each year. Our crops pump carbon into the soil, and we can keep it there because we no longer need to fight weeds by tilling the soil after harvesting. At the end of the growing season, we simply leave the straw on top of the soil.

A friend of mine, Carlos Crovetto of Chile, puts it well: “Grains are for the people, straw and residues are for the soil.”

GM crops make this possible.

Here’s another statistic from the WED website: Agriculture is responsible for 30 percent of the world’s greenhouse gas emissions.
