Every year,more people face poverty and hunger and more of the earth's resources are ruined.The problems are enormous,but many experts believe that the situation is not hopeless.The solution will require big changes in how we think about agriculture,food,and our planet.
first of all,farmers everywhere need to develop methods that are less destructive to the environment.
The change from single crop farming to a mixed crop system would be one important step.
The planting of various crops improves the soil and helps prevent erosion.
Erosion could further be prevented by planting trees to protect the fields from the wind.
Another way farmers could improve their soil is to stop deep plowing.
In fact,only a light plowing is necessary,or sometimes no plowing at all.
