The USA recently held National Agriculture Day.

A key concern expressed by many of those participating this year was the need for greater investments in the very foundation of American agriculture: the research, development and extension services required to maintain the high productivity and environmental sustainability of American farmers and ranchers and to provide sufficient nutritious food, fibre and biofuel for a growing world.

Challenges include the multiyear drought in California and many Western states; threats from disease affecting livestock, poultry and citrus crops; nutrition and obesity-related health issues; and a troubling shortage of young farmers and veterinarians choosing agriculture as a profession.

But we cannot afford to fail – the global population will rise by 2.3 billion by 2050.  We have to feed all those people!
