Scientists argued that GMOs can help in many ways, including developing crop varieties that are resistant to diseases, drought, predators or pests, a move that they say will lead to food security in Africa. But not everyone agrees … Read more … …
As our global population continues to grow and the climate becomes hotter and drier and resources become scarcer…. we need both food and fresh water to survive, but growing food demands significant fresh water as well. Our efforts to ensure both food security and ample fresh water supplies are intertwined, …

Global warming and changes in the amount – and location – of water, are key factors in the need to continue crop breeding programs. In addition, there are many diseases that affect crop yield and quality. We need to continue breeding new disease resistant crop varieties to ensure a healthy, …
On a bleak, brown hill here, David Ellis examines a test plot of potato plants and shakes his head. “They’re dead, dead, dead,” he says. Pests and lack of rain have laid waste to all 17 varieties that researchers had planted.
It is a worrying sign for Ellis, the now-retired director …
Politicians and policymakers have failed to grasp the gravity of the environmental crisis facing the Earth, a report claims.
The think-tank IPPR says human impacts have reached a critical stage and threaten to destabilise society and the global economy.
