Transport of invasive species

The high costs of invasive species

“Species introduced to new regions through human activities are termed alien species. Invasive alien species represent a subset of alien species – animals, plants, and other organisms – known to have established and spread with negative impacts on biodiversity, local ecosystems and species. Some of the most problematic invasive alien species arrive through multiple introduction pathways and repeated introduction. Invasive alien species are recognized as…

Dust storms in the United States: a mixture of corporate agriculture and climate change

The Great Plains and Midwest regions of the Unted States are seeing more and larger dust storms and higher levels of dust in the atmosphere. The increase has corresponded to an intensification of corporate agricultural practices in these regions–an example is the plowing of grasslands and marginal agricultural land in order to grow more corn for the production of biofuels. Even modest corn production on…

Climate change and agriculture: damage to crops

Our changing climate is impacting agriculture today and will continue for decades to come. No place on Earth is immune to this; the major growing areas of the world are being affected. Additional impacts brought on by war, supply chain issues, resource shortages, and more just add to the impacts and the consequences. And beyond smaller harvests, crops grown in high carbon dioxide (CO2) conditions…

Food waste: beyond good ideas, what will people actually do?

On an international scale, food waste is a big problem. “The largest contribution to food waste is from the consumption stage, where household food waste represents the largest share.” In a time of growing food insecurity even in so-called richer countries–due to war, the effects of climate change on agriculture, supply chain problems, and more–wasting a large percentage of the food that is produced magnifies…

Agriculture and climate change: foods for the future

Climate change is impacting agriculture around the world. The greater frequency of weather extremes including heatwaves, drought, and it’s opposite, torrential rainfall and flooding (and their consequences) are impacting crop yields and sometimes destroying harvests. The world’s population is growing; how do we feed more people when corporate agricultural practices and a changing climate are impacting the amount of food being grown and produced? One…

Bacteriophages: basic science and applications

“We urgently need an alternative method to fight bacterial infection. One promising method for killing bacteria is to use bacteriophages: viruses that infect and kill bacteria … As a type of virus, phages cannot live and reproduce alone. Viruses need to invade a host cell, consume the host’s nutrients to make more copies of themselves, and lastly get out of the host cell – often by…
