The biodiversity emergency: what can we all do?

There is a biodiversity crisis. The repercussions of species and habitat loss are everywhere: Animals (giant pandas or bees), and places (coral reefs), are experiencing negative human-related impacts. This means more than just loss of physical beauty; all habitats and species are interconnected, so a loss of something as seemingly small as a bee population will reduce pollination of plants that we eat. There is hope of recovery, but it begins by motivating people to help. As the world is becoming more urbanized and disconnected from nature, where does motivation for environmental conservation and stewardship come from?

Pave Paradise and Put up a …Desert?

As the song goes, “you don’t know what you’ve got ‘til it’s gone; they paved paradise, and put up a parking lot.” (Joni Mitchell). Now, what if, instead of a parking lot, they paved a mega-city?

The global buzz: A call to restore insect biodiversity

Insects are in decline worldwide. Without a rethinking of current agricultural practices and a bucking of trends in urbanization, biodiversity of insects is threatened globally. Insects are the structural and functional base – the linchpin – of all ecosystems. We are part of those ecosystems. Unlike the vastness of climate change and its many aspects, the solutions to the problem of insect declines are readily available. With proper perspective, appreciation, and respect for the roles insects play in ecosystem integrity, human health, and economic markets, we can reverse course.

Community and home gardens are hotspots for pollinators in cities

Pollinators, such as bees, are important parts of the environment since they are required for plant success and fruit production by humans and animals alike. However, populations of pollinators have been declining worldwide due to a number of issues, including widespread pesticide use and loss of habitats. A recent study conducted by researchers in the UK and their colleagues examined pollinator use of urban areas, comparing community gardens, home gardens, cemeteries, and other spaces. The researchers show that the abundance and diversity of many pollinator groups was highest in community and home gardens, and suggest that urban planners should increase these spaces to boost pollinator populations.
