I recently found a website that, though not gardening specific, is a great resource for anyone who is following the global environmental issues of the day. You can get a feel about the challenges of the global shortage of water, what is happening in regard to climate and energy around the world as well as what is happening in agriculture, food and sustainability. However, it goes further and explores the solutions to these growing challenges, which is great!
There is also a wonderful community of bloggers that are both well versed in the issues and fun to read. Planet 2025 is well thought out giving perspectives and an actionable plan for individuals as well as small and large businesses. This is good news for those who believe in being good stewards whether that be in the backyard or in the world.
