After half a century as a student of biology, geology, ecology and health, today I have information that overshadows everything I had learned.

Easy to find on the Internet, ecologist Allan Savory, in a 22-minute TED Talks video, gives an earth-saving answer to desertification, climate change and the future of agriculture. In short, the answer is — animals!

How often the experts are wrong, how damaging the consequences, and how seldom does a scientist see through it all and make corrections! — Ira Edwards, Medford

I was appalled, and find it reprehensible that the MT published the editorial from the Chicago Tribune on April 2 regarding the Keystone XL pipeline.

This is purely a boondoggle project to increase profits for the oil companies (as if they don't make enough and receive subsidies as well) at the risk of "dirty oil" spills, especially where the pipeline will bisect the country. The line will pass over the biggest aquifer that supplies the midwest with clean water — have you people read about the spill in Arkansas and the environmental disaster occurring there? This "dirty oil" will be refined in Texas, but is for export and not for domestic consumption — how does that relieve our energy problem and how much more pollution and greenhouse gases will it produce in the refining process?

How myopic can the Chicago Tribune be to endorse this project that will create more profits for "big oil" and provide another coup for corporate welfare? — Yale Sacks, Central Point

In February, "Forward on Climate," a national day of climate action, was celebrated locally by "The Rogue Thing: Bringing Climate Concerns Home."

Sponsored by SOCAN (the Southern Oregon Climate Action Network), the Medford event saw hundreds of local residents produce over 1,300 house-shaped tiles depicting what is important to them as residents of the valley or what is threatened by climate change. These became scales of a huge salmon in the Porters restaurant parking lot. This earned the area a national reputation for climate change creativity. This was our regional first step.

The theme of Rogue Valley's Earth Day Celebration (11 a.m. to 4 p.m. Saturday, April 20 at ScienceWorks, Ashland) is "Taking the Next Step." When hurricane Sandy barreled ashore, it followed two years of droughts, wildfires and severe weather across the nation that had taken lives and imposed climate related devastation. Imposing costs exceeding $200 billion, the devastation resulted in over 50 percent of our counties being declared disaster areas.

The time to take individual and collective bold action to address climate change is now. During the Earth Day Celebration, SOCAN ( will be challenging visitors to pledge to take bold action. Please join us and rise to the challenge by making your pledge. — Kathy Conway, co-facilitator, Southern Oregon Climate Action Network

Thank you to all Rogue Valley residents who donated both diapers and cash to benefit the Family Nurturing Center during the recent diaper drive held March 16 at Food 4 Less and both Fred Meyer stores.

Your generosity toward some of the neediest children and families in the Rogue Valley is greatly appreciated. Thanks to your support we collected over 18,000 diapers and $1,300, which will be used to purchase additional diapers.

Thank you also to the staff and management at the aforementioned grocery stores who have generously supported this effort for the past four years. — Sue Martin and Jenn Stringer, Jackson County Medical Alliance
