The fate of the Southeast's longleaf pine forests, and the endangered woodpeckers that depend on them, is in jeopardy. Fort Bragg, a station of the US military, is trying to save their local environment.

Colombia’s National Development Plan for cattle ranching seeks to reduce pasture land from 94 million acres to 70 million acres while increasing cattle numbers from 23 million head to 40 million. The program focuses on planting trees on grazing land and the "cut and carry method," whereby farmers grow fields of shrubs and distribute the fresh cuttings to cows in pastures. The result is greater cattle productivity and a more eco-friendly farming system.

The people of Malawi count on wood for cooking, cleaning, and sanitation, which contributes to the country’s ranking as fifth highest in the world for deforestation.

Environmental refugees in Ethiopia flee their country because there are no jobs without healthy land. A group of former refugees have returned to Ethiopia with a business venture in Gergera to improve the land by regreening efforts, foresting, and building water conservation systems. The new businesses demonstrated such positive effects that the region is now on the brink of resettlement due to improved environmental conditions.

After once again being granted rights to their native land, the Martu people are bringing back the bioregenerative technique of small-scale land burning. In the past century, wildfires have ravaged the areas these people call home and has lead to the loss of over 18 species of animal.

Villages along the Irrawaddy River delta in Myanmar have spent years replanting mangroves in at attempt to restore their ecosystem and guard against the negative effects of climate change, but it is a labor intensive and time-consuming process. Now, with the help of specially-designed tree planting drones from startup BioCarbon Engineering, as many as 10,000 trees can be planted in a single day, using technology that not only distributes seeds in special pods, but is able to calculate optimal soil conditions, locations, and species of tree most likely to survive in any given area.

More golf courses are closing than are opening, allowing the rare opportunity to have open space in an urban environment.
