The most valuable tool we have to meet the world’s growing energy demand while reducing greenhouse gas production could be figuring out how to use energy more efficiently. Investing in energy efficiency can also save money, reduce pollution, encourage development and create new jobs. Yet, efficiency is often passed by in favor of more expensive energy solutions.

Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human populations increase and shift away from traditional diets, demand for food is expected to increase dramatically — and genes from wild relatives could play a huge role in ensuring we have the raw materials we need to sustainably intensify crop production for future global food security. But will they be available?
