One word that sums up the problem: Agriculture.
Our food and agriculture system is particularly broken, but we can’t simply wait for the government to fix it. As with clean energy, there are many opportunities for private enterprise to stimulate progress while making a profit. Some of the short-term opportunities in food might be to leverage consumer awareness and build a brand that stands for environmental consciousness, while aligning for longer-term regulatory changes to level the playing field.
A great piece by Ari Partovi. Anyone who helped make Dropbox is okay in my book. He thought to invest in a company that puts greenhouses in the roofs of supermarkets.
