Let’s look at some of the environmental decisions that didn’t quite pan out as people hoped. Even when they have the best intentions, our efforts to protect the planet and make life a bit easier have sometimes caused utter disaster. Here are 10 of these terrible environmental policies. They sounded great on paper yet ended up causing more harm than good.

The Great Toad Invasion
In an attempt to control pests, Australia introduced the cane toad as they thought the toads would eat all the bad bugs. Sadly, these toads didn’t just eat pests—they ate everything else and with no natural predators, they multiplied like crazy. They’re now a bigger problem than the pests they were supposed to eat.
Not So Mighty After All
Farmers once saw DDT as the greatest pesticide around because it’d save their crops & stop insect-borne diseases. But the environmental effect was more serious than they had realized. Birds started laying eggs with shells so thin they’d break under the weight of their mothers. In fact, DDT drove some bird species to extinction and caused widespread destruction.

The Deforestation Fiasco
Encouraging deforestation for farming seemed like a great idea for improving food production. But when huge areas of the Amazon rainforest started disappearing, it began a domino effect of biodiversity loss & habitat destruction. It also contributed significantly to climate change. Was it worth it in the end?
Damming the Rivers, Damning the Consequences
Building massive dams has been great for renewable energy and water resources. But when you mess with rivers, rivers mess back—like with the Three Gorges Dam in China. It has caused ecological problems & displaced millions of people while increasing the risk of landslides.
Too Much of a Good Thing
Overfishing policies seemed like a good way to improve the seafood industry and reduce our reliance on livestock. Soon enough, though, fish stocks started plummeting. It became clear that too much of a good thing wasn’t so great after all and the decision to encourage fishing was an utter disaster.
The Monoculture Misstep
In theory, pushing for single-crop agriculture (or monoculture) makes farming more efficient. In practice, it allowed pests to breed like crazy and degraded the soil. It also made crops more dependent on chemical pesticides & fertilizers, which is never good. We need diverse crops for farming instead.
The Biofuel Boom-And-Bust
Biofuel involves turning corn into fuel and saving the planet while you’re at it. What could be wrong with that? Well, turning into fuel drove up the price of corn, making this staple food more expensive. Clearing land to grow more corn also increased greenhouse gas emissions. Biofuel was nowhere near as beneficial as we thought it’d be.
The Electric Car Battery Conundrum
Electric cars are all the rage and for good reason—they help us reduce our carbon footprint. However, their batteries require rare earth minerals and mining these minerals is anything but clean & green. We’re still figuring out how to make electric cars truly green from start to finish. The dirty side effects are holding us back!
The Light Bulb Legislation
Many countries have passed legislation to phase out the old, inefficient incandescent light bulbs for more energy-efficient alternatives, like LEDs and CFLs. While they’re great for reducing energy use, the transition wasn’t as smooth as flipping a switch. The higher upfront cost is too much for some households. Even disposing of CFLs is bad for the environment because they contain a small amount of mercury.
Cash for Clunkers
The “Cash for Clunkers” program was designed to get less fuel-efficient cars off the road by giving incentives for people to trade them in for newer, cleaner models. On paper, it sounded great. However, the program also meant thousands of vehicles were scrapped early. Lots of low-income families could’ve used these or they could’ve been sold for parts.
