Bunnies Become Biofuel

Parks in Stockholm (the capital of Sweden) are being overrun with hungry rabbits. To keep the rabbits from destroying the parks, the city of Stockholm hires hunters to reduce the number of rabbits in the parks. The bodies of the rabbits, which can be as many as 6,000 a year, are frozen. And then they're moved to a heating plant, where they turn into fuel to heat Swedish homes.
A survey shows that while some Swedes are okay with using bunny bodies to heat their homes and think it's resourceful, others think this is not a good way to treat rabbits, to put it mildly.

Save the Ocean

The oceans are diminishing. Two-thirds of species in the northern Atlantic are being overfished. Some fish that used to be plentiful have been fished to almost extinction. Also, the gigantic trawling nets that sweep up everything in their path catch unwanted things. A quarter of the fish caught in nets are unwanted. Nets also entangle larger creatures, such as dolphins, drowning them.
Climate change is also affecting the ocean. Warmer waters damage or kill algae that fish feed on. There are then less algae-eating fish around, since some starve to death, which means less food for those animals that would usually eat them. The food chain is knocked off and the whole ecosystem suffers.
