In December 1872, sailors on a passing ship discovered the Mary Celeste, an American cargo ship, floating in the Atlantic Ocean east of the Azores. There were no people on board the Mary Celeste: its captain and the crew of nine people were all gone. Its lifeboat (a small boat that ships carry for emergency purposes) was missing. Several theories have been proposed to explain what happened to the ten people who had been aboard the Mary Celeste.
One theory is that the crew of the Mary Celeste fell victim to pirates. Pirates in the area were known to attack commercial ships and capture sailors, then the pirates demanded money from the company that had employed the sailors for sailors’ release. The theory is that pirates attacked the Mary Celeste and took everyone on board captive.
A second theory is based on the fact that the Mary Celeste was transporting Flammable liquid stored in barrels. Some of the barrels were found empty when the Mary Celeste was recovered, suggesting they might have leaked during the voyage. The flammable liquid leaking from the barrels may have created a danger of explosion and caused the sailors to escape to the lifeboat to wait until the danger passed. As they were waiting, the lifeboat may have had an accident, and the crew was lost.
The third theory asserts that the captain and crew may have determined that the ship was in danger of sinking. This is supported by the discovery that more than one meter of water had leaked into the ship’s bottom, and only one water pump on the ship was in working order. Rather than wait for the Mary Celeste to sink, the captain may have ordered everyone to get into the lifeboat and use it to reach the safty of the nearby island of Santa Maria.

Many companies provide important products and services but at the same time cause environment damages. Some people believe the way to prevent these companies from damaging the environment is for the government to require more penalties from them, such as higher tax and larger fine. Do you think it is a good idea? Why and why not?
Andrew
A lot of companies make helpful products but hurt the environment too. I think the government should punish them, like raising their taxes and fines, to stop the damage. Doing that would hold corporations accountable and force them to change in an impactful way. We can have both innovation and sustainability if governments incentivize it properly through penalties.
Claire
I disagree that we should penalize corporations more for environmental damage. Many companies are already taking steps to adopt greener practices, and higher taxes or fines could discourage innovation and hurt the economy. Instead of punishing businesses, I believe the government should reward and incentivize sustainable choices through subsidies and tax breaks.
