Glaciers are melting, rainforests are dying, sea levels are rising, and wildlife is trying to keep it together. It has become clear that humans have caused most of the past century's warming by releasing heat-trapping gases.

These so-called greenhouse gases have higher levels than in the last 800,000 years. Climate change is a global problem with no borders. To stop or even slow it down we need coordinated work by all countries.

Many say that being a vegan or buying only green will save our environment. That's completely wrong. Being vegan etc. will help our environment but not save us.

To save this world we need to think bigger. A good example is cargo ships. Cargo ships are responsible for more than 18 percent of some air pollutants and therefore one of the biggest causes to the global warming.

Here is a direct quotation from British newspaper iNEWS: "It has been estimated that just one of these container ships, the length of around six football pitches, can produce the same amount of pollution as 50 million cars.

The emissions from 15 of these mega-ships match those from all the cars in the world. And if the shipping industry were a country, it would be ranked between Germany and Japan as the sixth-largest contributor to global CO2 emissions". I made some research about this and how shocking it may sound it really seems true.
