The time for change is now. It's difficult to understand why people don't want to protect the planet more. It's a really big problem and we are already seeing the effects of climate change. People still drive their cars everywhere and refuse to use public transport. Traffic and pollution in the air are common in big cities. And we throw away plastic bags and aluminium cans, which we should recycle. We need to move to 100 percent renewable energy and stop depending on petrol and oil. We need to protect the oceans and the environment. And we need to do it now or our children may not have a planet to live on.
