for a more sustainable city, we need to ban single use plastics like straws and bags, encourage electric cars and solar panels and cut down meat consumption just to start. this problem is getting too big and out of hand and changes need to become more drastic and are needed sooner. everyone needs to do something before its too late. we need to work together and keep this world liveable for the future generations.

To further elaborate on the transportation aspect, a couple more adjustments can be made. One of the biggest issues in cities is transportation. In cities, congestion is a common occurrence and is a large contributing factor in carbon emissions. A possible solution could be installing smarter stoplights. According to the University of Southampton, the smart traffic lights not only help with congestion, they also have created an economic benefit of 29 million euros from 2009-2014. The economic benefit of the smart traffic lights could be contributed to other ways of creating a more sustainable city. For instance, enhancing the current public transportation system and encouraging other methods of transportation such as bicycling. Examples of this can be seen in Copenhagen, where a bridge was created for the sole use of bikes. Another way to encourage more environmentally friendly transport would be the Bus Rapid Transport (BRT) system in Johannesburg which creates dedicated bus routes. Through promoting eco-friendly transportation and smart traffic lights, the cities can be made much more environmentally sustainable.

I think that the most reliable kind of energy would be solar panels yes they may be expensive and hard to install but its a clean energy and a more eco-friendly energy

I think the same since for years we have been wasting many things due to the fact of not being informed on this topic. And I also think that we all have to start making a change like using less cars and using the bicycle more since it helps us to have good health
