Build back better is a movement that is trying to create a better and fairer world to live in after the coronavirus (COVID-19) pandemic. It's about coming up with ideas for how society, businesses, and governments can work together to make things better for everyone. This means that things like the economy and the environment should be improved, more people should have access to healthcare, and everyone should have the same chances to succeed. To make this happen, governments need to work with businesses, scientists, and everyone in the community to find solutions to help things get better. This can include things like investing in green energy, making healthcare more accessible, or creating more jobs for people who have been affected by the pandemic.
