That's a complicated question. In many ways it is less healthy, and in some ways it's more healthy. Between 1950 and now, we've encountered the climate emergency, which is something that didn't exist in 1950, so that's a huge problem that has developed over the last 72 years.
In terms of biodiversity, we've seen massive declines. The latest information from the intergovernmental platform on biodiversity and ecosystem services indicates a 70% decline in wildlife since 1970, so we're clearly much worse off there.
There are some areas where we have taken action since 1950. We've eliminated the use of ozone-depleting chemicals. We've seen a huge rise in renewable forms of energy, so there have been some measures of progress. We have far more protected areas in the world today than we did in 1950.
It's a mixed bag, sir.
