Answer:
25-50%
Step-by-step explanation:
If the statistics are correct and if no changes are made, at the end of the century we will have about 25-50% extinction of the species of living beings that we know today. This will completely change the fauna and flora we know, as well as affect the availability of numerous resources which will impact human life in a drastic way.
For this reason, it is necessary to stimulate projects and attitudes aimed at preserving nature and the life of animals and plants throughout the planet, so that this situation can be reversed.
