Biodiversity is the number of different species in an area Major environmental issue Why Value of Biodiversity Economic Value They can provide food materials for clothing medicine and other products. The complexity and rich diversity of life found in forests provides many vital services to human beings Nonetheless humans are destroying forest biodiversity at an alarming rate The conversion of forests to agricultural land overgrazing unsustainabl 20 1027200 1048830 1054860 1081860 1126920 1137390 1180200 1192470 1229340 1282710 O7 826440 864840 882600 896730 922290 947580 976770 1005900 1035120 1126920 1204380 O6 612540 672960 717120 717120 719850 750720 754770 754770 797670 873510 918030 O5 What is Biodiversity?. All living things in a food web are connected.. If the numbers of one species are affected it affects the numbers of all other species in the food web..
