CONCLUSION THE USE OF TROPICAL HARDWOOD IS CURTAILED MANIFOLDBECAUSE OF ENVIRONMENTAL REASONS NON- WOOD MATERIALS SUCH AS PLASTICS , METALS,REQUIRE HIGH ENERGY LEADING TO MORE AIR AND WATERPOLLUTION ALMOST ALL PRODUCTS THAT CAN BE MADE FROM WOODCAN ALSO BE MADE FROM BAMBOO GROWTH & USE OF BAMBOO HELP IN FIXING ATMOSPHERICCARBON AND NEEDS LESS ENERGY WHILE PROCESSING BAMBOO PRODUCTS ARE BIODEGRADABLE & DO NOTPOLLUTE THE NATURE.
