So why they named it environmental studies rather than history ?

1) 2014 pasun maharashtra education ne primary standards sathi history chi pustak kadhun tyanche nav environmental studies kel ka ?? Hi apli history ahe yat tyanna laj vatat ahe ka lihayla ?? Thaadhi he same pustak itihas karun shikavle jat hote ata kay zal mah as ki history mhanun shikavn band kel 2) ani dusri bab mhanje itihasach pustak pahile 140 pages ch asaych shivaji mahrajanch 4th std sathi je ata fakt 98 pages ch kelay. 3) he sarv changes ani pustak tumhi Ebalbharati var pahu shakta. Tumhala kay vatt he barobar ahe ??
