Science and sports may be beyond politics. BUT may be foriensic science can work together with historians and politcians to trace history of politics. What ever we talk world is one. Transboundary pollution, wildlife migration, and continental biodiversity bordering will make two countries sharing and respect the boder and life. Economy and politic will ultimately quarrel, fighting, jealousy and war. All because of unhealthy life, greedy, bully and domination

Transboundary pollution is pollution that originates in one country but, by crossing the border through pathways of water or air, is able to cause damage to the environment in another country.
