The latin america and caribbean (lac) region encompasses countries with great environmental issues. the southern portion of central america to the caribbean's part, including south america presses the major environmental issues like deforestation and   habitat subsistence. the requirement of the whole country and the pressure of export is being done by this region as it possess the soil with highest fertility rate and maximum strength which could us in modifying the various technology for the humankind. because of deforestation, we take animal shelters away from them, so the major issue occurs again which we known as "habitat subsistence". government has to set the target according to the capacity of a certain region which would not affect the environment. then, businesses and organizations have to understand their roles and need to divide the task into several groups (one for each, according to their natural capacity), individuals can the government or statuary body by just following their guidelines and never harm or exploit the environment for our own use.i really hope this you out!
